The May 2025 Consumer Price Index for the Chicago-Naperville-Elgin area is scheduled to be released on Wednesday, June 11, 2025.

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 Chicago 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.

Percent changes for all-items data previously found in Table A of this release can be accessed in Chart 1 for this release and its attendant data table. 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.
