Plymouth ZIP codes — Plymouth County, Massachusetts

Plymouth County is a major city in Massachusetts, with 531,889 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates. The median age here is 42.9 years against 39.1 nationally, a slightly older profile than the country as a whole. At this size the Census also publishes one-year estimates; the five-year values used here are steadier and let you compare against smaller neighbours on the same basis.

Households in Plymouth County earn a median of $109,698 a year, 39.7% above the national figure of $78,538. 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 7.1% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Plymouth County is valued at $513,000, 69.1% above the national figure, while median gross rent runs $1,655 a month, 17.7% above the national figure, or roughly $19,860 across a full year. A household on the local median income would put about 18.1% 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 4.7×, against roughly 3.9× nationally, so buying is harder here than in the average US market. 77.6% 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.

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.
