The Consumer Price Index for All Urban Consumers (CPI-U) for Chicago-Naperville-Elgin increased 2.5 percent for the 12 months ending in November, the U.S. Bureau of Labor Statistics (BLS) reported today. Acting Regional Commissioner Bryan Droste noted that the index for all items less food and energy rose 2.3 percent over the year, and food prices advanced 2.0 percent. Energy prices rose 6.7 percent.

BLS did not collect survey data for October 2025 due to a lapse in appropriations. BLS is unable to retroactively collect these data. For a few indexes, BLS uses nonsurvey data sources instead of survey data to make the index calculations. BLS was able to retroactively acquire most of the nonsurvey data for October. Accordingly, all analysis in this release is over the year and not seasonally adjusted.

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.

The Chicago-Naperville-Elgin, IL-IN-WICore Based Statistical Area includes Cook, DeKalb, DuPage, Grundy, Kane, Kendall, Lake, McHenry, and Will Counties in Illinois; Jasper, Lake, Newton, and Porter Counties in Indiana; and Kenosha County in Wisconsin.
