Housing Vacancy Rate by Zip Code (ZCTA5) — Illinois

NOTE: Gray indicates insufficient data or a suppressed estimate.

The southern tip of Illinois exhibits notably elevated vacancy rates, with many zip codes exceeding 20–30%, consistent with long-term population decline in the Cairo and Shawnee National Forest region. The Chicago metropolitan area in the northeast displays stark internal contrasts, with some suburban zip codes registering near-zero vacancy alongside pockets of significantly higher rates, likely corresponding to areas of urban disinvestment on the city's south and west sides. Central Illinois generally clusters in the 8–12% range, though scattered rural zip codes with small housing stocks push noticeably higher, particularly along the western border near the Mississippi River corridor.
