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 the CPI for the Los Angeles area monthly, the San Francisco area bimonthly, San Diego semiannually, 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 Los Angeles CPI and San Francisco CPI. The California CPI formula was developed by the California Department of Industrial Relations. How to use CPI data.
