Although the income of city consumers rose over 7 percent between the year 1941 and the first quarter of 1942, their average expenditures for current consumption increased less than 2 percent. At the same time living costs went up 7.5 percent. Thus, in the first 3 months after the attack on Pearl Harbor, American city consumers were buying a smaller quantity of goods and services. The conversion of American industry to war production was re flected in increases in money income of 5 percent or more between the two periods, for nearly half the urban consumers in the United States. For this group, income increased enough to offset the increase of 7.5 percent in living costs.2 Over one-fifth had increases that amounted to 25 percent or more. On the other hand, priority un employment, business losses, and other factors caused decreases in income of 5 percent or more for another fifth of the consumers. One-half of the city consumers had annual cash incomes below $1,857 in 1941 as compared with $1,982 in 1942. Single persons, comprising over one-sixth of all consumers, were much more heavily concentrated at the low income levels than were families of two or more. In 1942, 54 percent of the single persons and 15 percent of the families had incomes at an annual rate of less than $1,000. Relatively full employment and the higher wages meant great improvement in incomes as compared with 1935-36. In that year half the urban families of two or more persons had money incomes below $1,295 as compared with $2,215 in 1942. The proportion of families having cash incomes below $1,000 was more than twice as large in the mid-thirties as in 1941 and the winter of 1942. The average increase in income more than balanced the 15-percent rise in living costs from 1935-36 to 1942. The lower the income level in 1941, the larger was the proportion of consumers whose incomes rose 25 percent or more between 1941 and 1942. This was to be expected, because part-time employment or unemployment for some members of the family was a frequent cause* 1The term “consumer” is used to include both families of two or more persons and single consumers. Nearly five-sixths of the consumers were families of two or more. In this article the terms “single persons”' a&id “single consumers” are used synonymously. * Based on a comparison of the Bureau s index of the cost of goods purchased by wage earners and lowersalaried workers in the United States averaged for the year 1941 and for the first quarter of 1942. L 2 INCOME AND SAVING OF CITY FAMILIES of low income in 1941. Full-time employment in 1942 for such persons would result in a large percentage increase in family income. Comparatively few of the high-income families in 1941 had unem ployment, and at their income levels it is not common to have an opportunity to move to a job that within the year pays 25 percent more than the job previously held. Supplementary income in the form of goods and services received as pay, as gift, or as relief was relatively important at the low income levels. The occupancy value of owned homes also represented addi tional income to a large number of families, especially at the high income levels. Supplementary income in 1942 was important enough, when added to money income, to shift over one-fifth of all families and single consumers living in cities into a higher income class. Savings of the average city consumer were 70 percent higher in the first 3 months of 1942 than in the preceding year. In 1942, 11 percent of total money income went into savings as compared with 7 percent in 1941. Consumers whose incomes did not change saved half again as much in 1942 as they saved in an average quarter of 1941. Those with substantially higher incomes saved very much more than in the preceding year. Those who had suffered reductions in income ran into debt in the later period, but they were relatively few in number. The general increase in savings was so large that it represented over two-thirds of the increase in total consumer incomes. Increases in assets and decreases in liabilities made up these increased savings, as well as income taxes paid in advance of due date. War bond and stamp purchases formed a large part of the savings. For low-income consumers, the winter of 1942 brought a large in crease in debt. Increased living costs explain in part their greater difficulty in making ends meet. Thus, fixed-income consumers in the classes below $1,500 spent 7 percent more than in 1941. In addition there was a large number to whom 1942 meant sharply decreased incomes. Food, housing, and medical care accounted for practically the entire rise in expenditures for these groups. In con trast, higher-income city consumers (those with incomes above $1,500) spent less for consumption and saved more in 1942 than those with incomes of that amount in 1941. With new cars and tires rationed, expenditures of the average city consumer for buying and running automobiles were much lower in 1942 than in 1941. Outlays for household furnishings and durable equipment such as stoves and refrigerators were also lower. The only expenditures of the average consumer that showed notable in creases in average amount between 1941 and 1942 were for food, fuel, and medical care. Families usually spend more for medical care and fuel in winter time. Food prices, however, had advanced 11 percent between 1941 and the first quarter of 1942, while expendi tures for food went up only 5 percent. This means that city con sumers were buying less food or the cheaper foods in the first 3 months after the declaration of war. These findings come from the Survey of Family Spending and Saving in Wartime conducted by the Bureau of Labor Statistics among a cross section3 of all city consumers—families and single persons. It was paralleled by a survey of rural consumers by the Bureau of Home 3 For a combined report for the Nation’s families, see Bureau of Labor Statistics Bull. No. 723 and sub* sequent reports. 3 SUMMARY Economics of the United States Department of Agriculture. These form the first Nation-wide study of incomes and expenditures since the Study of Consumer Purchases covering 1935-36. The consumers were interviewed in their homes by trained field agents, using a detailed schedule that covered sources of income, amounts spent for food, clothing, housing, transportation, and all other items entering into current family living, as well as net change in family assets and liabilities. From most consumer units, the information was obtained for both the year 1941 and the first quarter of 1942. Income of All Consumer Units MONEY INCOME Half the families and single persons living in cities had money incomes at the annual rate of $1,982 in the first 3 months of 1942 as compared with $1,857 or less in 1941 (table 1 and chart 1). In both periods, 8 percent of all urban families and single persons had cash incomes below $500. Annual incomes of $3,000 or more, however, were reported by 23 percent of the families in 1942 as com pared with only 19 percent in the preceding year.

