South Amboy city, NJ in context

How this area compares with national benchmarks.

South Amboy city is a mid-size town in New Jersey, with 9,714 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #164 of 700 ranked by population — larger than 76% of them. The median age here is 42.3 years against 39.1 nationally, a slightly older profile than the country as a whole. Places under 65,000 residents only appear in the five-year release, never the one-year file, so these values pool sixty months of responses and lag the current year by design.

Households in South Amboy city earn a median of $110,125 a year, 40.2% above the national figure of $78,538 and 3% 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.

A household on the local median income would put about 17.9% 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 3.3×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 55.2% of occupied homes are owner-occupied versus 65% nationally, so the market leans more heavily on renters.
