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 the West region 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.

The West region covered in this release is comprised of the following thirteen states: Alaska, Arizona, California, Colorado, Hawaii, Idaho, Montana, Nevada, New Mexico, Oregon, Utah, Washington, and Wyoming.

Refer to the national CPI news release technical note or the Handbook of Methods for more information.
