CONSUMER PRICE INDEX – MARCH 2011
The Consumer Price Index for All Urban Consumers (CPI-U) increased 0.5 percent in March on a
seasonally adjusted basis, the U.S. Bureau of Labor Statistics reported today. Over the last 12 months,
the all items index increased 2.7 percent before seasonal adjustment.
Gasoline and food prices continued to rise and together accounted for almost three quarters of the
seasonally adjusted all items increase in March. The gasoline index posted its ninth consecutive increase
and has now risen 14.4 percent over the last three months. The household energy index rose as well,
with advances in the fuel oil and electricity indexes more than offsetting a decline in the index for
natural gas. The food at home index continued to accelerate in March, rising 1.1 percent as all six major
grocery store food groups increased.
The index for all items less food and energy rose 0.1 percent in March, a smaller increase than in the
previous two months. The index for shelter rose slightly, as did the index for medical care. Several
transportation indexes posted significant increases, including new vehicles, used cars and trucks, and
airline fares. In contrast, the indexes for apparel and for household furnishings and operations both
declined in March.
The all items index rose 2.7 percent in the last 12 months, the largest increase since December 2009.
The energy index has now risen 15.5 percent over the last 12 months, with the gasoline index up 27.5
percent. The food index has risen 2.9 percent with the food at home index up 3.6 percent. The index for
all items less food and energy has increased 1.2 percent with the shelter index up 0.9 percent.

The food index rose 0.8 percent in March after rising 0.6 percent in February. The food at home index
increased 1.1 percent in March and has risen 2.7 percent over the past three months. All six major
grocery store food groups increased in March, with increases ranging from 0.5 percent for cereals and
bakery products to 1.9 percent for fruits and vegetables. Within the fruits and vegetables component, the
fresh vegetables index rose 4.7 percent in March after a 6.7 percent increase in February, as indexes for
potatoes, lettuce, and tomatoes all posted significant increases. The index for dairy and related products
increased 1.3 percent, while the index for meats, poultry, fish, and eggs rose 1.1 percent. The index for
nonalcoholic beverages increased 0.8 percent as the coffee index climbed 3.5 percent. Over the past 12
months, the index for food at home has risen 3.6 percent with the index for meats, poultry, fish and eggs
up 7.9 percent. The index for food away from home increased 0.3 percent in March, its largest increase
since September, and has risen 1.9 percent over the past 12 months.
Energy
The energy index rose 3.5 percent in March after increasing 3.4 percent in February. It has increased for
nine months in a row, rising 23.7 percent since June 2010. The gasoline index rose 5.6 percent in March
after a 4.7 percent increase in February. (Before seasonal adjustment, gasoline prices rose 11.7 percent
in March.) The index for household energy advanced 0.6 percent in March after a 1.3 percent increase in
February. The fuel oil index rose 6.2 percent and has increased 37.2 percent in the last six months. The
index for electricity increased 0.7 percent in March, while the index for natural gas declined 1.4 percent.
The household energy index has risen 1.2 percent over the last 12 months, with the fuel oil index up 34.0
percent and the electricity index up 1.0 percent but the index for natural gas down 5.5 percent.
All items less food and energy
The index for all items less food and energy rose 0.1 percent in March after increasing 0.2 percent in
each of the previous two months. The shelter index increased 0.1 percent for the sixth month in a row,
with rent and owners’ equivalent rent both increasing 0.1 percent in March, as they did in February.
Several transportation indexes increased in March; the new vehicles index rose 0.7 percent after a 1.0
percent increase in February, and the index for used cars and trucks rose 0.8 percent. The airline fares
index also continued to rise, increasing 1.9 percent. The medical care index increased 0.2 percent in
March after a 0.4 percent increase in February, with the medical care commodities index rising 0.5
percent and the index for medical care services advancing 0.1 percent. The recreation index was
unchanged in March after a 0.3 percent increase in February, while several indexes posted declines in
March. The apparel index fell 0.5 percent after a 0.9 percent decrease in February. The index for
household furnishings and operations turned down in March, falling 0.1 percent after rising by that
amount in February. Similarly, the index for personal care fell 0.2 percent in March after rising in each
of the previous two months.
The index for all items less food and energy increased 1.2 percent over the last 12 months. This change
is above the low of 0.6 percent in October, but is still below the 1.9 percent average over the last 10
years. The indexes for shelter, new vehicles, used cars and trucks, airline fares, and medical care are
among those that have increased over the past year; the indexes for apparel, household furnishings and
operations, and recreation have declined.

