What it’s like
The place. Interlaken is a very small borough in Monmouth County, with a quiet, settled feel. Nearly all of its homes are lived in by their owners, and household incomes run well above the county's, with very few residents living below the poverty line. Most adults have a four-year degree, and winters are cold while summers are warm, with a good deal of rain and melted snow through the year.
Work. Residents work mainly in professional and business services, in schools, hospitals and social care, in banks, insurance and property, and in restaurants, hotels and entertainment. The commute is on the long side, and a fair number of people work from home. Across Monmouth County, some of the largest workplaces are Jersey Shore University Medical Center, Monmouth Medical Center and Barnabas Health Medical Group.
Things to do. Deal Lake and Palace Amusements, an amusement park, are in or beside town. A short drive away is the Shark River, a river good for a walk along the water. For a longer outing, Coney Island is a beach a longer drive away.

Natural hazards
- Strong windVery high
- Winter weatherRelatively moderate
FEMA’s National Risk Index (December 2025) rates the risk each natural hazard poses to the people, buildings and farms in Interlaken’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 Monmouth County and the New York-Newark-Jersey City, NY-NJ-PA metro.
