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 2003 through December 2007, on Friday, February 15, 2008.
For information on seasonal adjustment in the CPI, including revised indexes, seasonal factors, methodology, and actions taken in 2007, see our page on seasonal adjustment.
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".
Soon after the publication of September CPI data on October 17th, 2007, the Social Security Administration (SSA) announced the annual increase in its benefit payments for the coming year. This change will mean automatic increases in payments from Social Security's Old-Age, Survivors, and Disability Insurance (OASDI) and Supplemental Security Income (SSI) programs. The increase will be effective with December 2007 payments received in January 2008. Specific information on the size of the increase is available on the SSA website at http://www.ssa.gov/OACT/COLA/colasummary.html.
