Florham Park, NJ population, income and ZIP codes

Florham Park borough is a mid-size town in New Jersey, with 13,134 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #103 of 700 ranked by population — larger than 85% of them. The median age here is 39.9 years against 39.1 nationally, a slightly older profile than the country as a whole. 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 Florham Park borough earn a median of $147,714 a year, 88.1% above the national figure of $78,538 and 38% 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 7.8% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Florham Park borough is valued at $722,700, 138.2% above the national figure and 75% above the $412,500 peer median, while median gross rent runs $3,009 a month, 114% above the national figure, or roughly $36,108 across a full year. A household on the local median income would put about 24.4% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is within the standard affordability guideline. The home-price-to-income ratio works out to 4.9×, against roughly 3.9× nationally, so buying is harder here than in the average US market. 69.6% of occupied homes are owner-occupied versus 65% nationally, so the market leans toward owners. The rent line includes utilities paid by the tenant, a definition worth remembering when comparing it against a landlord's quoted rate.

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.
