Colonia, NJ population, income and ZIP codes

Colonia CDP is a mid-size town in New Jersey, with 18,294 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #67 of 700 ranked by population — larger than 90% of them. The median age here is 43.3 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 Colonia CDP earn a median of $134,301 a year, 71% above the national figure of $78,538 and 26% above 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 5.9% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in Colonia CDP is valued at $473,200, 56% above the national figure and 15% above the $412,500 peer median, while median gross rent runs $1,964 a month, 39.7% above the national figure, or roughly $23,568 across a full year. A household on the local median income would put about 17.5% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is cheap relative to what people here earn. The home-price-to-income ratio works out to 3.5×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 88.2% 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.

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.
