Portland, CT population, income and ZIP codes

Portland CDP is a mid-size town in Connecticut, with 5,970 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #61 of 215 ranked by population — larger than 71% of them. The median age here is 40.9 years against 39.1 nationally, a slightly older 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 Portland CDP earn a median of $91,522 a year, 16.5% above the national figure of $78,538 and 5% 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 7.2% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Portland CDP is valued at $267,600, 11.8% below the national figure and 22% below the $344,200 peer median, while median gross rent runs $1,112 a month, 20.9% below the national figure, or roughly $13,344 across a full year. A household on the local median income would put about 14.6% 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 2.9×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 75.1% of occupied homes are owner-occupied versus 65% nationally, so the market leans toward owners. The rent line includes utilities paid by the tenant, a definition worth remembering when comparing it against a landlord's quoted rate.

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.
