National Harbor, MD population, income and ZIP codes

National Harbor CDP is a small town in Maryland, with 4,418 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #216 of 536 ranked by population — larger than 59% of them. The median age here is 49.8 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 National Harbor CDP earn a median of $133,616 a year, 70.1% above the national figure of $78,538 and 23% above 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 6.5% of residents here, below the 12.4% national rate.

The typical owner-occupied home in National Harbor CDP is valued at $462,000, 52.3% above the national figure and 16% above the $397,200 peer median, while median gross rent runs $2,293 a month, 63.1% above the national figure, or roughly $27,516 across a full year. A household on the local median income would put about 20.6% 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 3.5×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 54.4% of occupied homes are owner-occupied versus 65% nationally, so the market leans more heavily on renters. 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.

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.
