Lawrenceville, NJ population, income and ZIP codes

Lawrenceville CDP is a small town in New Jersey, with 3,947 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #342 of 700 ranked by population — larger than 51% of them. The median age here is 43.4 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 Lawrenceville CDP earn a median of $118,482 a year, 50.9% above the national figure of $78,538 and 11% 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 2.2% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in Lawrenceville CDP is valued at $413,600, 36.3% above the national figure and within a couple of points of the $412,500 peer median, while median gross rent runs $2,250 a month, 60% above the national figure, or roughly $27,000 across a full year. A household on the local median income would put about 22.8% 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 3.5×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 85.4% 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.

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.
