Lake Hopatcong, NJ population, income and ZIP codes

Lake Hopatcong CDP is a mid-size town in New Jersey, with 10,383 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #146 of 700 ranked by population — larger than 79% of them. The median age here is 46.5 years against 39.1 nationally, a markedly older profile that usually tracks retirees staying put and younger households leaving for work. Places under 65,000 residents only appear in the five-year release, never the one-year file, so these values pool sixty months of responses and lag the current year by design.

Households in Lake Hopatcong CDP earn a median of $111,614 a year, 42.1% above the national figure of $78,538 and 4% above the $106,926 median for the 543 New Jersey cities we cover. Median household income counts every pre-tax dollar arriving at an address — wages, self-employment, Social Security, pensions, interest and public assistance — for everyone living there, so multi-earner households pull the figure up even where individual pay is modest. Poverty reaches 3.6% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in Lake Hopatcong CDP is valued at $388,300, 28% above the national figure and 6% below the $412,500 peer median, while median gross rent runs $1,599 a month, 13.7% above the national figure, or roughly $19,188 across a full year. A household on the local median income would put about 17.2% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is cheap relative to what people here earn. The home-price-to-income ratio works out to 3.5×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 93.4% of occupied homes are owner-occupied versus 65% nationally, an owner-dominated market where rental listings are scarce and rent medians rest on a thin sample. Gross rent folds in the utilities a tenant pays separately, so it is closer to the real monthly outlay than a headline rent figure.

All values below were released by the Census for this exact geography, with no gap-filling on our side. Small-area estimates still carry wider margins of error than state or national figures, so check the linked ACS tables before relying on them for lending, appraisal or legal work.
