Consumer Price Index - September 2011

The Consumer Price Index for All Urban Consumers (CPI-U) increased
 0.3 percent in September on a seasonally adjusted basis, the U.S.
 Bureau of Labor Statistics reported today. Over the last 12 months,
 the all items index increased 3.9 percent before seasonal adjustment.
 
 Increases in energy and food indexes were the main cause of the
 seasonally adjusted all items increase. The gasoline index continued
 to rise, and indexes for electricity and natural gas increased as
 well. Broad increases in food indexes also continued in September,
 with the food at home index rising 0.6 percent for the third month in
 a row and no major grocery store food group indexes declining.
 
 The index for all items less food and energy increased 0.1 percent in
 September, its smallest increase since March. The index for apparel
 declined in September after a series of sharp increases, and the
 indexes for used cars and recreation turned down as well. The indexes
 for new vehicles and household furnishings and operations were both
 flat. The shelter index rose, but posted its smallest increase since
 April, while the indexes for medical care, airline fares, and tobacco
 all increased.
 
 The 12-month change in the all items index, which was 3.8 percent in
 August, edged up to 3.9 percent in September. The 12-month change for
 all items less food and energy remained at 2.0 percent for the second
 straight month. The energy index has risen 19.3 percent over the last
 year, while the food index has increased 4.7 percent.

 Consumer Price Index Data for September 2011
 
 Food
 
 The food index, which rose 0.5 percent in August, increased 0.4
 percent in September. The index for food at home repeated its July
 and August increase of 0.6 percent. The index for nonalcoholic
 beverages was unchanged, while the remaining major grocery store food
 groups all posted increases. The dairy and related products index
 rose the most, increasing 1.2 percent, followed by 0.9 percent
 increases in both the cereals and bakery products index and the
 fruits and vegetables index. Within the latter group, the indexes for
 apples and tomatoes both posted significant increases. The index for
 meats, poultry, fish, and eggs rose 0.4 percent as the index for eggs
 rose sharply, and the index for other food at home rose 0.6 percent.
 The food at home index has now risen 6.3 percent over the past 12
 months with the dairy index up 10.2 percent over that period. After
 rising 0.4 percent in August, the index for food away from home
 increased 0.2 percent in September and has risen 2.6 percent over the
 last 12 months.
 
 
 Energy
 
 The energy index rose 2.0 percent in September after a 1.2 percent
 increase in August. The gasoline index, which was up 1.9 percent in
 August, rose 2.9 percent in September. (Before seasonal adjustment,
 gasoline prices fell 0.7 percent in September.) Over the past 12
 months, the gasoline index has increased 33.3 percent. The household
 energy index also rose in September, advancing 0.7 percent after a
 0.4 percent increase in August. The electricity index advanced 0.7
 percent while index for natural gas rose 0.8 percent; the fuel oil
 index declined 0.7 percent. Over the past year, the household energy
 index has increased 3.7 percent. The electricity index has risen 2.7
 percent and the index for natural gas has increased 0.2 percent,
 while the fuel oil index has risen sharply, increasing 33.4 percent.
 
 
 All items less food and energy
 
 The index for all items less food and energy increased 0.1 percent in
 September, a deceleration from recent months. Several factors
 contributed to the smaller increase in September. The apparel index,
 which had risen over one percent for four months in a row, declined
 1.1 percent in September. The index for used cars and trucks also
 turned down, falling 0.6 percent after a long series of increases,
 and the recreation index declined 0.1 percent after rising in August.
 The shelter index decelerated, increasing 0.1 percent in September
 following a 0.3 percent increase in July and a 0.2 percent increase
 in August. The rent index increased 0.2 percent while the index for
 owners' equivalent rent increased 0.1 percent and the lodging away
 from home index declined 0.7 percent. The index for household
 furnishings and operations, which rose 0.3 percent in August, was
 unchanged in September, and the index for new vehicles was unchanged
 for the third month in a row. In contrast the medical care index
 continued to increase, rising 0.2 percent for the fifth month in a
 row. The indexes for airline fares, tobacco, and personal care all
 increased as well.
 
 After increasing steadily through most of the year, the 12-month
 change in the index for all items less food and energy remained at
 2.0 percent for the second month in a row. The shelter index has
 increased 1.7 percent over the last 12 months. The index for medical
 care has risen 2.8 percent while the apparel index has increased 3.5
 percent. The new vehicles index has increased 3.6 percent and the
 index for used cars and trucks has increased 5.1 percent.
 
 Not seasonally adjusted CPI measures
 
 The Consumer Price Index for All Urban Consumers (CPI-U) increased
 3.9 percent over the last 12 months to an index level of 226.889
 (1982-84=100). For the month, the index increased 0.2 percent prior
 to seasonal adjustment.
 