He may be married or single. 8A family of 2 or more persons, as defined in this survey, consists of persons who pool their incomes and expenditures. They need not be related nor do they necessarily share the same household although such in stances are infrequent. 4 Less than half of 1 percent. More significant is the fact that decreases of income were more common among the group with incomes of more than $3,000 in 1941 than among those with lower incomes. It is to be noted that at all income levels below $3,000 about 1 out of 5 consumers suffered at least a 5-percent loss of income from 1941 to 1942. Above this level, however, nearly 1 out of 3 faced such a decline and 1 out of 10 a decrease of more than 25 percent. This may not mean that there was more job loss among the higher-income group, but probably does mean that it is harder for persons displaced at the $3,000 income level to find employment producing equivalent income than for those dis placed at the $1,500 level. 4 INCOME AND SAVING OF CITY FAMILIES T able 2.— Comparison of Money lnccmes of City Families and Single Persons, in 12 Months of 1941 and First 3 Months of 1942, by 1941 Money Income Class Percent of families reporting annual rate 1of 1942 income Annual money income class in 1941 All incomes___________________________ Under $1,000__________________________ $1,000 and under $2,000................................... $2,000 and under $3,000..................................... $3,000 and over . ____ _________ _____ Higher than in 1941 Lower than in 1941 Within 5 by— by— percent of Total 1941 25 percent 5 to 25 income 5 to 25 25 percent or more percent percent or more 100 100 100 100 100 22 29 25 18 17 27 24 29 30 21 29 27 27 31 31 14 10 11 15 21 8 10 8 6 10 »For 1942, annual rate was based on first 3 months. As a result of income shifts, some of the $1,000 consumers in 1941 became $1,500 consumers; some of those in the $1,500 income class in 1941 fell in the $1,000 class in 1942 (table 4). It is well, therefore, to consider what the income status in 1941 was for families and single persons now making $1,000 or $2,000 or $3,000, as the case may be {table 3). It will be seen, for example, that nearly 1 in every 3 with an income of less than $1,000 in 1942 had suffered a decline of 5 percent or more in income. On the other hand only about 1 in every $ of those with $3,000 or more in 1942 had had an income reduction of 5 percent or more. Nearly 2 out of 3 of the consumers with $3,000 or more in 1942 had had an increase of income, while only 2 out of 5 of those with incomes of less than $1,000 were better off in 1942 than in 1941. Thus, it is not to be assumed from the discussion of table 2 that the average consumer at low income levels is better off in 1942 than in 1941.4* T able 3. — Comparison of Money Incomes of City Families and Single Persons, in 12 Months of 1941 and First 3 Months of 1942, by 1942 Money Income Class Percent of families reporting annual rate of 1942 income Annual money income class in 1942 All incomes___________________________ Under $1,000 _________ _______________ $1,000 and under $2,000................................... $2,000 and under $3,000.................................... $3,000 and over________________________ Higher than in 1941 Lower than in 1941 by— by— Within 5 percent Total of 1941 25 per 5 to 25 income 25 per 5 to 25 cent cent or percent or percent more more 100 100 100 100 100 22 15 21 21 33 27 23 27 28 30 29 30 29 33 24 14 14 15 14 10 8 18 8 4 3 i For 1942, annual rate was based on first 3 months. * The distinction between tables 2 and 3 is of extreme importance in considering a tax program. There is presumably a larger taxpaying capacity in a family that customarily had an income of $1,200 but now has an income of $1,500 than in a family that has characteristically had about $1,500 and still has. Table 2 shows that about half the families had substantially more income in 1942 than in 1941 and that increases were especially frequent among families that had had less than $2,000 income. Table 3 indicates that the group with less than $1,000 consists of about equal numbers of families with more income than in 1941, with the same income, and with less incon e. In other words, as a group its taxpaying capacity is about the same as in 1941. On the other hand, the taxpaying capacity of the group with incomes of $2,000 to $3,000 in 1942 is larger than in 1941 because it contains 5 families with larger incomes than in 1941 for every 2 whose incomes are smaller. 5 INCOME, ALL CONSUMER UNITS T able 4.— Comparison of Money-Income Distribution of City Families and Single Persons in 12 Months of 1941 and First 3 Months of 1942 Annual money income class in 1941 Under $500.......................................................... $500 and under $1.000......................................... $1,000 and under $1,500....................................... $1,500 and under;$&000....................................... $2,000 and' litider $$060..................................... . $3,000 and over................................ ..................

TOTAL INCOME (INCLUDING INCOME IN KIND) In addition to cash incomes, many families and single persons re ceived supplementary income in the form of home-produced food and food, rent, clothing, or household furnishings as pay, as gift, or from a relief agency. In addition, home owners were credited with income representing the occupancy value of their homes, that is, the difference between the market rental value of the dwelling and the actual expenses incurred for taxes, repairs, insurance, and interest on mortgages. Income in kind was particularly important at the low-income levels, comprising about half again as much as money income, on the average, for families and single persons with money incomes below $500, and over one-sixth as much for those in the next higher income class (table 5). Domestic servants, janitors, institutional and other employees who customarily receive food or lodging as pay, and relief recipients are concentrated in these income groups. At the upper income levels noncash income, consisting principally of the occupancy value of owned homes, averaged larger in amount but was relatively unimportant in relation to cash income.1 T able 5.— Average Money and Other Income of City Families and Single Persons by Money Income Class, 12 Months of 1941 ana First 3 Months of 1942 12 months of 1941 Annual money income class1 Aver age money income All incomes *_____ _ _x_ Under $500............................................................. $500 and under $1,000........................................... $1,000and under $1,500 _ ... ___ _ _ __ $1,500 and under $2,000___________________ $2,000 and Under $2,500................... .................... $2,500 and under $3,000........................................ $3,000 and under $5,000________ ______ _____ $5,000 and under $10,000...................................... $2,188 307 743 1,246 1,750 2,240 2,742 3,732 6,208 Average Average value of value of goods and Aver Aver goods and Aver services age age services age received total * money received total * without income income without income direct direct expense expense $159 144 134 123 137 158 175 202 247 $2,347 $587 75 451 877 182 312 1,369 1,887 436 2,398 556 2,917 685 3,934 932 6,455 1,615 1 For 1942, annual rate of money income was based on first 3 months. 1 Money income plus other income. 1 Includes families with incomes of $10,000 and over.

