Greenwich (Cumberland Co.), NJ population, income and ZIP codes

Greenwich CDP (Cumberland County) is a very small community in New Jersey, with 161 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #671 of 700 ranked by population — larger than 4% of them. The median age here is 40.3 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 Greenwich CDP (Cumberland County) earn a median of $127,813 a year, 62.7% above the national figure of $78,538 and 20% 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 0% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in Greenwich CDP (Cumberland County) is valued at $246,900, 18.6% below the national figure and 40% below the $412,500 peer median, while median gross rent runs $950 a month, 32.4% below the national figure, or roughly $11,400 across a full year. A household on the local median income would put about 8.9% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is cheap relative to what people here earn. The home-price-to-income ratio works out to 1.9×, against roughly 3.9× nationally, so purchase prices are unusually low against local pay, the pattern in places where supply is plentiful and wage growth has been flat. 78.2% 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.
