                   Consumer Price Index - June 2012

 The Consumer Price Index for All Urban Consumers (CPI-U) was
 unchanged in June on a seasonally adjusted basis, the U.S. Bureau of
 Labor Statistics reported today. Over the last 12 months, the all
 items index increased 1.7 percent before seasonal adjustment.
 
 The energy index continued to fall in June, but its decline was
 offset by increases in the indexes for food and all items less food
 and energy. The energy index fell 1.4 percent as the gasoline index
 declined for the third month in a row; other energy indexes were
 mixed. The food index rose 0.2 percent after being unchanged last
 month as the index for food at home turned up in June.
 
 The index for all items less food and energy rose 0.2 percent in
 June, the fourth consecutive such increase. The shelter index posted
 its smallest increase since September, the index for used cars and
 trucks was unchanged after a series of increases, and the index for
 airline fares declined. However, the index for medical care posted
 its largest increase since 2010 and the indexes for apparel and
 recreation both rose substantially in June.
 
 The 12-month change in the index for all items was 1.7 percent in
 June, the same figure as in May. The energy index declined 3.9
 percent over the last 12 months, while the food index rose 2.7
 percent. The index for all items less food and energy rose 2.2
 percent for the 12 months ending June, a slight decline from the 2.3
 percent figure in May.

 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 29 percent of the total population and (2) the
 CPI for All Urban Consumers (CPI-U) and the Chained CPI for All Urban
 Consumers (C-CPI-U), which cover approximately 88 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 2011".  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/cpivar2011.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 2007 through December 2011 were replaced in January
 2012.  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: 38 of the 82 components are not
 seasonally adjusted for 2012.
 
 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 2012, BLS adjusted 31
 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.

 series and explanations, please refer to the article "Intervention
 Analysis Seasonal Adjustment", located on our website at
