Wisconsin County Population — 2025 PEP

July 1, 2025 resident population estimates for 72 counties. State total (sum of these county estimates): 5,972,787 persons.

Separate 2025 TIGER/Line county boundaries validate county identity; these are not ACS 2024 survey estimates.

Official Vintage 2025 county identities and unsimplified TIGER coordinates; separate-period ACS housing is joined only by exact full GEOID. Original 2020 counts require separately evidenced compatible geography; incompatible observations remain null with reasons. The revised April estimates base is not an original census count; no boundary allocation is invented.

2025 Census PEP county estimates, 2020–2025 series; counts are persons, migration counts are persons, published rates are per 1,000, and unavailable values remain null (not zero). 2020 rates are unavailable for the partial-year interval. County totals and characteristics are verified against the pinned raw Census CSV receipts and independent 2025 county geometry.

County population trend · 2020–2025

Resident population (persons), not ACS housing. April 1, 2020 estimates base is distinct from the July 1, 2020 estimate. The April–July 2020 change is partial-year; the July 2020–July 2021 interval is the first July-to-July comparison. No 2020 annual rate is shown. Missing observations are unavailable, never zero.

Showing Milwaukee County (GEOID 55079). Select a county on the map or in the rankings table to update this trend.

Horizontal axis: year (2020–2025); vertical axis: resident population (persons). The 2020 base is a separate April 1 observation; July 1 estimates run from 2020 through 2025.

County population and median home value · different vintages

Each point pairs a county’s PEP July 1, 2025 resident population (persons) with its ACS 2024 5-year median owner-occupied home value (B25077, U.S. dollars). These are different reference periods and different statistical programs. This descriptive comparison does not imply causality or matched vintages. Suppressed, missing or invalid ACS estimates are unavailable, not zero and not plotted. A valid zero remains zero.
