The Consumer Price Indexes (CPI) program produces monthly data on changes in the prices paid by urban consumers for a representative basket of goods and services.

Announcements

  • Change in formula for calculation of index for prescription drugs
    Effective with release of data for January 2016, an arithmetic mean (Laspeyres) formula will replace the geometric mean formula in the calculation of the elementary indexes in the CPI-U, CPI-W, and C-CPI-U for prescription drugs. The Laspeyres formula at the elementary index level is more appropriate for use in categories in which substitution by the consumer in response to price change is difficult or unrealistic. A description of the 1999 adoption of the geometric mean formula for many elementary indexes is available at http://www.bls.gov/mlr/1998/10/art1full.pdf.
  • NEW Comparison of BLS Price and Spending Measures (HTML)
  • New Estimation System
    Effective with the release of the January 2015 CPI on February 26, 2015, the Bureau of Labor Statistics will utilize a new estimation system for the Consumer Price Index. The new estimation system, the first major improvement to the existing system in over 25 years, is a redesigned, state-of-the-art system with improved flexibility and review capabilities. For more information on this new system, please see http://www.bls.gov/cpi/cpinewest.htm.
  • Chained Consumer Price Index to be Revised Quarterly
    Effective with the release of CPI data for January 2015 on February 26, 2015, the Bureau of Labor Statistics will begin quarterly revisions of the Chained Consumer Price Index for All Urban Consumers (C-CPI-U). In addition, a Constant Elasticity of Substitution (CES) formula will replace the geometric mean formula for the calculation of Initial and Interim C-CPI-U indexes. For additional information, please see http://www.bls.gov/cpi/cpiccpi.htm.
  • Background documents on the Chained Consumer Price Index are available from http://www.bls.gov/cpi/superlink.htm

  • Reconciliation Between the CPI and PCE Price Index. The Bureau of Labor Statistics and the Bureau of Economic Analysis (BEA) undertook a joint project to detail and quantify the differences between the Consumer Price Index for All Urban Consumers (CPI-U) and the Personal Consumption Expenditures (PCE) Chain-type Price Index. A paper summarizing these differences can be found on the BEA website at http://www.bea.gov/papers/pdf/cpi_pce.pdf. The latest reconciliation tables can be found at http://www.bea.gov/national/consumer_spending.htm.
  • The Bureau of Economic Analysis (BEA) produces regional price parities (RPPs). RPPs measure the differences in the price levels of goods and services across states and metropolitan areas for a given year. RPPs are expressed as a percentage of the overall national price level for each year, which is equal to 100.0. These data, which are the products of BEA and not BLS, can be found at https://www.bea.gov/newsreleases/regional/rpp/rpp_newsrelease.htm.

Revised Seasonal Indexes

UPDATED Each year with the release of the January CPI, seasonal adjustment factors are recalculated to reflect price movements from the just-completed calendar year. This routine annual recalculation may result in revisions to seasonally adjusted indexes for the previous 5 years. BLS made available recalculated seasonally adjusted indexes, as well as recalculated seasonal adjustment factors, for the period January 2010 through December 2014, on Friday, February 20, 2015.

For information on seasonal adjustment in the CPI, including revised indexes, seasonal factors, methodology, and actions taken in 2014, see our page on seasonal adjustment.

Social Security COLA

Soon after the publication of September CPI data each October, the Social Security Administration (SSA) announces the annual change in its benefit payments for the coming year for Social Security's Old-Age, Survivors, and Disability Insurance (OASDI) and Supplemental Security Income (SSI) programs. Specific information on how the Social Security Administration uses the CPI to determine cost-of-living adjustments can be found at http://www.ssa.gov/OACT/COLA/colasummary.html.

CPI Published Numbers

Effective with the release in February 2007 of the January 2007 Consumer Price Index (CPI), the Bureau of Labor Statistics (BLS) began to publish its consumer price indexes rounded to three decimal places. Percent changes will be calculated from the three decimal place indexes. Those percent changes will continue to be published to one decimal place. For additional information, please see "Publishing Consumer Price Indexes to Three Decimal Places: Questions and Answers".
