Sewell, NJ population, income and ZIP codes

Sewell CDP is a small town in New Jersey, with 3,065 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #382 of 700 ranked by population — larger than 45% of them. The median age here is 52.4 years against 39.1 nationally, a markedly older profile that usually tracks retirees staying put and younger households leaving for work. At this population the ACS sample is small, so the margin of error around every dollar figure below is wide — treat the numbers as a band, not a point, and expect them to move between annual releases without the place itself changing.

Households in Sewell CDP earn a median of $135,141 a year, 72.1% above the national figure of $78,538 and 26% 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 6.8% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Sewell CDP is valued at $303,900, essentially level with the national figure and 26% below the $412,500 peer median, while median gross rent runs not published a month. The home-price-to-income ratio works out to 2.2×, against roughly 3.9× nationally, so purchase prices are unusually low against local pay, the pattern in places where supply is plentiful and wage growth has been flat. 99.1% 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.

A median age of 52.4 puts Sewell 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.

The Census withheld gross rent for Sewell CDP because the sample was too thin to publish at this geography. Those values were suppressed at the source, not lost in our dataset, and we do not model a replacement. Everything else on this page comes straight from the ACS 2019-2023 ACS 5-year tables.
