CONSUMER PRICE INDEX – APRIL 2011 

The Consumer Price Index for All Urban Consumers (CPI-U) increased 0.4 percent in April on a 

seasonally adjusted basis, the U.S. Bureau of Labor Statistics reported today. Over the last 12 months, 

the all items index increased 3.2 percent before seasonal adjustment. 

The energy index posted another increase in April as the gasoline index continued to rise, the latter 

accounting for almost half of the seasonally adjusted all items increase. The household energy index also 

rose, with all of its major components posting increases. The food index increased as well in April, 

though the 0.5 percent rise in the food at home index was the smallest increase this year. Within the food 

at home component, the indexes for meats, poultry, fish, and eggs, for dairy and related products, and 

for nonalcoholic beverages all posted notable increases, though the fresh vegetables index did decline 

following recent advances.

The index for all items less food and energy rose 0.2 percent in April, the third increase of that size in 

the last four months. Indexes making major contributions to that increase included those for new 

vehicles, used cars and trucks, medical care, and shelter. 

The 12-month increases of major indexes continue to climb. The all items index rose 3.2 percent for the 

12 months ending April 2011, the highest figure since October 2008. The energy index has now risen 

19.0 percent over the last 12 months, with the gasoline index up 33.1 percent. The food index has risen 

3.2 percent while the index for all items less food and energy has increased 1.3 percent; both figures 

represent increases over recent months.

Consumer Price Index Data for April 2011 

Food

The food index rose 0.4 percent in April after rising 0.8 percent in March. The food at home index, up 

1.1 percent in March, rose 0.5 percent in April. The deceleration was mainly due to the fresh vegetables 

index, which turned down in April, falling 2.7 percent after posting large increases in each of the 

previous two months. This led to the fruits and vegetables index declining 1.1 percent, the only major 

grocery store food group to decline in April. In contrast to this decline, the index for dairy and related 

products rose 1.7 percent, the index for nonalcoholic beverages advanced 1.2 percent, and the index for 

meats, poultry, fish, and eggs increased 1.1 percent. The indexes for cereals and bakery products and for 

other food at home posted smaller increases. The food at home index has risen 3.9 percent over the last 

12 months, with all major grocery store food groups increasing over the period. The index for food away 

from home rose 0.3 percent in April, the same increase as in March. 

Energy

The energy index rose 2.2 percent in April. This is the tenth increase in a row and follows advances of 

3.5 percent in March and 3.4 percent in February. The gasoline index rose 3.3 percent in April after a 5.6 

percent increase in March. (Before seasonal adjustment, gasoline prices rose 7.5 percent in April.) The 

index for household energy also increased in April, rising 0.7 percent. The fuel oil index rose 3.2 

percent, continuing a strong upward trend, while the index for electricity increased 0.2 percent. The 

index for natural gas, which declined in March, rose 1.9 percent in April. The household energy index 

has risen 1.9 percent over the last 12 months, with the fuel oil index up 35.1 percent and the electricity 

index up 0.6 percent but the index for natural gas down 1.5 percent. 

All items less food and energy 

The index for all items less food and energy rose 0.2 percent in April after increasing 0.1 percent in 

March. The shelter index, and its rent and owners’ equivalent rent components, all repeated their March 

increases of 0.1 percent. The new vehicles index rose 0.7 percent, also a repeat of its March increase, 

while the index for used cars and trucks advanced 1.2 percent in April after a 0.8 percent increase in 

March. The index for medical care, which rose 0.2 percent in March, advanced 0.4 percent in April. The 

index for medical care commodities increased 0.5 percent while the medical care services index rose 0.3 

percent. The indexes for apparel and for household furnishings and operations both turned up in April, 

each rising 0.2 percent after declining in March. The index for recreation was unchanged in April, as it 

was in March. The tobacco index declined in April, falling 0.4 percent, its largest decline since 2007. 

The index for all items less food and energy increased 1.3 percent over the last 12 months. Indexes that 

have increased over that time include airline fares (up 12.1 percent), medical care (up 2.9 percent), new 

vehicles (up 2.4 percent), and shelter (up 1.0 percent). Indexes that have declined included household 

furnishings and operations (down 0.9 percent) and recreation (down 0.4 percent).

Not seasonally adjusted CPI measures 

The Consumer Price Index for All Urban Consumers (CPI-U) increased 3.2 percent over the last 12 

months to an index level of 224.906 (1982-84=100). For the month, the index increased 0.6 percent prior 

to seasonal adjustment. 

The Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W) increased 3.6 

percent over the last 12 months to an index level of 221.743 (1982-84=100). For the month, the index 

rose 0.8 percent prior to seasonal adjustment. 

The Chained Consumer Price Index for All Urban Consumers (C-CPI-U) increased 2.9 percent over the 

last 12 months. For the month, the index increased 0.6 percent on a not seasonally adjusted basis. Please 

note that the indexes for the post-2009 period are subject to revision.

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 

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. 

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 
- 8 -

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

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.

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.
