Harald KliemsThe latest US Census Bureau 2025 county-level population estimates are out. Some quick charts: In Wisconsin, Dane County continues its relatively steady growth, adding about 4000 people compared to the previous year.
Looking at the largest counties by population in Wisconsin, Milwaukee county population declined, Dane, Waukesha, Racine went up modestly, and the other counties appear relatively stable.
Looking at growth/decline in population more explicitly, Dane County had the highest absolute growth between 2020 and 2025; Milwaukee had the greatest population loss (but remains by far the most populous county in the state).
