Consumer Price Indexes
|
|
Retirement benefit cost-of-living adjustments (COLAs)
are determined by the consumer price indexes calculated
and maintained by the U.S. Bureau of Labor Statistics.
The Consumer Price Index (CPI) is a measure of the
changes in prices of all goods and services purchased
for consumption by urban households.
We update this page in early March of each year.
Separate indexes are produced for regional urban areas
and the nation as a whole. Indexes are further
specified "all urban consumers" (CPI-U), and "urban
wage-earners and clerical workers" (CPI-W). The
indexes below are used to determine annual benefit
increases for Plan 2 and 3, the Washington State Patrol,
and a handful of Plan 1 retirees who selected a benefit
payment option that provides a Plan 2-style COLA.