Income of Families and Single Persons MONEY INCOME Single persons constituted over one-sixth of all consumer units living in cities in 1941 and the winter of 1942. They were much more heavily concentrated in the low-income classes than were families of two or more. However, low-income single persons appear to have benefited more than low-income families by the conversion of industry to a war basis. In both periods, 15 percent of the families of two or more had money incomes below $1,000 per year (table 1), and approximately the same proportion (29 and 27 percent) of single persons had in comes of less than $500 in each period. Incomes of $500 to $1,000, however, were reported by 34 percent of the single persons in 1941 as compared with 27 percent in 1942. Half the city families had money incomes at the rate of $2,215 per year or more in 1942 as compared with $2,083 in 1941. The median income of the single persons increased from $817 in 1941 to $918 in i942. Changes as compared with 1985-S6.—Striking as are the changes in income between 1941 and the first quarter of 1942, the improvement between 1935-36 and the more recent periods is much more impressive. In the period immediately following the depression half of the urban families of two or more are estimated to have had cash incomes below $1,295, as compared with the median annual income of $2,083 in 1941 and $2,215 in 1942. These figures must be compared, however, with a change in living costs of 7.1 percent from 1935-36 to 1941 and 15.2 percent from the former period to the first quarter of 1942.5 Under 5 Based on a comparison of the Bureau’s index of the cost of goods purchased by wage earners and* lowersalaried workers in the United States averaged for the 12 months, July 1935 through June 1936, for the 12 months of 1941, and for the first 3 months of 1942. 7 INCOME, FAMILIES AND SINGLE PERSONS INCOME OF FAMILIES OF TWO OR MORE C ITY FAMILIES AND UNDER $500 TO $ 1,000 m m u srm su r LAB0R $ 1,000 TO $ 1,500 $ 1,500 TO $ 2,000 $ 2,000 TO $ 2,500 $ 2,500 TO $ 3,000 $ 3,000 TO $ 5,000 $ 5,000 AND OVER ,NC0ME ,N D0LLARS conditions of relatively full employment at higher wages, 15 percent of all families of two or more had cash incomes below $1,000 whereas in the mid-thirties 36 percent had less than that amount. . At the other extreme, the 22 percent and the 27 percent having incomes of $3,000 or more in 1941 and 1942, respectively, are in contrast to the 9 per cent with such incomes in 1935-36 (table 7).

The total income distribution was adjusted to a money-income basis by deducting imputed income of home owners. 493470-42-----2 8 INCOME AND SAVING OF CITY FAMILIES TOTAL INCOME Supplementary income in kind appears to be about as important for families as for single persons. Over one-fifth of each group moved into a higher income class in 1942 when classified by total income rather than money income. Low-income single persons are likely to work as domestic servants and institutional employees and frequently receive food and rent as pay. Families of two or more are more likely than single persons to receive relief. Also, they much more fre quently own their homes. , Spending and Saving All Incomes 6 Savings by city consumers were about 70 percent higher in the first 3 months of 1942 than in 1941 (table 8), and formed over 11 percent of money income in the 3-month period as compared with 7 percent in the preceding year. Consumers whose incomes did not change saved half again as much as they saved in an average quarter of 1941. Those whose incomes had increased substantially saved an exception ally large amount in 1942—57 percent of their increase in income. Families and single persons whose incomes were substantially lower in 1942 had large deficits in that period, but they were small in number as compared with those with higher incomes. The general increase in savings was so large that it represented two-thirds of the increase in total city consumer incomes. War bond and stamp purchases formed a large part of these new savings. The savings figures are based on the consumers’ own statements about net change in each class of their assets and liabilities during the year and the quarter, respectively. Included as savings are reductions in past debts of all kinds, as well as additions to present holdings in the form of cash, real estate, stocks or bonds, or other securities. Payments of life-insurance premiums are treated as a part of savings, as are payments on principal of mortgage or improve ments on homes or other real estate owned by the family, and con tributions for old-age and unemployment insurance paid by the individual. Savings also include advance payments on Federal in come tax (that is amounts actually paid in excess of the one-fourth of the year’s tax on 1941 income which was due during the first quar ter). To the extent that families were cutting down on their con sumption during the first quarter in order to meet their advance tax payments, the level of savings for the remainder of the year may be expected to be somewhat lower. Deficits include increases in balances owing on installment and other credit accounts, in amounts owed to banks, loan companies, etc., amounts due in taxes, and net amounts received from sale of holdings. Personal-tax payments, averaging $22 for the entire year, took only 1 percent of the cash income of the average city consumer in 1941. In the first 3 months of 1942 such taxes amounted to $16 ($64 per year), or 2.7 percent of income. Federal and State income taxes, 6 Averages for all families do not represent the saving or consumption of “typical” Americans, or of any identifiable group, since they are merely an arithmetic average of the spending of the rich and the poor as well as those in the middle-income classes and of single consumers as well as families. Although the average spending of each income class is weighted by the proportion of all consumers in that class, in arriving at the general average, the large amounts spent and saved by high-income consumers give each of these few con sumers a much heavier influence upon the average amounts than each of the many consumers at the lower end of the income scale. However, such general averages provide a useful cross-section picture for this par ticular period to which they refer. 9 SPENDING AND SAVING, ALL INCOMES poll taxes, and personal-property taxes, due in January, February, or March, make up these average figures. Taxes on real estate and on automobiles and excise and sales taxes are not included in these figures but are combined with the items to which they apply.

Gifts to persons and contributions to relatives and to welfare, religious, and war-relief organizations were over four times as impor tant as tax payments in the case of the average city consumer in 1941. In the winter of 1942, however, such gifts and contributions amounted to only slightly more than tax payments and, when estimated on an annual rate, were somewhat smaller than in 1941. This undoubtedly reflects the fact that personal gifts are largely concentrated at the Christmas season and that community-chest drives in most cities are held in the fall. The only expenditures of the average consumer that showed notable increases in average amount between 1941 and 1942 were for food, fuel, and medical care. Families usually spend more for medical care and fuel in winter time. Food prices, however, had advanced 11 percent between 1941 and the first quarter of 1942, whereas expenditures for food went up only 5 percent. This means that families and single persons were buying less food or cheaper food in 1942 than in 1941. With new cars and tires rationed, expenditures for buying and running automobiles were much lower in 1942 than in 1941. Outlays for household furnishings and durable equipment, such as stoves and refrigerators, were also lower. 10 SPENDING AND SAVING OF CITY FAMILIES , Spending and Saving by Income Level When savings of consumers at different income levels (table 9) are compared, deficits at the lower income levels give way to progressively larger savings at the higher income levels. This was true both in 1941 and the first part of 1942, although in the later period both extremes were accentuated; deficits at low levels were greater and savings at high levels were greater. The savings, figures at every income level are in themselves averages made up of some families and single persons with net savings and others with net deficits. Thus, even at the under-$500 income level, some consumers managed substantial savings, whereas others with incomes as high as $10,000 ended the year or the quarter in the red. At the lower levels, however, the proportion of consumers incurring deficits and the amounts of their deficits were so great as to more than outweigh the smaller proportion with net savings. 11 SPENDING AND SAVING, BY INCOME LEVEL T able 9. — Average Money Income and Outlay,1 City Families and Single Persons, by Money Income Class 12 MONTHS OF 1941 Annual money income class M oney income , 1941 Under $500....................................................................... $500 and under $1.000...................................................... $1,000 and under $1,500................................................... $1,600 and under $2,000................................................... $2,000 and under $2,500................................................... $2,500 and under $3,000................................................... $3,000 and under $5,000................................................... $5,000 and under $10,000.................................................

