ZIP 06455 in context
How this area compares with national benchmarks.
ZIP 06455 is a small town in Middlesex County, Connecticut, with 2,592 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #220 of 288 ranked by population — larger than 23% of them. The median age here is 51.1 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 06455 earn a median of $114,500 a year, 45.8% above the national figure of $78,538. 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 3% of residents here, less than half the 12.4% national rate.
The typical owner-occupied home in ZIP 06455 is valued at $392,500, 29.4% above the national figure, while median gross rent runs $1,110 a month, 21.1% below the national figure, or roughly $13,320 across a full year. A household on the local median income would put about 11.6% 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 3.4×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 93.9% 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. The rent line includes utilities paid by the tenant, a definition worth remembering when comparing it against a landlord's quoted rate.
A median age of 51.1 puts ZIP 06455 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.
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.
Reading ZIP 06455 in context
How 06455 sits inside Middlesex County and Connecticut.
ZIP 06455 is tabulated inside Middlesex County, Connecticut, one of 23 ZIP areas the Census publishes for that county and 288 across Connecticut. Population sits in the small-town band, typically one main street plus the addresses that feed into it. County assignment on this page follows the largest share of the ZIP's land area, which matters where a delivery route crosses a county line: mail addressed to 06455 can be handled by a post office in a neighbouring county even though the tabulation area is filed here.
Against its own county, 06455 reports a median household income of $114,500, 4% above the $109,901 county median, and 8% above the $105,813 typical CT ZIP. Owner-occupied homes are valued at a median of $392,500, 5% above the county figure and 13% above the statewide ZIP median. Rent is reported gross — the contract amount plus tenant-paid utilities — at $1,110 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 06455.
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 06455 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.

Affordability in this ZIP
Derived from the Census medians above — indicative, not an offer.
A rent burden above 30% is the federal threshold for cost-burdened households, and a price-to-income multiple above 4× is generally considered a stretched housing market. The mortgage figure is principal and interest only — taxes, insurance and HOA dues are extra.
