Marblehead, MA population, income and ZIP codes

Marblehead CDP is a mid-size town in Massachusetts, with 20,334 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #69 of 248 ranked by population — larger than 72% of them. The median age here is 49.1 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 Marblehead CDP earn a median of $165,859 a year, 111.2% above the national figure of $78,538 and 67% 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 3.8% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in Marblehead CDP is valued at $906,200, 198.7% above the national figure and 82% above the $497,400 peer median, while median gross rent runs $1,769 a month, 25.8% above the national figure, or roughly $21,228 across a full year. A household on the local median income would put about 12.8% 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 5.5×, against roughly 3.9× nationally, so buying is harder here than in the average US market. 82.8% 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.
