Where 53583 actually covers
Sauk County holds 66.75% of the ZIP’s land area, Dane County 33.04%, and Columbia County a sliver at 0.20%, according to the Census Bureau’s ZCTA-to-county allocation data reported by City-Data. The village of Sauk City itself covers about 1.6 square miles and roughly 3,483 residents per the Census Bureau’s 2024 five-year estimate, as compiled by Census Reporter. The ZIP as a whole spans about 75 square miles, per Zip-Codes.com‘s geographic data. Most of that land is rural Sauk and Dane County territory well outside the village limits, which is why an address “in 53583” and an address “in Sauk City” are not automatically the same thing for tax, school, or voting purposes.
One landmark sits squarely inside the village core rather than the rural fringe: the original Culver’s restaurant opened on July 18, 1984, at 716 Phillips Blvd, a date and address confirmed by Culver’s own company history and by the historical marker placed at the site.
Is Sauk City, WI the same as ZIP code 53583?No. The village of Sauk City covers about 1.6 square miles. ZIP 53583 covers roughly 75 square miles across three counties, most of it rural land outside the village boundary.
Population, by the numbers
| Source / vintage | Population | Median household income |
|---|---|---|
| 2020 Decennial Census | 5,787 | not collected on the short-form census |
| Census five-year survey, 2019–2023 | 5,861 | $97,286 |
| 2010 Decennial Census | 5,747 | – |
Sourced from GreatData’s Census-sourced figures and City-Data’s ACS-based estimate. The 74-person gap between the 2020 count and the rolling survey estimate is a vintage difference: a decennial census counts every household in one fixed year, while a five-year survey averages five years of sampled responses, so the two figures were never meant to match exactly.
Why do population figures for 53583 differ between websites?Some sites use the fixed 2020 Decennial Census count (5,787), others use a rolling five-year survey estimate (5,861), and some third-party ZIP databases apply their own projections on top of either. Check which vintage a number comes from before comparing two sources.
