					Rebasing of Selected Consumer Price Index Series

With the publication of April 2026 data on May 12, 2026, several CPI series will be rebased to December 
2024 = 100. When new base years are introduced, BLS recalculates each index back to the beginning of that 
series to ensure continuity. A complete list of indexes to be rebased is available at 
www.bls.gov/cpi/additional-resources/rebased-series.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 over 90 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 approximately 30 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 75 urban areas
across the country from about 6,000 housing units and approximately 22,000 retail establishments (department stores,
supermarkets, hospitals, 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 75 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
visit, telephone call, web, or app collection 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 23 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 0.04 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 0.08 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 0.12 and 0.28 percent. For the latest data, including information on how to use
the estimates of standard error, see www.bls.gov/cpi/tables/variance-estimates/home.htm. 

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  18.0/225.000 x 100 = 8.0   18.0/110.000 x 100 = 16.4

Use of Seasonally Adjusted and Unadjusted Data

The Consumer Price Index (CPI) program 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. The
factors are available at www.bls.gov/web/cpi/cpi-seasonal-factors.xlsx. For more information on data revision
scheduling, please see the Seasonal Adjustment questions and answers page at
www.bls.gov/cpi/seasonal-adjustment/questions-and-answers.htm and the Timeline of Seasonal Adjustment Methodological
Changes at www.bls.gov/cpi/seasonal-adjustment/timeline-seasonal-adjustment-methodology-changes.htm. 

How to Use Seasonally Adjusted and Unadjusted Data

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 for five years.

Intervention Analysis

The Bureau of Labor Statistics uses intervention analysis seasonal adjustment (IASA) 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 for January 2026, BLS adjusted 57 series using intervention analysis seasonal
adjustment, including selected food and beverage items, motor fuels and vehicles.

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. For January 2026, revised seasonal factors and seasonally
adjusted indexes for 2021 to 2025 were calculated and published. For series which are directly adjusted using the
Census X-13ARIMA-SEATS seasonal adjustment software, the seasonal factors for 2025 will be applied to data for 2026 to
produce the seasonally adjusted 2026 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. For 2026, 36 of the 81 components of the U.S. city average all items index are
not seasonally adjusted.
