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 .

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 ".
