ZIP code 02639

ZIP 02639 is a small town in Barnstable County, Massachusetts, with 3,387 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #381 of 539 ranked by population — larger than 29% of them. The median age here is 52.4 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 ZIP 02639 earn a median of $64,051 a year, 18.4% below the national figure of $78,538. 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 13.3% of residents here, above the 12.4% national rate.

The typical owner-occupied home in ZIP 02639 is valued at $451,700, 48.9% above the national figure, while median gross rent runs $1,296 a month, 7.8% below the national figure, or roughly $15,552 across a full year. A household on the local median income would put about 24.3% 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 7.1×, 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. 71.9% of occupied homes are owner-occupied versus 65% nationally, so the market leans toward owners. 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 7.1× 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 52.4 puts ZIP 02639 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.

ZIP 02639 is tabulated inside Barnstable County, Massachusetts, one of 47 ZIP areas the Census publishes for that county and 539 across Massachusetts. Population sits in the small-town band, typically one main street plus the addresses that feed into it. County assignment on this page follows the largest share of the ZIP's land area, which matters where a delivery route crosses a county line: mail addressed to 02639 can be handled by a post office in a neighbouring county even though the tabulation area is filed here.

Against its own county, 02639 reports a median household income of $64,051, 35% below the $98,798 county median, and 40% below the $107,198 typical MA ZIP. Owner-occupied homes are valued at a median of $451,700, 29% below the county figure and 6% below the statewide ZIP median. Rent is reported gross — the contract amount plus tenant-paid utilities — at $1,296 a month, which is why it reads higher than the advertised rent on a listing for the same unit.

Massachusetts charges 6.25% statewide, and no local sales tax is layered on top, so the state rate is the full amount collected in 02639.

Everything above comes from the Census Bureau American Community Survey 2019-2023 ACS 5-year estimates for this ZIP Code Tabulation Area, with sales tax rates traced to the state revenue agency. Five-year estimates pool sixty months of responses, so they are stable enough to compare 02639 with its neighbours but always trail the current year, and any value the Census suppressed for sample size is shown as unpublished rather than filled in with a model.
