Fort Belvoir, VA population, income and ZIP codes

Fort Belvoir CDP is a mid-size town in Virginia, with 8,107 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #153 of 688 ranked by population — larger than 77% of them. The median age here is 18.9 years against 39.1 nationally, a distinctly younger profile, typical of places with students, military posts or a fast-growing family population. 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 Fort Belvoir CDP earn a median of $101,237 a year, 28.9% above the national figure of $78,538 and 22% above the $82,986 median for the 383 Virginia 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 3.6% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in Fort Belvoir CDP is valued at $244,400, 19.4% below the national figure and 16% below the $291,300 peer median, while median gross rent runs $3,212 a month, 128.4% above the national figure, or roughly $38,544 across a full year. A household on the local median income would put about 38.1% 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 2.4×, against roughly 3.9× nationally, so purchase prices are unusually low against local pay, the pattern in places where supply is plentiful and wage growth has been flat. 1.8% of occupied homes are owner-occupied versus 65% nationally, a renter-majority market, so rent figures matter more here than the home-value line. 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.

Fort Belvoir CDP is the unusual combination of expensive to rent and cheap to buy: rent takes 38.1% of median income while homes cost only 2.4× it. Where that pattern shows up, the gap is normally down to down-payment and credit barriers rather than price. A median age of 18.9 means a large student or early-career population; income medians in places like this understate household resources, since many residents are supported from outside the address.

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.
