What it’s like

The place. Sewaren is a small community in Middlesex County, home to a modest number of people. Household incomes run a little below the county's, and few residents live below the poverty line. A typical home here is worth a good deal, and a fair number of adults hold a four-year degree. Winters are cold, with January the coldest month and some snow each year, while summers turn hot by July and rain and melted snow fall steadily through the year.

Work. Residents work mostly in schools, hospitals and social care, with professional and business services, shops and manufacturing also employing many. Across Middlesex County, some of the largest workplaces are Rutgers University-New Brunswick, RWJ University Hospital New Brunswick and Novo Nordisk. A good number of people here work from home, and the county has seen jobs grow only slightly over the past year.

Things to do. Most of the better-known places nearby are a longer drive away. The Statue of Liberty is a famous tourist attraction, and the Hudson River runs along the same stretch of coast. Among the museums within a longer drive, the Metropolitan Museum of Art is one of the best known, and Central Park offers garden and open space.

FEMA’s National Risk Index (December 2025) rates the risk each natural hazard poses to the people, buildings and farms in Sewaren’s 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 Middlesex County and the New York-Newark-Jersey City, NY-NJ-PA metro.
