Riverdale, NJ population, income and ZIP codes

Riverdale borough is a small town in New Jersey, with 4,084 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #336 of 700 ranked by population — larger than 52% of them. The median age here is 50.2 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 Riverdale borough earn a median of $96,667 a year, 23.1% above the national figure of $78,538 and 10% below the $106,926 median for the 543 New Jersey cities we cover. This figure covers the household, not the worker: two people on ordinary wages at one address outrank a single professional in the same table. Poverty reaches 10.1% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Riverdale borough is valued at $384,500, 26.7% above the national figure and 7% below the $412,500 peer median, while median gross rent runs $2,351 a month, 67.2% above the national figure, or roughly $28,212 across a full year. A household on the local median income would put about 29.2% 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×, against roughly 3.9× nationally, so buying is harder here than in the average US market. 71.4% 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.

A median age of 50.2 puts Riverdale borough 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.

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.