SPENDING AND SAVING OF CITY FAMILIES to SPENDING AND SAVING, BY INCOME LEVEL 13 For low-income consumers, on the average, the first quarter of 1942 brought a large increase in debt. While savings for the entire group of city consumers were increasing by 70 percent, and the savings, in in come levels from $1,500 to $10,000 by 75 percent, consumers at the lowest levels were incurring debts or withdrawing from past savings to the extent of $21 during the quarter. This compares with a quarterly average decrease in assets or increase in liabilities during 1941 of $10. The inability of the low-income groups to make ends meet during the first 3 months of 1942 is partly explained by increased living costs. Thus, families and single persons with incomes below $1,500 in 1942 and almost the same income in 1941 spent 7 percent more in the later than in the earlier period. This increase in expenditures almost exactly matched the 7.5-percent increase in living costs that occurred between the two periods. Those with fixed incomes, however, met such increases in living costs by incurring debts or drawing on past savings. In addition to the substantial number with fixed incomes there was a large number of consumers to whom 1942 meant sharply decreased incomes. Thus, fully one-sixth of all those with incomes below $1,500 in 1942 had incomes in 1941 which were more than 33 percent higher. These consumers, in many cases the victims of priority unemploy ment, were unable to lower their level of living to the full extent of their decline in income. They incurred debts or made withdrawals from past savings. The increase in expenditures at these lowest levels was not scattered among all items of expenditure, however. Food, housing, and medical care each came in for higher expenditures during 1942. Thus, while at the income level $500 to $1,000 total expenditures increased by $78 per year, expenditures for food, housing, and medical care increased bv $76. About 44 percent of the money income of all city consumers with incomes between $500 and $1,000 went for food, and another 28 per cent for housing, fuel, and light, in the early months of 1 9 4 2 , as com pared with 40 and 24 percent, respectively, for those with similar incomes in 1941. With clothing and other essentials to be bought, the debts of families in this group amounted to 17 percent of the total of their current cash incomes. In contrast with the consumers at the lower income levels, families with incomes above $1,500 in 1942 spent less for current consumption and saved more than families with incomes of that amount had done in 1941. The combined effect of the wartime cessation of the produc tion of durable goods and the increased volume of war-bond purchases was apparent in the sharply increased savings at each income level of consumers whose incomes were the same in 1941 and 1942. One-fourth of the families and single persons with 1942 incomes above $1,500, however, were those who had received income increases of 25 percent or more. Their level of living did not increase to nearly the same extent as their income. Their income increases were in large part devoted to paying off old debts and buying war bonds. The decre|ses in expenditure at income levels above $1,500 were concentrated in two groups—automobiles and furnishings. Since expenditures for other items in the aggregate showed only a small decline, it may be concluded that the sharp increases in savings at these levels were made possible chiefly by the reduction in the expendi tures for these two groups. 14 SPENDING AND SAVING OF CITY FAMILIES T able 10.— Average Money Expenditures of City Families and 12 MONTHS Annual money income clast Total Food M oney income , 1941 Under $500................................................ $500 and under $1,000.............................. $1,000 and under $1,500........................... $1,500 and under $2,000.........................._ $2,000 and under $2,500........................... $2,500 and under $3,000........................... $3,000 and under $5,000.......................... $5,000 and under $10,000......................... $420 $167 295 750 433 1,215 1,671 558 674 2,103 784 2,516 3,246 973 4,704 1,311 Housing, House Furnish fuel, ings Cloth Auto hold light, and ing mobile refriger opera equip tion ation ment $103 177 271 344 405 456 534 682 $20 33 50 71 92 112 152 275 $8 22 50 89 123 153 193 228 $29 71 128 184 242 303 421 673 $16 33 81 148 210 265 353 496 9.5 9.5 10.2 10.5 10.8 11.0 11.3 10.9 5.1 4.4 6.5 8.4 9.4 9.7 9.4 8.0 Percent of money income1 Under $500............................................... 136.5 $500 and under $1,000.............................

Personal-tax payments at the lowest income levels represent mostly poll taxes and occasional small amounts of personal-property taxes. In .some instances, however, consumers whose incomes in the 1942 period were greatly reduced from the previous year were paying income tax on the previous year’s income. At the higher incomes where income-tax returns are the most important part of the total personaltax figure, the tax rose both in dollars and as a percentage of income. The rise was much steeper in 1942 than in 1941, largely as a result of higher tax rates and lowered exemptions.

These figures cannot be used, however, as a measure of the distribu tion of the total tax burden of the Nation among consumers at various income levels. Such a measure would have to take account of such other taxes as excise, sales, gasoline, and automobile taxes, as well as taxes on homes and other miscellaneous taxes.7 This calculation would show much higher tax pa3^ments at lower income levels than are indicated in the present figures. 7The latest such study is TNEC Monograph No. 3: Who Pays the Taxes, by Gerhard Colm and Helen Tarasov.

