Rainbow Lakes, NJ population, income and ZIP codes

Rainbow Lakes CDP is a small town in New Jersey, with 1,376 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #519 of 700 ranked by population — larger than 25% of them. The median age here is 31.7 years against 39.1 nationally, a distinctly younger profile, typical of places with students, military posts or a fast-growing family population. 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 Rainbow Lakes CDP earn a median of $109,083 a year, 38.9% above the national figure of $78,538 and within a couple of points of the $106,926 median for the 543 New Jersey cities we cover. Household income here is measured before tax and pooled across everyone at the address, which is why it reads higher than typical individual earnings in the same area. Poverty reaches 3.7% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in Rainbow Lakes CDP is valued at $531,700, 75.2% above the national figure and 29% above the $412,500 peer median, while median gross rent runs $2,079 a month, 47.9% above the national figure, or roughly $24,948 across a full year. A household on the local median income would put about 22.9% 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 4.9×, against roughly 3.9× nationally, so buying is harder here than in the average US market. 65% of occupied homes are owner-occupied versus 65% nationally, so the market leans more heavily on renters. Gross rent folds in the utilities a tenant pays separately, so it is closer to the real monthly outlay than a headline rent figure.

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.
