Harrington Park, NJ population, income and ZIP codes

Harrington Park borough is a small town in New Jersey, with 4,883 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #301 of 700 ranked by population — larger than 57% of them. The median age here is 46.7 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 Harrington Park borough earn a median of $180,515 a year, 129.8% above the national figure of $78,538 and 69% above the $106,926 median for the 543 New Jersey cities we cover. The median is the midpoint household, not an average, so a handful of very high earners cannot drag it upward the way they distort a mean. Poverty reaches 5.8% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in Harrington Park borough is valued at $709,200, 133.8% above the national figure and 72% above the $412,500 peer median, while median gross rent runs not published a month. The home-price-to-income ratio works out to 3.9×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 96.1% 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. The rent line includes utilities paid by the tenant, a definition worth remembering when comparing it against a landlord's quoted rate.

The Census withheld gross rent for Harrington Park borough 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.