They have stimulated many questions as to the methods by which the sample was drawn and its reliability. This appendix attempts to answer these questions. The method of drawing the sample differs in several important respects from those followed in earlier surveys of family incomes and expenditures. These changes were deliberately made, in accordance with the latest developments in sampling theory, to insure greatest possible efficiency and reliability in yielding national estimates. The coverage of total population, that is, the inclusion in the sample of all segments of the population (such as relief, foreign-born, broken fam ilies, single consumers, certain occupational groups or city-size classes) is more complete than in any previous survey. Altogether 1,300 families and single consumers (referred to here as consumer units) in 62 cities were covered. They represent all regions of the country and cities in every size class from those with a popula tion of 2,500 persons to the largest city in the country. In selecting these cities, proper emphasis was given to each of the following factors: Region, city-size class, proximity to a metropolis, racial composition of population, median monthly rent and rental value. The number of interviews obtained in each of the 62 cities was pro portioned to the total population in that city and in all other cities of similar characteristics not actually covered. The interviews within each selected city were assigned in such a way as to give every family and single consumer in each selected city an equal chance to be included in the sample. Furthermore, in cities with populations over 50,000, for which 1940 census data on average rent by block could be obtained, the selection among blocks was carried out in such a way as to include the correct proportion of blocks at each rent level. The final result constitutes an estimate for the entire urban population of the country. The size of sample is smaller than in any previous survey on which national estimates have been based. The smallness of the sample yields positive advantages ip speed of completion, cost, quality of personnel, avoidance of bias, and simplicity of tabulation. Reliability for the purpose of national estimates of a sample of this size, when selected subject to the careful controls described, is confirmed by theoretical tests and also by comparison of the results yielded by the actual sample drawn with census data and other data from inde pendent sources. The internal consistency of the sample data them selves is another indication of the adequacy of the sample size for the pin-pose of national estimates. The general patterns of spending are entirely consistent with the results obtained in 1935-36 from a much more extensive but less inclusive sample. The points at which 17 18 SPENDING AND SAVING OF CITY FAMILIES divergencies are noted, as in expenditures for automobiles, other durable goods, and clothing, and in savings, are the very points at which known changes in general conditions account for current behavior. The comparisons of spending of city, rural nonfarm, and farm consumers at comparable income levels are remarkably consistent. The sample is too small, however, to yield reliable estimates for localities. It is also too small to yield an analysis of the separate effects upon spending of other factors in addition to income, such as region, city size, occupational group, family composition, nativity, etc. A considerably larger sample would be required for these purposes. Since, however, by the very process of sampling followed, all of these characteristics have been allowed to fall as they come in the total population, the composite averages at an income level yield an excellent estimate for the total population at that income level. Further tests of reliability and comparisons with independent data from other sources will be made when detailed tabulations have been completed and when the data from city consumers collected by the Bureau of Labor Statistics have been combined with those for farm and rural nonfarm consumers collected by the Bureau of Home Eco nomics of the United States Department of Agriculture. General Considerations SIZE OF SAMPLE The estimates for city consumers from the Survey of Family Spend ing and Saving in Wartime are based upon information provided by nearly 1,300 families and single consumers surveyed by the Bureau of Labor Statistics. A total of 1,700 rural consumer units were surveyed by the Bureau of Home Economics of whom about 800 lived on farms. Thus the total for nonfarm consumer units is about 2,200, and for farm and nonfarm consumer units combined about 3,000. The Consumer Purchases Study of 1935-36 (conducted by the Bureau of Labor Statistics and the Bureau of Home Economics in cooperation with the National Resources Committee and the Works Progress Administration), which provided the bulk of the data used by the National Resources Committee8 in its estimates of national income and expenditure for that period, obtained income information from about 300,000 families, and information on expenditures from about 60,000 families. The Study of Money Disbursements of Wage Earners and Lower-Salaried Workers, 1934-36, which provided re vised weights for the Bureau of Labor Statistics cost-of-living index, covered over 14,000 families. The Bureau of Labor Statistics survey made during the period 1917-19 included over 12,000 families, while the two pre-World War I surveys made by the Bureau each included in excess of 5,000 families. The present survey is consequently the smallest official survey undertaken in this country for estimating income and expenditure even for one occupational group on a national basis. 8 National Resources Planning Board (National Resources Committee), Consumer Incomes in the United States, Washington, Government Printing Office, 1938; Consumer Expenditures in the United States, Washington, Government Printing Office, 1939; Family Expenditures in the United States, Sta* tistical Tables and Appendixes, Washington, Government Printing Office, 1941. APPENDIX 19 PURPOSE Despite its relatively small size, the present sample yields general estimates of income and expenditure by the Nation's consumers of at least the same accuracy as those which could have been derived from any of the preceding surveys. It was designed with the sole purpose of providing such estimates, whereas all previous surveys of family income and expenditure have been designed with quite different pur poses in mind. The Consumer Purchases Study, for example, was. originally conceived as an inquiry into the differing effects of income, family type, occupation, region, and degree of urbanization upon expenditure. The Study of Money Disbursements of Wage Earners and Clerical Workers and the 1917-19 survey of wage earners were both designed to obtain weights for cost-of-living indexes in specific cities. The 1891 study of the Commissioner of Labor was undertaken to provide data useful in revisions of prevailing tariffs. LIMITATIONS OF EARLIER STUDIES The original purpose of the Consumer Purchases Study led to a sample design suitable for that purpose, but with several important drawbacks from the viewpoint of national estimates. Thus, expendi ture data were not obtained in that study from any family which had been on relief at any time during the year, which did not contain both a husband and a wife, or in which either spouse was foreign-born. In New York City, the most extreme case, but one which includes 10 percent of the urban population, these restrictions, plus several others peculiar to the sampling in that city, meant that only one-seventh of the population of that city was eligible for inclusion in the sample. Similarly, the choice of communities surveyed in the Consumer Purchases Study, while entirely adequate for the purposes of revealing the effect of degree of urbanization upon income and expenditure, was not the most satisfactory for preparing national estimates. Thus, suburban areas surrounding large metropolises, containing almost 17 million persons in 1930, were virtually unrepresented. Only 7 cities, with populations over 100,000 were included, although such cities include about half the urban population. No urban areas in the West South Central States, containing almost 4.5 million city residents in 1930, were covered. The rural nonfarm sample included villages but no open country. The limitations of earlier Bureau of Labor Statistics studies to certain occupational groups in cities selected because of their industrial or commercial importance meant that their results could not be projected to the entire population with any certainty. COVERAGE OF TOTAL POPULATION The sample for the present study, designed for the purpose of ob taining national estimates, avoids these difficulties. The communities covered comprise a complete cross section of the Nation's cities and towns. The sample obtains for the first time information on the relative number of single consumers (i. e. persons not sharing their* incomes and their living quarters with any other persons), their dis tribution by income level, and their expenditures at each income level. In addition, it is the only survey which has ever obtained compre 20 SPENDING AND SAVING OF CITY FAMILIES hensive information on the incomes and expenditures of all of the following classes of the population in addition to so-called “normal” nonrelief families: relief families, families with foreign-born heads, and those lacking one spouse. PERSONNEL Before preceding to a detailed consideration of the present sample it is helpful to recall one positive advantage of small as compared with large samples,' which although well known, is frequently overlooked— the caliber of the agents who obtain the information from families. Particularly, in a study with as extensive a schedule form as that neces sary in surveys of income and expenditure, the quality of the inter viewers is an important consideration. In a survey of the scope of the Consumer Purchases Study, it is necessary to hire as many as 50 agents in towns with no more than 25,000 inhabitants. It is not always possible to find 50 persons in a small town who are at the same time diplomatic and capable of mastering the double entry bookkeeping in volved in determining a family's income, expenditure, and saving. In the present survey only one worker was employed in most of the towns covered. In even very small towns it was therefore possible to find qualified personnel. AVOIDANCE OF BIAS IN THE CURRENT SURVEY In drawing a sample as small as the present one, it was possible to use great care in the actual selection of the consumer units to be sur veyed. All controls were centralized in the Washington office, thus avoiding biases resulting from differing interpretations of instructions by local supervisors or enumerators The block listings, described in a later section, were all sent to Washington for the actual drawing of addresses or designations of consumer units. All substitute addresses were drawn in Washington, none were left to the discretion of agents. The percentage of refusals was very low. Less than 7 percent of the families originally selected failed to supply the information requested. This compares with a substitution rate of approximately 15 percent in the urban series of the Consumer Purchases Study. A contributing factor to this lower rate was the willingness of families to cooperate in view of the war situation, as compared with public attitudes immedi ately following the depression. Another factor was the relatively high ability of the agents in this survey. An additional advantage made possible by a small sample is the more intensive editing which can be given each family report. Thus in the present survey only four schedules were discarded for inconsistency or patent error. It was thus possible to avoid biases which may result from large-scale surveys in which a greater proportion of schedules from families with complicated finances are discarded because they do not come within the tolerable limits of discrepancy. Experiment To Test Adequacy of a Small Sample Before this survey was undertaken an experiment was made to test the extent to which a small sample could estimate one charac teristic of the entire urban population. The test was so designed as to draw 5 independent samples, each consisting of 50 cities and 1,000 families. From each of these samples an estimate of the distribution 21 APPENDIX of urban home owners by value of home and of urban renters by monthly rent was prepared. Comparison of each of these five samples with the actual distribution of 20 million urban renters and owners as shown by the 1930 census gives an indication of the essential accuracy of a small sample.

