ZIP code 06438

ZIP 06438 is a small town in Middlesex County, Connecticut, with 3,012 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #214 of 288 ranked by population — larger than 25% of them. The median age here is 45.8 years against 39.1 nationally, a markedly older profile that usually tracks retirees staying put and younger households leaving for work. 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 ZIP 06438 earn a median of $127,905 a year, 62.9% 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 3.1% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in ZIP 06438 is valued at $376,500, 24.1% above the national figure, while median gross rent runs $1,579 a month, 12.3% above the national figure, or roughly $18,948 across a full year. A household on the local median income would put about 14.8% 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 2.9×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 82.4% 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.

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.

Owner-occupied homes are valued at a median of $376,500, close to the county figure and 8% above the statewide ZIP median.

Connecticut charges 6.35% statewide, and no local sales tax is layered on top, so the state rate is the full amount collected in 06438.

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 06438 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.
