Martinsburg, WV population, income and ZIP codes

Martinsburg city is a mid-size town in West Virginia, with 18,805 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #6 of 439 ranked by population — larger than 98% of them. The median age here is 37.5 years against 39.1 nationally, a slightly younger 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 Martinsburg city earn a median of $54,590 a year, 30.5% below the national figure of $78,538 and 3% above the $52,974 median for the 148 West Virginia cities we cover. 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 23% 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 Martinsburg city is valued at $231,900, 23.6% below the national figure and 82% above the $127,200 peer median, while median gross rent runs $1,090 a month, 22.5% below the national figure, or roughly $13,080 across a full year. A household on the local median income would put about 24% 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 4.2×, against roughly 3.9× nationally, so buying is harder here than in the average US market. 50.2% of occupied homes are owner-occupied versus 65% nationally, so the market leans more heavily on renters. The rent line includes utilities paid by the tenant, a definition worth remembering when comparing it against a landlord's quoted rate.