In the first sample, 50 cities were chosen in the same fashion as the 62 cities actually used in the present sample (see pp. 29 ff.), except fewer controls were used; region and city size were the only bases of stratification. (Each additional pertinent control increases sample accuracyi) The same methods were used in allocating the ! ,000 cases among the 50 cities as were used in the present sample. To select the “sample cases” within each of the 50 cities each of the “sample families” was located in a census rent class or rental-value class by selection of a random number. The samples in each of the 50 cities were pooled to yield an estimate for all cities in the United States. The same experiment was repeated 4 additional times, each time drawing a different combination of 50 cities and each time selecting 1,000 “sample cases” within rent classes or rental-value classes by use of random numbers. For additional comparison a sixth sample was prepared composed of the 42 cities from the Study of Consumer Purchases used by the National Resources Committee in its estimates of income and ex penditure. The rent and rental value distributions as shown by the 1930 census for each of these 42 cities were weighted together using the population weights developed by the National Resources Com mittee. This yielded a sixth estimate of the distribution by rent or rental-value class of urban home owners and renters. This estimate 22 SPENDING AND SAVING OF CITY FAMILIES is, in effect, based upon a sample of several million families (since it uses census figures from a complete enumeration within each of the 42 cities) and is directly comparable with those based upon 1,000 families. All six estimates are shown in table 11, together with the actual distribution by rent class of urban families as shown by the 1930 census. Two general conclusions emerge from this experiment: (1) That a sample as small as 1,000 cases can, if properly selected, give estimates of a high order of accuracy; (2) that estimates based upon large samples, but not covering all sections of the urban population will give less accurate estimates than small samples which do not exclude any section of the population. Specifically, a complete enumeration of the population living in the 42 cities used by the National Resources Committee will give less accurate estimates than a sample of 1,000 living in 50 cities when the cities are selected so as to cover all sections of the urban population. While it is generally recognized that size of sample alone is no guar antee of accuracy, these conclusions may seem little short of paradoxi cal. The explanation lies in the manner in which the cities included in the sixth sample were selected. Only 7 cities with populations above 100,000 were included, although such cities contain about half the urban population. Each of the 5 samples drawn in the experiment included 25 such cities. The sixth sample of 42 cities, did not have complete regional coverage; it had no cities with popu lations below 9,000; it included no small cities lying within metropoli tan areas. Despite the several million families that sample included, it consequently gives poorer estimates of median rent than any of the 5 experimental samples of 1,000 and poorer estimates of median rental value than 4 of the 5. Comparisons of Estimates Based on Actual Survey Sample With Results From Other Agencies The experiment described in the preceding paragraphs is an indica tion of the reliability of a sample of 1,000 cases when drawn from a population which is completely listed. The same results could have been predicted by the theory of probability. Because it is rarely possible in a Nation-wide study of this character to make certain that every family will have an equal chance of being included, an actual field sample of this size may have larger errors. To check on this point the following tables offer a comparison of certain characteristics of the families in the sample actually drawn in cities in the Survey of Family Spending and Saving in Wartime with comparable character istics as measured by the census. AGE DISTRIBUTION OF POPULATION The age distribution of the individuals in the survey sample is com pared in table 12 with that of all urban persons in April 1940 as shown by the Bureau of the Census. In general the distributions check well* There are several sources of disagreement, however, which should be remembered in any detailed comparison of the distributions. 1. The sample applies to a period 2 years after that of the census. This means first that the sample age distributions will apply to a some 23 APPENDIX what older population than those of the census and, secondly, will exclude males in the armed forces at the time of scheduling but in civil life at the time of the census. 2. It is known that every census has underenumerated children less than 5 years old. Such an underenumeration is considerably less likely in the present survey since special expenses of such children, as for clothing, are called for on the schedule form. 3. There appears to be some tendency for women in their late twenties and in their thirties to underreport their age to the census enumerator. Thus, in almost every census the number of native-born women 20 to 24 has been above the expected survivorship from age 10 to 14 as returned 10 years previous.9 T able 12.— Age Distribution, A ll Urban Areas, by Sex— Bureau of Labor Statistics Sample and Bureau of the Census Age 14 or less........ 15-24.............. 25-34.............. 35-44.............. 45-54.............. 55-64............. 65 and over..

