What it’s like
The place. Erin is a small town in Washington County where residents are older than in most places, and nearly everyone lives in a home they own. Household incomes run higher than across the county, and very few people live below the poverty line. Homes here are valued well above what is typical for the country, and fewer adults hold a four-year degree than the incomes might suggest.
Work. Many residents work in schools, hospitals and social care, with manufacturing, banks and insurance, and professional and business services close behind. Commutes are long, and a good number of people work from home. Across Washington County, the largest workplaces include the West Bend School District, QuadGraphics and St. Josephs Community Hospital, and the county has lost a few jobs over the past year while unemployment stays low.
Things to do. The Ashippun River runs in or beside town, and Druid Lake, a reservoir, is a short drive away. Little Switzerland, a ski area, is also a short drive away, which suits the snowy winters, when January brings highs well below freezing. For a longer outing, the Milwaukee Art Museum is a longer drive away.

FEMA’s National Risk Index (December 2025) rates the risk each natural hazard poses to the people, buildings and farms across Washington County, against the rest of the country; all of them together, relatively low. It is meant for planning, not a substitute for a local risk assessment or a flood map: FEMA’s index.
From the U.S. Census Bureau’s 2020 census and its American Community Survey (2020–2024 five-year estimates), and the Bureau of Labor Statistics. A survey, so each figure has a margin of error, and figures it is not sure of are left out. More on Washington County and the Milwaukee-Waukesha, WI metro.
