Upper Marlboro, MD population, income and ZIP codes

Upper Marlboro town is a very small community in Maryland, with 752 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #360 of 536 ranked by population — larger than 32% of them. The median age here is 34.9 years against 39.1 nationally, a slightly younger profile than the country as a whole. 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 Upper Marlboro town earn a median of $115,568 a year, 47.1% above the national figure of $78,538 and 6% above the $109,026 median for the 332 Maryland 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 1.5% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in Upper Marlboro town is valued at $299,700, 1.2% below the national figure and 25% below the $397,200 peer median, while median gross rent runs $1,786 a month, 27% above the national figure, or roughly $21,432 across a full year. A household on the local median income would put about 18.5% 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 2.6×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 88.1% 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.

With 752 residents, a handful of survey responses moves every median on this page. Compare Upper Marlboro town against its county rather than against national figures.

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.