An independent estimate of the distribution of the urban popula tion by age and sex in April 1942, with the military and institutional population subtracted, in general shows even closer agreement with the sample distribution. CHARACTERISTICS OF HOUSING Table 13 compares certain characteristics of housing in cities over 50,000 as estimated by the sample and as shown by the 1940 census. Because of the 2-year difference in the period to which they refer and the fact that an occupied dwelling unit, as defined by the census, is not the same as an economic family, as defined in this study, perfect agreement was not to be expected. Nevertheless, the general agree ment is close.

Most of them must wait on a combination of the data for urban families with similar data for rural families collected by the Bureau of Home Economics and adjustment of the resulting figures for comparability of definitions with the estimates of other agencies. Preliminary work in this direction indicates close checks for the follow ing items: Aggregate national food expenditure; aggregate" national purchases of war bonds; percentage change in aggregate savings by individuals, 1941 to first quarter of 1942; aggregate national furniture expenditure; total registration of passenger automobiles. Consistency of Sample Data An additional way in which the usefulness of a sample of the present size may be appraised is by the consistency of the results obtained, particularly when the sample is broken into small subgroups.10 The most well-known of these consistencies, confirmed by over a century of surveys of family incomes and expenditures, is the differing relation between income and expenditure for different groups of commodities and services. Chart 5, which shows average expenditure in 1941 at different income levels, for food, clothing, and savings, presents an example of this consistency.*11 The smoothness of the change from income level to income level is all that could be asked from a sample of any size. The behavior of these curves when based upon too small a sample for the purpose at hand is exceedingly irregular, as may be confirmed by inspection of some of the samples for individual cities in the Consumer Purchases Study, the Study of Money Dis bursements of Wage Earners and Clerical Workers, or the 1917-19 Cost-of-Living Study. CONSISTENCY AMONG SMALL SUBGROUPS WITH CHANGED INCOMES A more striking illustration of the consistency of the data when broken into small subgroups is afforded by classifying families not only by income but also by whether they had recently experienced an increase or a decrease in income. In absence of data, it has frequently been assumed that when a family moves from one income bracket to another it adopts the consumption habits of the families in the new income bracket. The classification of families by both present income and whether income has increased or decreased indi cates that this assumption is subject to some error, at least over rela tively short-time periods. Food expenditures in 1942 are shown separately in table 14 for families having income decreases and those having income increases of 5 percent or more between 1941 and the This device of testing the stability of a sample by testing the consistency of subgroups is one which has found special application in the field of industrial testing and quality control. Walter A. Shewhart: Statis tical method from the viewpoint of quality control. Washington, 1939, pp. 33-36. 11 Although the estimates of expenditure at different income levels published in the main part of this bulletin have been smoothed to eliminate slight irregularities, the data published in this section are all un smoothed, i. e., the averages yielded directly by the original reports are shown. When small samples are subdivided, the results should show some irregularities. The results are smoothed in the body of the report to eliminate these irregularities because it increases the accuracy of the result. For example, it is obvious that medical expenditures depend on sickness in the family. It is largely a matter of chance whether severe illness strikes a family with $1,500 or $2,000 of income. In a small sample the average expenditure for medical care will therefore be higher for families of $1,500 than for families of $2,000, if, among the families selected, those with $1,500 happen to have had extraordinary illness while those with $2,000 did not. But if through out the rest of the sample one finds that medical expenditures rise with income, it is more accurate to con sider this general tendency and to estimate medical expenditures at various income levels from all the cases than it is to assume that the irregularity indicated by the small sample would hold also for a large sample. APPENDIX 25 first quarter of 1942. The table indicates that present consumption is influenced not only by present but by past income. Although the difference in food expenditures between the 2 subgroups does not average more than $25 at any income level below $5,000, the present sample is sufficiently large to detect it at every income level. SUBGROUPS SHOWING INCOME DISTRIBUTION BY AVERAGE RENT OF BLOCK A third example of consistency within subgroups of the sample is the income distribution of families and single persons by the average rent of the block in which they live. As explained on page 32, average block rent in April 1940 as reported by the Bureau of the Census was one of the bases used in selecting the sample of families in cities above 50,000. Chart 6 shows income distributions separately for families living in the lowest sixth of the rent blocks and the highest sixth. The chart is useful not merely in showing that average block rent is related to the income distribution of the families living there. It demonstrates that a sample of the present size can be broken into small subgroups and still show consistent differences. Examples of this type can be multiplied indefinitely. Anyone who works con tinuously with the sample data cannot but be impressed with innumer able cases of this type. 26 SPENDING AND SAVING OF CITY FAMILIES DISTRIBUTION BY 1941 INCOME OF CONSUMER UNITS LIVING IN BLOCKS WITH HIGHEST AND LOWEST AVERAGE RENTS p er c e n t CITIES 50,000 AND OVER 1000 2000 3000 2000 3000 5000 INCOME CLASS IN DOLLARS AND UNDER AND UNDER AND UNDER T able 14,— Quarterly Food Expenditure, Consumer Units With Income Changes, City Families and Single Consumers, First Quarter of 1942 Money income,1first quarter of 1942 Under $500.................................. $500 and under $1,000................ $1,000 and under $1,500............. $1,500 and under $2,000............. $2,000 and under $2,500............. $2,500 and under $3,000............. $3,000 and under $5,000............ $5,000 and under $10,000...........

Selection of Survey Sample The sample of urban families has been selected from 62 cities12 scattered throughout the country. For any stated number of fami lies, the larger the number of communities covered, the smaller is the sampling error. Thus, the only limit to the number of cities included 12 Cities are urban places with population of 2,500 or more as designated by the Bureau of the Census. 27 APPENDIX in any sample is supplied by considerations of cost, since it is generally less expensive to cover a fixed number of families in a smaller than in a larger number of cities. The cost factors associated with the present survey indicated that the most efficient disposition of available funds (solely from the point of view of minimum sampling error) would have involved taking approximately 90 cities. That number of cities, how ever, would have implied an average of less than 15 families per city. Since the compensation for interviewing this number of families would have been too low to attract any large number of capable interviewers, the number of cities was reduced to 62 to provide an average of approxi mately 20 families per city. SELECTION OF CITIES The communities were so selected as to give proper representation to (1) each city-size group, (2) proximity to a metropolis (for cities* under 50,000), (3) each region and State, (4) low-, medium-, and high-rent cities, (5) cities of differing racial composition. A comparison of the distribution of sample cities with that of the total urban population among 6 city-size classes is shown in table 15. The distribution of the sample cities among the 6 city-size classes was made in accordance with the standard sampling formulae, that is,, approximately in proportion to population, and had the effect of in cluding all 14 cities with populations in excess of 500,000 and a de creasing proportion of the smaller cities.