Corrections to CPI data for January and February 2011
Incorrect prices were used in the calculation of the intracity transportation index, affecting the data for
January and February 2011. The January and February news releases have been reissued with corrected
data. The corrections affect indexes in Table 7 of the release and are noted in the footnotes of that table
in this release.

Brief Explanation of the CPI
The Consumer Price Index (CPI) is a measure of the average change in prices over time of goods and
services purchased by households. The Bureau of Labor Statistics publishes CPIs for two population
groups: (1) the CPI for Urban Wage Earners and Clerical Workers (CPI-W), which covers households
of wage earners and clerical workers that comprise approximately 32 percent of the total population and
(2) the CPI for All Urban Consumers (CPI-U) and the Chained CPI for All Urban Consumers (C-CPIU), which cover approximately 87 percent of the total population and include in addition to wage
earners and clerical worker households, groups such as professional, managerial, and technical workers,
the self-employed, short-term workers, the unemployed, and retirees and others not in the labor force.
The CPIs are based on prices of food, clothing, shelter, and fuels, transportation fares, charges for
doctors’ and dentists’ services, drugs, and other goods and services that people buy for day-to-day
living. Prices are collected each month in 87 urban areas across the country from about 4,000 housing
units and approximately 26,000 retail establishments-department stores, supermarkets, hospitals, filling
stations, and other types of stores and service establishments. All taxes directly associated with the
purchase and use of items are included in the index. Prices of fuels and a few other items are obtained
every month in all 87 locations. Prices of most other commodities and services are collected every
month in the three largest geographic areas and every other month in other areas. Prices of most goods
and services are obtained by personal visits or telephone calls of the Bureau’s trained representatives.
In calculating the index, price changes for the various items in each location are averaged together with
weights, which represent their importance in the spending of the appropriate population group. Local
data are then combined to obtain a U.S. city average. For the CPI-U and CPI-W separate indexes are
also published by size of city, by region of the country, for cross-classifications of regions and
population-size classes, and for 27 local areas. Area indexes do not measure differences in the level of
prices among cities; they only measure the average change in prices for each area since the base period.
For the C-CPI-U data are issued only at the national level. It is important to note that the CPI-U and
CPI-W are considered final when released, but the C-CPI-U is issued in preliminary form and subject to
two annual revisions.
The index measures price change from a designed reference date. For the CPI-U and the CPI-W the
reference base is 1982-84 equals 100. The reference base for the C-CPI-U is December 1999 equals
100. An increase of 16.5 percent from the reference base, for example, is shown as 116.500. This
-5-

change can also be expressed in dollars as follows: the price of a base period market basket of goods
and services in the CPI has risen from $10 in 1982-84 to $11.65.

Note on Sampling Error in the Consumer Price Index
The CPI is a statistical estimate that is subject to sampling error because it is based upon a sample of
retail prices and not the complete universe of all prices. BLS calculates and publishes estimates of the
1-month, 2-month, 6-month and 12-month percent change standard errors annually, for the CPI-U.
These standard error estimates can be used to construct confidence intervals for hypothesis testing. For
example, the estimated standard error of the 1 month percent change is 0.03 percent for the U.S. All
Items Consumer Price Index. This means that if we repeatedly sample from the universe of all retail
prices using the same methodology, and estimate a percentage change for each sample, then 95% of
these estimates would be within 0.06 percent of the 1 month percentage change based on all retail prices.
For example, for a 1-month change of 0.2 percent in the All Items CPI for All Urban Consumers, we are
95 percent confident that the actual percent change based on all retail prices would fall between 0.14 and
0.26 percent. For the latest data, including information on how to use the estimates of standard error,
see “Variance Estimates for Price Changes in the Consumer Price Index, January-December 2010”.
These data are available on the CPI home page (http://www.bls.gov/cpi), or by using the following link
http://www.bls.gov/cpi/cpivar2010.pdf

Calculating Index Changes
Movements of the indexes from one month to another are usually expressed as percent changes rather
than changes in index points, because index point changes are affected by the level of the index in
relation to its base period while percent changes are not. The example below illustrates the computation
of index point and percent changes.
Percent changes for 3-month and 6-month periods are expressed as annual rates and are computed
according to the standard formula for compound growth rates. These data indicate what the percent
change would be if the current rate were maintained for a 12-month period.

