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
- The indexes for prescription drugs were incorrect as published for May 2016 through August 2016, which affected the U.S. All items index. Incorrect prices were used in the calculation of indexes in several local areas. A list of the series affected by the errors can be found at www.bls.gov/bls/errata/cpi-price-corrections-10182016.htm.
- 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: http://www.bls.gov/cpi/georevision2018.htm.
Next Release:
- January 2017 CPI data are scheduled to be released on February 15, 2017, at 8:30 A.M. Eastern Time.

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 2011 through December 2015, on Wednesday, February 17, 2016.
For information on seasonal adjustment in the CPI, including revised indexes, seasonal factors, methodology, and actions taken in 2015, 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".
