Publication updates and changes
In accordance with annual practice, relative importance weights have been updated and are available online in the CPI Supplemental Table of Contents.
Effective with the January 2025 data release, several indexes and average price series were discontinued. More information is available on the CPI discontinued series page. Direct any inquiries to the CPI office using one of the CPI contact information options listed online.
Technical Note
The Consumer Price Index (CPI) is a measure of the average change in prices over time in a fixed market basket of goods and services. The Consumer Price Index for Los Angeles is published monthly. The set of components and sub-aggregates published for regional and metropolitan indexes is more limited than at the U.S. city average level; these indexes are byproducts of the national CPI program. Each local index has a much smaller sample size than the national or regional indexes and is, therefore, subject to substantially more sampling and other measurement error. As a result, local-area indexes are more volatile than the national or regional indexes. In addition, local indexes are not adjusted for seasonal influences. NOTE: Area indexes do not measure differences in the level of prices between cities; they only measure the average change in prices for each area since the base period.
A full all-items data series history for the original index value and for 1-month, 2-month, 3-month, 6-month, and 12-month percent changes can be accessed via BLS data query tools. A direct link to the all-items series is provided in Table 1 of this release under historical data.
The Los Angeles-Long Beach-Anaheim, CA Core Based Statistical Area includes Los Angeles and Orange Counties in California.
Refer to the national CPI news release technical note or the Handbook of Methods for more information.
