East Harwich, MA population, income and ZIP codes

East Harwich CDP is a mid-size town in Massachusetts, with 5,670 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #112 of 248 ranked by population — larger than 55% of them. The median age here is 60.1 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 East Harwich CDP earn a median of $108,157 a year, 37.7% above the national figure of $78,538 and 9% above the $99,537 median for the 222 Massachusetts cities we cover. 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 0.8% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in East Harwich CDP is valued at $585,400, 92.9% above the national figure and 18% above the $497,400 peer median, while median gross rent runs $2,213 a month, 57.4% above the national figure, or roughly $26,556 across a full year. A household on the local median income would put about 24.6% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is within the standard affordability guideline. The home-price-to-income ratio works out to 5.4×, against roughly 3.9× nationally, so buying is harder here than in the average US market. 89.3% 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 60.1 puts East Harwich 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.

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.
