Annandale, NJ population, income and ZIP codes

Annandale CDP is a small town in New Jersey, with 1,751 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #483 of 700 ranked by population — larger than 31% of them. The median age here is 34.5 years against 39.1 nationally, a slightly younger profile than the country as a whole. 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 Annandale CDP earn a median of $149,886 a year, 90.8% above the national figure of $78,538 and 40% 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 2.5% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in Annandale CDP is valued at $482,700, 59.1% above the national figure and 17% above the $412,500 peer median, while median gross rent runs $2,662 a month, 89.3% above the national figure, or roughly $31,944 across a full year. A household on the local median income would put about 21.3% 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 3.2×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 71.8% of occupied homes are owner-occupied versus 65% nationally, so the market leans toward owners. 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.

All values below were released by the Census for this exact geography, with no gap-filling on our side. 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.