For the selection of the 14 sample cities in the size class of 100,000 to 500,000, and the 14 cities in the size class of 50,000 to 100,000, a three-way set of controls based on the following factors was imposed: Region; 1930 median rent and rental value13 percentage of families in 1930 which were Negro. Each of these controls had the effect of specifying the distribution of 14 cities by the differing value of the control. A comparison of the distribution of the total population living in cities 100,000 to 500,000 by region and of the selected sample cities by region is shown in table 16. The distribution of the sample communities by these regions was obtained in the same fashion as the distribution of all 62 cities among 13 At the time the sample was drawn, 1940 rent was not available for most of the cities in the country. Subsequent experiments have shown that the differences between stratifications based upon 1940 and 1930 rents are slight. 28 SPENDING AND SAVING OF CITY FAMILIES city-size classes, that is, approximately in proportion to total urban population in each. Similar distributions of cities and of total popula tions within this city-size class were obtained by 1930 median rent class and by percentage of population which was reported Negro in the 1930 census. Fourteen cities were then selected completely at random within the limits that they satisfy each of these three criteria. After having imposed these controls, random selection of communities seemed less likely to bias the sample than a system of selecting “typical” or “representative” cities. For cities of 50,000 to 100,000 the procedure was identical with that just described for selection of cities from 100,000 to 500,000. For the remaining 3 city-size classes the procedure differed only to the extent of an additional control for the presence or absence of the city within a metropolitan area. As a final control on all the cities with populations below 500,000 a State control was imposed so that each State (or, for the smaller States, each group of States) received the exact number of cities which its urban population justified.

APPORTIONMENT OF INTERVIEWS AMONG SELECTED CITIES In determining the number of consumer units to be interviewed in •each city the total number of interviews was distributed among the various region city-size groups on the basis of number of occupied dwelling units in each group in April 1940 as reported by the census. For the cities with population of 500,000 and over the number of interviews in each region so obtained was distributed among all the cities in that region on the basis of the number of occupied dwelling units in each city. For cities under 500,000, the number of inter views in each region city-size group was distributed on the basis of the number of occupied dwelling units in the median-rent group of cities from which the selected city had been drawn. Interviews allocated on this basis yielded a sample which would yield estimates of urban income, expenditure, and saving simply by pooling the schedules collected from all cities without weighting. (The absence of weighting is a great saving in time and hence in cost of preparing over-all figures.)

For each city with a population above 50,000 the Bmeau of the Census has computed the average rent or rental value for each block in the city. For such cities, average block rent in 1940 was used as the basis of stratifica tion for selection of blocks. In each such city the blocks were sorted into a series of rent classes, each rent class having the same number of occupied dwelling units.14 One block was selected at random from each of these rent classes. As many blocks were selected as there were families to be interviewed. The procedure was such that the greater the number of occupied dwelling units in a block, the greater was the chance of selecting that block. As a result it was possible to select one family per block regardless of the size of the block, and still obtain an unbiased distribution of families by the density of the block in which they live. A comparison of the average monthly rent per block for the sample and for the entire city in each15 of the cities over 50,000 is shown in table 18.

For cities with populations below 50,000 average block rent has not been computed by the Bureau of the Census, and a somewhat dif ferent procedure was therefore necessary. For each such city in the sample a detailed block map was obtained and the blocks on the map 14 In cities with populations above 500,000 only one-third of the blocks, selected at random, were used in this classification. 15 At the time that the sample of blocks was being drawn, the census tabulations of average block rent in New York City had not yet been prepared. The procedure followed in that city involved treating each of the 3,000 census tracts in that city in the same fashion as blocks had been treated in other cities. The num ber of occupied dwelling units in each tract in April 1940 was known. Since average tract rent was unknown, however, the basis of stratification was percentage of rented units renting for less than $30 in 1934 as shown by the Real Property Inventory. After the sample tracts had all been drawn in the same manner as blocks were drawn in other cities, one block was selected completely at random from each sampled tract. APPENDIX 31 numbered consecutively. Every nth block was then selected, the initial number being chosen at random. Since adjacent blocks were given consecutive numbers, this procedure had the effect of scatter ing the selected blocks throughout the city. The last step in selecting the specific families to be interviewed in the selected cities, involved having the enumerator prepare a complete listing of the families and single consumers living in each of the selected blocks. Each known family or single consumer was listed as a sepa rate unit. These listings were returned to the Washington office of the survey, where the selection of the consumer units to be inter viewed was made. In the cities over 50,000 one consumer unit was selected at random from each block listing; in each of the cities under 50,000 the listings for each of the blocks were put together to form one continuous listing. Every nth family was selected from this con tinuous listing, with the initial number again chosen at random. In the smaller towns some of the blocks thus furnished two or even three families while others furnished none in proper accordance with the density of population within the blocks. Exactly 1,200 consumer units were assigned from such listing. On occasion it was discovered that an assigned consumer unit actually consisted of two or more independent economic units. This happened most typically when two groups of related persons living together and listed as one family in the initial block listing were discovered on more detailed investigation to keep their incomes and expenditures separate. In such a case, despite the relationship, they are best considered sepa rate economic units. In every such instance each of the independent units was separately scheduled. Any procedure which involved taking only one of the economic families in such a multiple grouping would have yielded a sample with fewer economic families living in multiple groups than existed in the urban population. The procedure followed in the present survey involved scheduling each of the sepa rate economic families composing the assigned family. The 1,200 original assignments thus yielded almost 1,300 economic families of one or more than one persons. In the most extreme case a single assignment yielded four separate economic units.16 » The converse of this case should also be noted. In some few cases two or more members of a single eco nomic family were listed separately and one of the members selected for scheduling. To have scheduled the entire economic family of which the selected individual was a member would have overweighted the sample with such families. The procedure followed involved scheduling the entire family if the selected member was the first in the listing of the members, and drawing another family from the block if he was not.
