 CONSUMER PRICE INDEX – JUNE 2017

 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 rose 1.6 percent.

 The energy index declined again in June, falling 1.6 percent; this offset an
 increase in the index for all items less food and energy. All the major energy
 component indexes declined, with the gasoline index falling 2.8 percent. The
 food index was unchanged in June, with the index for food at home declining
 slightly as five of the six major grocery store food group indexes decreased.  

 The index for all items less food and energy rose 0.1 percent in June, its
 third straight such increase. The shelter index continued to rise, and the
 indexes for medical care, motor vehicle insurance, education, and personal care
 also increased. The indexes for airline fares, used cars and trucks, wireless
 telephone services, and new vehicles were among the indexes that declined
 in June.  

 The all items index rose 1.6 percent for the 12 months ending June; this
 measure has been declining steadily since February, when it was 2.7 percent.
 The index for all items less food and energy rose 1.7 percent for the 12 months
 ending June, the same increase as for the 12 months ending May. The energy
 index rose 2.3 percent over the last year, while the food index increased
 0.9 percent.

 Food

 The food index was unchanged in June after rising in each of the five previous
 months. The index for food at home fell 0.1 percent, as five of the six major
 grocery store food group indexes declined. The nonalcoholic beverages index
 fell 0.6 percent, and the index for dairy and related products declined
 0.5 percent. The index for other food at home fell 0.3 percent, and the
 indexes for cereals and bakery products and for fruits and vegetables both
 fell 0.1 percent. 

 The index for meats, poultry, fish, and eggs increased 0.6 percent as the 
 index for beef rose 2.9 percent. The index for food away from home was
 unchanged in June.

 The index for food at home declined slightly over the past 12 months, falling
 0.1 percent. The indexes for meats, poultry, fish, and eggs, for cereals and
 bakery products, and for other food at home declined over the last 12 months,
 while the indexes for nonalcoholic beverages, for fruits and vegetables, and
 for dairy and related products increased over the 12-month period. The index
 for food away from home increased 2.2 percent over the past year. 


 Energy

 The energy index decreased 1.6 percent in June after falling 2.7 percent in
 May. The gasoline index continued to fall, declining 2.8 percent in June after
 a 6.4-percent decrease in May. (Before seasonal adjustment, gasoline prices
 decreased 1.7 percent in June.) The other energy component indexes also
 declined in June; the electricity index fell 0.6 percent, and the index for
 natural gas declined 0.2 percent. 

 The gasoline index fell 0.4 percent over the past 12 months, while the other
 major energy components rose over the span. The index for natural gas increased
 12.8 percent over the last year, and the electricity index advanced 2.5 percent. 


 All items less food and energy

 The index for all items less food and energy increased 0.1 percent in June, the
 same increase as in April and May. The shelter index rose 0.2 percent in June,
 with the indexes for rent and owners' equivalent rent both rising 0.3 percent.
 The index for lodging away from home fell 1.9 percent in June after rising in
 May. The medical care index rose 0.4 percent in June, its largest increase since
 last August; however, major medical care component indexes were mixed. The index
 for prescription drugs increased 1.0 percent and the hospital services index
 rose 0.9 percent, but the index for physicians' services fell 0.4 percent. The
 index for motor vehicle insurance continued to rise, increasing 1.0 percent in
 June, and the education index and personal care index both rose 0.3 percent.

 Several indexes declined in June, including the index for airline fares, which
 fell 2.7 percent, the same decline as in May. The index for used cars and trucks
 fell 0.7 percent, its sixth consecutive decline. The index for wireless telephone
 services also continued to fall, decreasing 0.8 percent in June. The new vehicles
 index fell 0.3 percent, and the indexes for household furnishings and operations,
 recreation, apparel, and tobacco also declined in June.

 The index for all items less food and energy rose 1.7 percent over the past 12
 months. The shelter index rose 3.3 percent over the year, and the index for
 medical care rose 2.7 percent. The indexes for used cars and trucks, airline
 fares, apparel, and household furnishings and operations are among those that
 declined over the past year. 

 Not seasonally adjusted CPI measures

 The Consumer Price Index for All Urban Consumers (CPI-U) increased 1.6 percent
 over the last 12 months to an index level of 244.955 (1982-84=100). For the
 month, the index rose 0.1 percent prior to seasonal adjustment.

 The Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W)
 increased 1.5 percent over the last 12 months to an index level of 238.813
 (1982-84=100). For the month, the index increased 0.1 percent prior to seasonal
 adjustment.

 The Chained Consumer Price Index for All Urban Consumers (C-CPI-U) increased
 1.5 percent over the last 12 months. For the month, the index rose 0.1 percent
 on a not seasonally adjusted basis. Please note that the indexes for the past
 10 to 12 months are subject to revision. 

 The Consumer Price Index for July 2017 is scheduled to be released on Friday,
 August 11, 2017, at 8:30 a.m. (EDT).

                   Consumer Price Index Geographic Revision for 2018

 In January 2018, BLS will introduce a new geographic area sample for the Consumer 
 Price Index (CPI). The 2018 revision utilizes the 2010 Decennial Census and 
 incorporates an updated area sample design, changes the frequency of publication 
 for several local area indexes, and establishes some new local area and aggregate 
 indexes. The first indexes using the new structure will be published in February 
 2018. Additional information on the geographic revision is available at: 
 www.bls.gov/cpi/georevision2018.htm. 
 ---------------------------------------------------------------------------------- 		


 Technical Note

 Brief Explanation of the CPI

 The Consumer Price Index (CPI) measures the change in prices paid by consumers for
 goods and services. The CPI reflects spending patterns for each of two population
 groups: all urban consumers and urban wage earners and clerical workers. The all
 urban consumer group represents about 89 percent of the total U.S. population.
 It is based on the expenditures of almost all residents of urban or metropolitan
 areas, including professionals, the self-employed, the poor, the unemployed, and
 retired people, as well as urban wage earners and clerical workers. Not included
 in the CPI are the spending patterns of people living in rural nonmetropolitan
 areas, farming families, people in the Armed Forces, and those in institutions,
 such as prisons and mental hospitals. Consumer inflation for all urban consumers is
 measured by two indexes, namely, the Consumer Price Index for All Urban Consumers
 (CPI-U) and the Chained Consumer Price Index for All Urban Consumers (C-CPI-U). 

