Milwaukee County — Wisconsin's Brew City and Economic Engine

Milwaukee County is the only Wisconsin county where 80% of total area is water — with 948 square miles of Lake Michigan within its boundaries, compared to just 241 square miles of land. The German immigrants who arrived in the 1850s built breweries along the bluffs, and by 1856 Milwaukee had over two dozen operating breweries. Pabst (founded 1844), Schlitz (1849), Miller, and Blatz — all four historic beer barons launched here. In 1903, four Milwaukee-born men founded Harley-Davidson Motor Company in a 10-by-15-foot wooden shed — the world's only Harley-Davidson Museum still stands at 400 W. Canal Street. Milwaukee County is one of the few fully incorporated counties in the United States — all 241 square miles fall within one of its 19 municipalities, leaving no unincorporated township land. Property tax rates at approximately 2.68% are Wisconsin's highest — reflecting dense urban infrastructure costs across 19 separate municipal service systems.
