Since 1975, Social Security general benefit increases have been cost-of-living adjustments or COLAs. The 1975-1982 COLAs were effective with Social Security benefits payable for June in each of those years; thereafter COLAs have been effective with benefits payable for December.
Prior to 1975, Social Security benefit increases were set by legislation.

a The COLA for December 1999 was originally determined as 2.4 percent based on CPIs published by the Bureau of Labor Statistics. Pursuant to Public Law 106-554, however, this COLA is effectively now 2.5 percent.
The first COLA, for June 1975, was based on the increase in the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W) from the second quarter of 1974 to the first quarter of 1975. The 1976-1983 COLAs were based on increases in the CPI-W from the first quarter of the prior year to the corresponding quarter of the current year in which the COLA became effective. After 1983, COLAs have been based on increases in the CPI-W from the third quarter of the prior year to the corresponding quarter of the current year in which the COLA became effective.
