East Dennis, MA population, income and ZIP codes

East Dennis CDP is a small town in Massachusetts, with 3,685 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #142 of 248 ranked by population — larger than 42% of them. The median age here is 62.6 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 East Dennis CDP earn a median of $100,504 a year, 28% above the national figure of $78,538 and within a couple of points of the $99,537 median for the 222 Massachusetts cities we cover. Household income here is measured before tax and pooled across everyone at the address, which is why it reads higher than typical individual earnings in the same area. Poverty reaches 4.2% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in East Dennis CDP is valued at $658,500, 117% above the national figure and 32% above the $497,400 peer median, while median gross rent runs $721 a month, 48.7% below the national figure, or roughly $8,652 across a full year. A household on the local median income would put about 8.6% 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 6.6×, against roughly 3.9× nationally, so buying is out of reach on local earnings alone and the ownership market leans on outside income, equity or dual high earners. 84.2% 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.

Home values sit at 6.6× median household income, far past the 3.9× national mark, so ownership costs here are set by something other than local wages — second homes, retirees with equity, or commuters earning elsewhere. A median age of 62.6 puts East Dennis CDP 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.

All values below were released by the Census for this exact geography, with no gap-filling on our side. 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.
