What it’s like

The place. Newark is a small town in Rock County where the population skews older than most places, and nearly everyone lives in a home they own. Incomes run well above the county's, and fewer residents live below the poverty line than you might expect. Winters are cold and snowy, with January the coldest month, while summers are warm, and precipitation through the year is moderate.

Work. Residents work mainly in manufacturing, professional and business services, schools, hospitals and social care, and shops. The commute is a fairly long one, and a modest share of people work from home. Across Rock County, the largest workplaces include Mercy Health System, Janesville School District and Beloit Memorial Hospital.

Things to do. The Pecatonica River is a short drive away, as is the Angel Museum, and Blackhawk Farms Raceway is close by for anyone who likes motor racing. For a longer outing, Rotary Botanical Gardens is a botanical garden a longer drive away, and Rock Cut State Park offers protected woodland and water, also a longer drive off.

FEMA’s National Risk Index (December 2025) rates the risk each natural hazard poses to the people, buildings and farms across Rock County, against the rest of the country; all of them together, relatively moderate. 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 Rock County and the Janesville-Beloit, WI metro.
