Marlow Heights, MD population, income and ZIP codes

Marlow Heights CDP is a mid-size town in Maryland, with 6,144 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #183 of 536 ranked by population — larger than 65% of them. The median age here is 40.5 years against 39.1 nationally, a slightly older profile than the country as a whole. 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 Marlow Heights CDP earn a median of $58,268 a year, 25.8% below the national figure of $78,538 and 47% below the $109,026 median for the 332 Maryland cities we cover. Household income here is measured before tax and pooled across everyone at the address, which is why it reads higher than typical individual earnings in the same area. Poverty reaches 24.3% of residents here, well above the 12.4% national rate, which is the single clearest signal in this dataset that median income here is carried by a narrow band of households.

The typical owner-occupied home in Marlow Heights CDP is valued at $366,700, 20.9% above the national figure and 8% below the $397,200 peer median, while median gross rent runs $1,638 a month, 16.5% above the national figure, or roughly $19,656 across a full year. A household on the local median income would put about 33.7% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is a stretch on median earnings. The home-price-to-income ratio works out to 6.3×, 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. 45% of occupied homes are owner-occupied versus 65% nationally, so the market leans more heavily on renters. Gross rent folds in the utilities a tenant pays separately, so it is closer to the real monthly outlay than a headline rent figure.

Home values sit at 6.3× 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.

Every value on this page is published directly by the Census for this area — nothing is modelled or interpolated. 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.
