Franklin Center, NJ population, income and ZIP codes

Franklin Center CDP is a mid-size town in New Jersey, with 5,770 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #268 of 700 ranked by population — larger than 61% of them. The median age here is 56.4 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 Center CDP earn a median of $138,643 a year, 76.5% above the national figure of $78,538 and 30% above the $106,926 median for the 543 New Jersey cities we cover. Household income here is measured before tax and pooled across everyone at the address, which is why it reads higher than typical individual earnings in the same area. Poverty reaches 5.6% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in Franklin Center CDP is valued at $565,200, 86.3% above the national figure and 37% above the $412,500 peer median, while median gross rent runs $2,588 a month, 84.1% above the national figure, or roughly $31,056 across a full year. A household on the local median income would put about 22.4% 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 4.1×, against roughly 3.9× nationally, so buying is harder here than in the average US market. 69.4% of occupied homes are owner-occupied versus 65% nationally, so the market leans toward owners. Gross rent folds in the utilities a tenant pays separately, so it is closer to the real monthly outlay than a headline rent figure.

A median age of 56.4 puts Franklin Center CDP well into retirement-weighted territory, which pulls median household income down even where household wealth is high, because retirement draws are counted differently from wages.

Every value on this page is published directly by the Census for this area — nothing is modelled or interpolated. 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.