A Note on Seasonally Adjusted and Unadjusted Data
Because price data are used for different purposes by different groups, the Bureau of Labor Statistics
publishes seasonally adjusted as well as unadjusted changes each month.
For analyzing general price trends in the economy, seasonally adjusted changes are usually preferred
since they eliminate the effect of changes that normally occur at the same time and in about the same
magnitude every year--such as price movements resulting from changing climatic conditions, production
cycles, model changeovers, holidays, and sales.
The unadjusted data are of primary interest to consumers concerned about the prices they actually pay.
Unadjusted data also are used extensively for escalation purposes. Many collective bargaining contract
agreements and pension plans, for example, tie compensation changes to the Consumer Price Index
before adjustment for seasonal variation.

-7-

Seasonal factors used in computing the seasonally adjusted indexes are derived by the X-12-ARIMA
Seasonal Adjustment Method. Seasonally adjusted indexes and seasonal factors are computed annually.
Each year, the last 5 years of seasonally adjusted data are revised. Data from January 2006 through
December 2010 were replaced in January 2011. Exceptions to the usual revision schedule were: the
updated seasonal data at the end of 1977 replaced data from 1967 through 1977; and, in January 2002,
dependently seasonally adjusted series were revised for January 1987-December 2001 as a result of a
change in the aggregation weights for dependently adjusted series. For further information, please see
“Aggregation of Dependently Adjusted Seasonally Adjusted Series,” in the October 2001 issue of the
CPI Detailed Report.
Effective with the publication of data from January 2006 through December 2010 in January 2011, the
Video and audio series and the Information technology, hardware and services series were changed from
independently adjusted to dependently adjusted. This resulted in an increase in the number of seasonal
components used in deriving seasonal movement of the All items and 54 other lower level aggregations,
from 73 for the publication of January 1998 through December 2005 data to 82 for the publication of
seasonally adjusted data for January 2006 and later. Each year the seasonal status of every series is
reevaluated based upon certain statistical criteria. If any of the 82 components change their seasonal
adjustment status from seasonally adjusted to not seasonally adjusted, not seasonally adjusted data will
be used in the aggregation of the dependent series for the last 5 years, but the seasonally adjusted
indexes before that period will not be changed. Note: 37 of the 82 components are not seasonally
adjusted for 2011.
Seasonally adjusted data, including the all items index levels, are subject to revision for up to five years
after their original release. For this reason, BLS advises against the use of these data in escalation
agreements.
Effective with the calculation of the seasonal factors for 1990, the Bureau of Labor Statistics has used an
enhanced seasonal adjustment procedure called Intervention Analysis Seasonal Adjustment for some
CPI series. Intervention Analysis Seasonal Adjustment allows for better estimates of seasonally
adjusted data. Extreme values and/or sharp movements which might distort the seasonal pattern are
estimated and removed from the data prior to calculation of seasonal factors. Beginning with the
calculation of seasonal factors for 1996, X-12-ARIMA software was used for Intervention Analysis
Seasonal Adjustment.
For the seasonal factors introduced in January 2011, BLS adjusted 29 series using Intervention Analysis
Seasonal Adjustment, including selected food and beverage items, motor fuels, electricity and vehicles.
For example, this procedure was used for the Motor fuel series to offset the effects of events such as
damage to oil refineries from Hurricane Katrina.
For a complete list of Intervention Analysis Seasonal Adjustment series and explanations, please refer to
the article “Intervention Analysis Seasonal Adjustment”, located on our website at
http://www.bls.gov/cpi/cpisapage.htm.

Statistics, Division of Consumer Prices and Price Indexes, Washington, DC 20212 or contact David

6 Indexes on a November 1996=100 base.
- Data not available.
NOTE: Local area indexes are byproducts of the national CPI program.
Each local index has a smaller sample size than the national index and is,
therefore, subject to substantially more sampling and other measurement
error. As a result, local area indexes show greater volatility than the national
index, although their long-term trends are similar. Therefore, the Bureau of
Labor Statistics strongly urges users to consider adopting the national
average CPI for use in their escalator clauses.
NOTE: Index applies to a month as a whole, not to any specific date.

6 Indexes on a November 1996=100 base.
- Data not available.
NOTE: Local area indexes are byproducts of the national CPI program.
Each local index has a smaller sample size than the national index and is,
therefore, subject to substantially more sampling and other measurement
error. As a result, local area indexes show greater volatility than the national
index, although their long-term trends are similar. Therefore, the Bureau of
Labor Statistics strongly urges users to consider adopting the national
average CPI for use in their escalator clauses.
NOTE: Index applies to a month as a whole, not to any specific date.
