Princeton Junction, NJ population, income and ZIP codes

Princeton Junction CDP is a small town in New Jersey, with 1,842 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #472 of 700 ranked by population — larger than 32% of them. The median age here is 50.3 years against 39.1 nationally, a markedly older profile that usually tracks retirees staying put and younger households leaving for work. 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 Princeton Junction CDP earn a median of $219,375 a year, 179.3% above the national figure of $78,538 and 105% above 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 11.6% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Princeton Junction CDP is valued at $669,100, 120.5% above the national figure and 62% above the $412,500 peer median, while median gross rent runs not published a month. The home-price-to-income ratio works out to 3.1×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 79.7% of occupied homes are owner-occupied versus 65% nationally, so the market leans toward owners. Gross rent folds in the utilities a tenant pays separately, so it is closer to the real monthly outlay than a headline rent figure.

A median age of 50.3 puts Princeton Junction CDP well into retirement-weighted territory, which pulls median household income down even where household wealth is high, because retirement draws are counted differently from wages.

The Census withheld gross rent for Princeton Junction CDP because the sample was too thin to publish at this geography. Those values were suppressed at the source, not lost in our dataset, and we do not model a replacement. Everything else on this page comes straight from the ACS 2019-2023 ACS 5-year tables.
