What it’s like
The place. Andover is a very small borough in Sussex County, with far fewer residents than most towns, and it feels like a country town rather than a suburb. Homes here are valued well above what is typical across much of the country, and a smaller share of residents live below the poverty line than in many places. Winters are cold, with January the coldest month and highs staying close to freezing, while July brings warm days, and the year's rain and melted snow add up to a good deal of precipitation.
Work. Many residents work in schools, hospitals and social care, with others in professional and business services, shops and manufacturing. Across Sussex County, some of the largest workplaces are Thorlabs, which makes instrument lenses, Newton Medical Center and the Sparta Township Public School District. Commutes are long, and a fair number of people skip the trip altogether by working from home. Unemployment across the county has eased compared with a year earlier, and the county has added a few more jobs than the year before.
Things to do. Kittatinny Valley State Park is a protected area in or beside town, handy for a walk without much travel. A short drive away are the Wallkill River and Lake Hopatcong, a large reservoir. For a longer outing, Fulmer Falls is a waterfall that takes more of a drive to reach.

Staff on average in 2025, as each workplace reported it to OSHA with its injury records: 66 workplaces with 20 or more staff, 6,972 people in all across the county; Andover has none of its own.

Not listed: many offices and banks, which need not report to OSHA; military bases, whose staff OPM withholds; and, in about half the states, city and county governments.

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