Franklin Lakes, NJ population, income and ZIP codes

Franklin Lakes borough is a mid-size town in New Jersey, with 11,011 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #130 of 700 ranked by population — larger than 81% of them. The median age here is 46.9 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 Franklin Lakes borough earn a median of $230,987 a year, 194.1% above the national figure of $78,538 and 116% 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 3.2% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in Franklin Lakes borough is valued at $1,217,500, 301.3% above the national figure and 195% above the $412,500 peer median, while median gross rent runs $3,334 a month, 137.1% above the national figure, or roughly $40,008 across a full year. A household on the local median income would put about 17.3% 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 5.3×, against roughly 3.9× nationally, so buying is harder here than in the average US market. 88.3% 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. Rent is reported gross — contract rent plus tenant-paid utilities — which is why it runs above the advertised price on a listing for the same unit.

No figure on this page is estimated by us; each one comes straight from the published ACS tables for this area. 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.
