ZIP code 06351

ZIP 06351 is a mid-size town in New London County, Connecticut, with 15,697 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #88 of 288 ranked by population — larger than 69% of them. The median age here is 48.1 years against 39.1 nationally, a markedly older profile that usually tracks retirees staying put and younger households leaving for work. 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 ZIP 06351 earn a median of $84,107 a year, 7.1% above the national figure of $78,538. 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 7.4% of residents here, below the 12.4% national rate.

The typical owner-occupied home in ZIP 06351 is valued at $276,200, 9% below the national figure, while median gross rent runs $1,115 a month, 20.7% below the national figure, or roughly $13,380 across a full year. A household on the local median income would put about 15.9% 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. 80.4% 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. 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.

Every value on this page is published directly by the Census for this area — nothing is modelled or interpolated. 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.

ZIP 06351 is tabulated inside New London County, Connecticut, one of 33 ZIP areas the Census publishes for that county and 288 across Connecticut.

Against its own county, 06351 reports a median household income of $84,107, 20% below the $104,963 county median, and 21% below the $105,813 typical CT ZIP.

Rent is reported gross — the contract amount plus tenant-paid utilities — at $1,115 a month, which is why it reads higher than the advertised rent on a listing for the same unit.

Connecticut charges 6.35% statewide, and no local sales tax is layered on top, so the state rate is the full amount collected in 06351.

Everything above comes from the Census Bureau American Community Survey 2019-2023 ACS 5-year estimates for this ZIP Code Tabulation Area, with sales tax rates traced to the state revenue agency. Five-year estimates pool sixty months of responses, so they are stable enough to compare 06351 with its neighbours but always trail the current year, and any value the Census suppressed for sample size is shown as unpublished rather than filled in with a model.
