Consumer Price Index
The Consumer Price Index (CPI) measures price changes in goods and services purchased by urban consumers. The all urban consumer (CPI-U) represents the spending patterns of the majority of the population which includes professionals, the self-employed, the poor, the unemployed, and retired people, as well as urban wage earners and clerical workers (CPI-W). The U.S. Bureau of Labor Statistics (BLS) compiles and publishes the CPI for the Los Angeles area monthly, the Riverside area bimonthly, San Diego county bimonthly, the San Francisco area bimonthly, and the nation each month. A California CPI is calculated by the California Department of Finance as a population-weighted average of the BLS-published local area CPIs. The California CPI formula was developed by the California Department of Industrial Relations. How to use CPI data
