What it’s like
The place. Mount Arlington is a small borough in Morris County, built around the shores of Lake Hopatcong. The people who live here are older than in many towns, and most homes are lived in by their owners. Household incomes are below the county's, and renting costs a fair amount for those who do. Winters are cold and the summers warm, with a good deal of rain and melted snow across the year.
Work. Many residents work in schools, hospitals and social care, with others in professional and business services, shops and manufacturing. Across Morris County, some of the largest workplaces are Morristown Medical Center, Novartis Pharmaceutical US Headquarters and UPS. Commutes are on the long side, though a good number of people work from home, and more adults hold a four-year degree than in many towns.
Things to do. Lake Hopatcong, a large reservoir, sits in or beside town, as does Hopatcong State Park, a protected area for walking and time by the water. Bertrand Island Amusement Park is also in or beside town, and the Wallkill River is a short drive away. For a bigger outing, Fulmer Falls, a waterfall, is a longer drive away.

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