That puts Chicago-Naperville-Elgin 6.9% more expensive than Milwaukee-Waukesha on a blended basket of goods, services, and rents. The raw index gap of 6.7 points matters more than the headline comparison because it flows directly into salary-equivalent math that families use for relocation, job offers, and remote-work arbitrage decisions.

Inside the breakdown, Milwaukee-Waukesha indexes goods at 93.8, services at 91.6, and rents at 97.1, while Chicago-Naperville-Elgin comes in at 107.3, 83.6, and 112.0 on the same three categories. The rent line carries the largest weight in the BEA methodology, so a metro with a higher rent index almost always ends up more expensive overall - Chicago-Naperville-Elgin carries the heavier rent load here, and that tends to dominate household budget experience on the ground.

In salary terms, a $100,000 income in Milwaukee-Waukesha has the same purchasing power as $106,868 in Chicago-Naperville-Elgin based on these indexes. The two metros serve populations of roughly 1,566,361 (Milwaukee-Waukesha) and 9,359,555 (Chicago-Naperville-Elgin), and median household incomes are $76,404 versus $88,850 respectively - so the right way to read this comparison is never the index alone, but the ratio of your expected local salary to the rent and services mix. For any serious relocation or remote-work decision, pair this BEA comparison with BLS occupation-specific wage data, HUD Fair Market Rent tables, and state tax treatment before committing.
