New London, CT population, income and ZIP codes

New London city is a small city in Connecticut, with 27,199 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #23 of 215 ranked by population — larger than 89% of them. The median age here is 35.1 years against 39.1 nationally, a slightly younger 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 New London city earn a median of $60,123 a year, 23.4% below the national figure of $78,538 and 38% below the $96,484 median for the 159 Connecticut 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 21% of residents here, well above the 12.4% national rate, which is the single clearest signal in this dataset that median income here is carried by a narrow band of households.

The typical owner-occupied home in New London city is valued at $234,800, 22.6% below the national figure and 32% below the $344,200 peer median, while median gross rent runs $1,303 a month, 7.3% below the national figure, or roughly $15,636 across a full year. A household on the local median income would put about 26% 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 3.9×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 40.1% of occupied homes are owner-occupied versus 65% nationally, a renter-majority market, so rent figures matter more here than the home-value line. Rent is reported gross — contract rent plus tenant-paid utilities — which is why it runs above the advertised price on a listing for the same unit.

All values below were released by the Census for this exact geography, with no gap-filling on our side. 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.
