Spring Lake Heights, NJ population, income and ZIP codes

Spring Lake Heights borough is a small town in New Jersey, with 4,866 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #302 of 700 ranked by population — larger than 56% of them. The median age here is 41 years against 39.1 nationally, a slightly older 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 Spring Lake Heights borough earn a median of $102,829 a year, 30.9% above the national figure of $78,538 and 4% 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 4.2% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in Spring Lake Heights borough is valued at $648,500, 113.7% above the national figure and 57% above the $412,500 peer median, while median gross rent runs $1,817 a month, 29.2% above the national figure, or roughly $21,804 across a full year. A household on the local median income would put about 21.2% 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 6.3×, against roughly 3.9× nationally, so buying is out of reach on local earnings alone and the ownership market leans on outside income, equity or dual high earners. 60.1% 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.

Home values sit at 6.3× median household income, far past the 3.9× national mark, so ownership costs here are set by something other than local wages — second homes, retirees with equity, or commuters earning elsewhere.

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.
