What it’s like

The place. Union is a small city in Montgomery County where most homes are lived in by their owners, more so than in many places. Residents are somewhat younger than in much of the country, and household incomes run above the county's. Winters are cold, with January the coldest month and a fair amount of snow, while July brings warm summer days, and rain and melted snow fall steadily across the year.

Work. Residents work mostly in schools, hospitals and social care, with many others in professional and business services, manufacturing and shops. Some of the largest workplaces in Union are warehousing and distribution operations, including Amazon, DHL Supply Chain and The Procter & Gamble Company. A typical commute is a moderate one, and a small share of people work from home.

Things to do. Sycamore State Park is a protected area a short drive away, a place for time outdoors. Farther afield, the National Museum of the United States Air Force is a museum a longer drive away, and the Dayton Art Institute is another museum in the same longer-drive range. The Stillwater River is also within a longer drive for anyone who wants time by the water.

FEMA’s National Risk Index (December 2025) rates the risk each natural hazard poses to the people, buildings and farms in Union’s census tracts, against the rest of the country; all of them together, very 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 Montgomery County and the Dayton-Kettering, OH metro.
