During Children’s Year, the second year of the participation of the United States in the World War, the Children’s Bureau, conducted a series of campaigns designed to focus public attention upon the welfare of children. Among these campaigns was the “ weighing and measuring test.” During the periocf devoted to this test great numbers of children—for the most part under 6 years of a g e in all parts of the United States, were weighed and measured. Record blanks were furnished by the bureau, and when the children were brought for examination entries were made of height, weight, age, sex, and race, besides particulars of country of birth of father j and mother, and physical condition of the child. As a result of this campaign the bureau received over 2,000,000 j records, and was thus in possession of a larger mass of anthropo metric material relating to children of these ages than was ever i before available. Consultations were held with, anthropologists, \ statisticians, and pediatrists, and plans of tabulation were prepared ■ in accordance with, recommendations made by the authorities . consulted. . „ . , , . , , ,, A careful selection was made of approximately one-twelltn ot tne cards which had been received. The basis of selection was fourfold:' (1) The record card must have been signed by a physician; (2) no serious defects should have been noted; (3) the child must have been weighed and measured without clothing, as verified by the physician signing the card; and (4) all essential items must have been answered. - . , On the basis of these selected records, tables have been made showing average weights and heights for children of different ages and average weights for children of different heights. They are based upon measurements of 167,024 white children. The children included in the tabulation were 70 per cent of native parentage; 6 per cent with one parent native and one foreign born, 4 per cent oi British, and. Irish, parentage) and the remainder of Scandinavian, Italian, and other racial stocks. They represent children from every part of the country. The averages lor white children of native parentage agree very closely with these averages for all white children. . Table 1 shows average heights and weights of boys and girls Irom birth to 72 months of age, and Table 2 shows average weights ot boys and girls for different heights from 20 to 47 inches. These averages represent, so far as the original material permits, averages based upon children without defects or diseases. 49428°—21 https://fraser.stlouisfed.org Federal Reserve Bank of St. Louis . . . . , .
