ZIP code 06357

ZIP 06357 is a mid-size town in New London County, Connecticut, with 11,315 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #116 of 288 ranked by population — larger than 59% of them. The median age here is 55.9 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 06357 earn a median of $98,852 a year, 25.9% above the national figure of $78,538. The median is the midpoint household, not an average, so a handful of very high earners cannot drag it upward the way they distort a mean. Poverty reaches 3.9% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in ZIP 06357 is valued at $369,600, 21.8% above the national figure, while median gross rent runs $1,476 a month, 5% above the national figure, or roughly $17,712 across a full year. 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 3.7×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 77% of occupied homes are owner-occupied versus 65% nationally, so the market leans toward owners. 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.

A median age of 55.9 puts ZIP 06357 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.

No figure on this page is estimated by us; each one comes straight from the published ACS tables for this area. 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.

Connecticut charges 6.35% statewide, and no local sales tax is layered on top, so the state rate is the full amount collected in 06357.

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 06357 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.