 The Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W) is
 based on the expenditures of households included in the CPI-U definition that meet
 two requirements: more than one-half of the household's income must come from
 clerical or wage occupations, and at least one of the household's earners must have
 been employed for at least 37 weeks during the previous 12 months. The CPI-W
 population represents about 28 percent of the total U.S. population and is a subset
 of the CPI-U population.

 The CPIs are based on prices of food, clothing, shelter, fuels, transportation,
 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 6,000 housing units and approximately 24,000 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 by the Bureau’s trained representatives.

 In calculating the index, price changes for the various items in each location are
 aggregated using 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 selected 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. The CPI-U and CPI-W are considered final when released, but
 the C-CPI-U is issued in preliminary form and subject to three subsequent quarterly
 revisions. 

 The index measures price change from a designed reference date. For most of 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 7 percent from the reference base,
 for example, is shown as 107.000. Alternatively, that relationship can also be
 expressed as the price of a base period market basket of goods and services rising
 from $100 to $107. 


 Sampling Error in the CPI

 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 CPI. 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 percent of these estimates will 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-U, 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 www.bls.gov/cpi/cpivar2016.pdf. 

 Calculating Index Changes

 Movements of the indexes from 1 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
 following table shows an example of using index values to calculate percent changes:

                                         
				  Item A		 Item B                      Item C

 Year  I                         112.500               	 225.000                    110.000
 Year II		         121.500         	 243.000                    128.000 
 Change in index points            9.000            	  18.000                     18.000
 Percent change  9.0/112.500 x 100 = 8.0  8.0/225.000 x 100 = 8.0 18.0/110.000 x 100 = 16.4

 Use of Seasonally Adjusted and Unadjusted Data

 The Consumer Price Index (CPI) produces both unadjusted and seasonally adjusted data.
 Seasonally adjusted data are computed using seasonal factors derived by the X-13ARIMA-SEATS
 seasonal adjustment method. These factors are updated each February, and the new factors are
 used to revise the previous 5 years of seasonally adjusted data. For more information on data
 revision scheduling, please see the Fact Sheet on Seasonal Adjustment at
 www.bls.gov/cpi/cpisaqanda.htm and the Timeline of Seasonal Adjustment Methodological Changes
 at www.bls.gov/cpi/cpiseastimeline.htm. 

 For analyzing short-term 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 weather events,
 production cycles, model changeovers, holidays, and sales. This allows data users to focus on
 changes that are not typical for the time of year. The unadjusted data are of primary interest
 to consumers concerned about the prices they actually pay. Unadjusted data are also 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. BLS advises against the use of seasonally adjusted data in escalation
 agreements because seasonally adjusted series are revised annually.

 Intervention Analysis

 The Bureau of Labor Statistics uses intervention analysis seasonal adjustment for some CPI series.
 Sometimes extreme values or sharp movements can distort the underlying seasonal pattern of price
 change. Intervention analysis seasonal adjustment is a process by which the distortions caused by
 such unusual events are estimated and removed from the data prior to calculation of seasonal
 factors. The resulting seasonal factors, which more accurately represent the seasonal pattern, are
 then applied to the unadjusted data. 

 For example, this procedure was used for the motor fuel series to offset the effects of the 2009
 return to normal pricing after the worldwide economic downturn in 2008. Retaining this outlier data
 during seasonal factor calculation would distort the computation of the seasonal portion of the
 time series data for motor fuel, so it was estimated and removed from the data prior to seasonal
 adjustment. Following that, seasonal factors were calculated based on this “prior adjusted” data.
 These seasonal factors represent a clearer picture of the seasonal pattern in the data. The last
 step is for motor fuel seasonal factors to be applied to the unadjusted data.

 For the seasonal factors introduced in January 2017, BLS adjusted 40 series using intervention
 analysis seasonal adjustment, including selected food and beverage items, motor fuels, and natural
 gas. 

 Revision of Seasonally Adjusted Indexes

 Seasonally adjusted data, including the U.S. city average all items index levels, are subject to
 revision for up to 5 years after their original release. Every year, economists in the CPI
 calculate new seasonal factors for seasonally adjusted series and apply them to the last 5 years
 of data. Seasonally adjusted indexes beyond the last 5 years of data are considered to be final
 and not subject to revision. In January 2017, revised seasonal factors and seasonally adjusted
 indexes for 2012 to 2016 were calculated and published. For series which are directly adjusted
 using the Census X-13ARIMA-SEATS seasonal adjustment software, the seasonal factors for 2016 will
 be applied to data for 2017 to produce the seasonally adjusted 2017 indexes. Series which are
 indirectly seasonally adjusted by summing seasonally adjusted component series have seasonal
 factors which are derived and are therefore not available in advance. 

 Determining Seasonal Status

 Each year the seasonal status of every series is reevaluated based upon certain statistical
 criteria. Using these criteria, BLS economists determine whether a series should change its status
 from "not seasonally adjusted" to "seasonally adjusted", or vice versa. If any of the 81 components
 of the U.S. city average all items index 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. Twenty-seven of the 81 components of the U.S. city average all items index are
 not seasonally adjusted for 2017.
