La Plata, MD population, income and ZIP codes

La Plata town is a mid-size town in Maryland, with 10,470 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #134 of 536 ranked by population — larger than 75% of them. The median age here is 41.5 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 La Plata town earn a median of $121,707 a year, 55% above the national figure of $78,538 and 12% above the $109,026 median for the 332 Maryland 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 3.5% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in La Plata town is valued at $405,200, 33.6% above the national figure and within a couple of points of the $397,200 peer median, while median gross rent runs $1,483 a month, 5.5% above the national figure, or roughly $17,796 across a full year. A household on the local median income would put about 14.6% 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 3.3×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 77.5% of occupied homes are owner-occupied versus 65% nationally, so the market leans toward owners. Gross rent folds in the utilities a tenant pays separately, so it is closer to the real monthly outlay than a headline rent figure.

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.