 The Consumer Price Index for Urban Wage Earners and Clerical Workers
 (CPI-W) increased 4.4 percent over the last 12 months to an index
 level of 223.688 (1982-84=100). For the month, the index increased
 0.2 percent prior to seasonal adjustment.
 
 The Chained Consumer Price Index for All Urban Consumers (C-CPI-U)
 increased 3.7 percent over the last 12 months. For the month, the
 index increased 0.1 percent on a not seasonally adjusted basis.
 Please note that the indexes for the post-2009 period are subject to
 revision.
 
 The Consumer Price Index for October 2011 is scheduled to be released
 on Wednesday, November 16, 2011, at 8:30 a.m. (EST).
 
 


 





 Redesigning the Consumer Price Index (CPI) News Release Tables
 
 In August 2009, the Bureau of Labor Statistics (BLS) restructured the
 text of the CPI news release to focus on the price movements of three
 broad expenditure categories; namely Food, Energy, and All items less
 food and energy. Table A within the CPI news release text was also
 updated in August 2009 to reflect this new structure. Before August
 2009, the text of the CPI news release had focused on eight CPI
 'major groups' (Food and beverages; Housing; Apparel; Transportation;
 Medical care; Recreation; Education and communication; and Other
 goods and services).
 
 While the text of the CPI news release was restructured in 2009,
 seven additional CPI news release tables continued to be published
 using the eight major groups. BLS is redesigning these news release
 tables, to reflect the focus on Food, Energy, and All items less food
 and energy. Within these three broad categories, CPI item series will
 be further divided into commodities and services.
 
 A mock-up of the new CPI news release tables can be found at
 http://beta.bls.gov/cpi/redesigned_cpi_tables/cpiprmockup.htm.
 Comments or questions about these new tables can be forwarded to
 cpi_info@bls.gov. The public comment period runs through October 31,
 2011.
 
 Beyond the redesign in the structure of the CPI news release tables,
 several other improvements to these tables have been made:
 
 The new Table 1 gives a summary of the index series which typically
 contribute to changes in the Consumer Price Index for All Urban
 Consumers (CPI-U).
 
 The new Table 2 will show the full publication stub using the new
 structure for the CPI-U, including 11 new items series that were
 created to augment the redesign in the publication structure.
 
 Table 3 will show aggregate item series (e.g., Transportation) that
 do not fall under the Food, Energy, and All items less food and
 energy structure.
 
 Table 4 will show the All items indexes at the local, regional, and
 city-size class levels. Table 5 will show the Chained Consumer Price
 Index for All Urban Consumers (C-CPI-U), and presents a history of
 annual percentage changes in the C-CPI-U compared to the CPI-U.
 
 Table 6 will focus on 1-month seasonally adjusted changes in the CPI-
 U, while table 7 will focus on 12-month not seasonally adjusted
 changes. Tables 6 and 7 will present three additional pieces of data
 to help users better interpret index changes. First, these tables
 will show the effect each item has on the price change for All items.
 For example, if the effect of food is 0.4, and the index for All
 items increased 1.2 percent, it can be said that increases in food
 prices accounted for 0.4 / 1.2, or 33.3 percent, of the increase in
 overall prices for that period. Said another way, had food prices
 been unchanged, the All items index only would have increased 0.8
 percent (or 1.2 percent for All items, minus the 0.4 effect for
 Food). Effects can be negative as well. For example, if the effect of
 food was a negative 0.1, and the All items index rose 0.5 percent,
 the All items index actually would have been 0.1 percent higher (or
 0.6 percent) had food prices been unchanged.
 
 Second, standard errors for percent changes will be shown on tables 6
 and 7. Confidence intervals for statistics can be created using
 standard errors; e.g., roughly 95% confidence intervals can be
 constructed using two standard errors. For example, if an item
 increased 3.7 percent, and its standard error was 0.6 percent, the
 95% confidence interval for that price change can be said to be 3.7
 percent plus or minus two standard errors, or 3.7 percent plus or
 minus 1.2 percent.
 
 Each item series in tables 6 and 7 will show the last time that item
 had a price change as large (or as small) as the percent change
 published that period. For example, if bananas rose 3.7 percent, and
 that was its largest increase since November 2007, that would be
 noted in the new tables.
 
 In addition, most of the existing tables show the relative
 importance, or weight, of each item category as of the previous
 December. The relative importance columns in the new tables will be
 improved in that they will be updated monthly to reflect the change
 in relative prices over time.
 
 Finally, there will no longer be any news release tables that focus
 on the Consumer Price Index for Urban Wage Earners and Clerical
 Workers (CPI-W). That said, the CPI-W All items index level and
 percent changes will still be noted in the text of the news 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-CPI-U), 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 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.
