Method
How it was counted.
Source: Wisconsin Statewide Parcel Map (Wisconsin State Cartographer's Office) (sco.wisc.edu), each county's own parcel and tax roll data, compiled into one statewide layer. Dodge, Vilas and Polk counties' records come from each county's own parcel layer. Counted 2026-10-06 with Tracer’s Request Data filters, government owners and mailing addresses abroad left out.
A complete record has an owner name, a property address that starts with a house number (a rural grid number like N9132 or W156N8480 counts), and a mailing street with a 5-digit ZIP. Out-of-state reads the mailing ZIP. Company owners are a text match on the owner name (LLC, INC, CORP, LP, TRUST, PROPERTIES, HOLDINGS or INVESTMENTS). Owners of 3+ group the exact owner name, counted for the 59 counties with 10,000+ complete records. “Share complete” is the county’s complete records against every row we store for it.
There’s no single-family column: Wisconsin's property class 1 is every residential parcel (houses, duplexes and condos alike), so its roll can't single out single-family homes. Wisconsin’s data here carries no homestead flag, so no column says whether the owner lives in the property.
