Is Iowa County's population growing?
- Population, July 1, 202416,423
- Census 2020 base population16,660

- Total net migration, 202448
- Cumulative net domestic migration, 2021 to 2024-118
- Rank by growth among US county-equivalents2332nd of 3,144
The county has lost 1.42 percent of its population since the 2020 census base. Deaths exceeded births in 2024 and the population still grew, so all of the growth came from people moving in. A market held up by migration is more sensitive to a change in relative cost than one growing from household formation.

The county's own community in the status book, unincorporated Iowa County (community 190878), participates in the National Flood Insurance Program and carries no Community Rating System class, so no CRS premium discount applies there. The EPA places Iowa County in radon zone 1, a predicted average indoor radon screening level greater than 4 pCi/L. The zone is a screening prediction for the county and does not substitute for a test at an address. 100.0 percent of the county's listed communities participate in the National Flood Insurance Program, per Federal Emergency Management Agency, NFIP Community Status Book (OpenFEMA), as of 2026-09-26.
