What it’s like

The place. Mars is a small borough in Butler County, Pennsylvania, with a population that stays small at the last census. More households own their homes than rent, though renters are still a sizable group. Typical home values here run high, and rents are not low either, while the county's median household income sits comfortably in the upper range for the region. Winters are cold, with January highs near freezing and lows well below it, and a fair amount of snow falls each year. Summers are warm, and rain and melted snow add up to a moderate yearly total.

Work. Many residents work in schools, hospitals and social care, with manufacturing, retail, and professional and business services also employing a good share. Across Butler County, some of the largest workplaces are Butler Memorial Hospital, Cleveland-Cliffs Butler Works and Seneca Valley Schools. Most people travel to their jobs rather than working from home, and the county has seen a small gain in jobs over the past year, with unemployment lower than a year earlier.

Things to do. For a day out, the Andy Warhol Museum and the Carnegie Museum of Art are both museums reachable by a longer drive. The Allegheny River is another longer drive away for time by the water. Each of these lies outside the borough itself, so a trip needs some planning.

Natural hazards

  1. LightningRelatively high
  2. Inland floodingRelatively moderate
  3. Strong windRelatively moderate
  4. Winter weatherRelatively moderate

FEMA’s National Risk Index (December 2025) rates the risk each natural hazard poses to the people, buildings and farms in Mars’ census tracts, 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 Butler County and the Pittsburgh, PA metro.
