Social Security COLA Soon after the publication of September CPI data on October 15, 2009, the Social Security Administration (SSA) announced 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/latestCOLA.html.

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 2005 through December 2009, on Wednesday, February 17, 2010.

For information on seasonal adjustment in the CPI, including revised indexes, seasonal factors, methodology, and actions taken in 2009, see our page on seasonal adjustment.

Expenditure Weight Update
Effective with the January 2010 release the Bureau of Labor Statistics (BLS) has updated the consumption expenditure weights in the Consumer Price Index for All Urban Consumers (CPI-U) and Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W) to the 2007-08 period. The updated expenditure weights for these indexes replace the 2005-2006 weights that were introduced effective with the January 2008 CPI release. As originally announced by BLS in December 1998, CPI expenditure weights will continue to be updated at two year intervals subsequent to the 2010 updating.

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".
