St. Leonard, MD population, income and ZIP codes

St. Leonard CDP is a very small community in Maryland, with 562 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #374 of 536 ranked by population — larger than 30% of them. The median age here is 44.8 years against 39.1 nationally, a slightly older profile than the country as a whole. 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 St. Leonard CDP earn a median of $188,056 a year, 139.4% above the national figure of $78,538 and 72% 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 0% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in St. Leonard CDP is valued at $489,500, 61.3% above the national figure and 23% above the $397,200 peer median, while median gross rent runs not published a month. The home-price-to-income ratio works out to 2.6×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 95.9% of occupied homes are owner-occupied versus 65% nationally, an owner-dominated market where rental listings are scarce and rent medians rest on a thin sample. 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.

With 562 residents, a handful of survey responses moves every median on this page. Compare St. Leonard CDP against its county rather than against national figures.

The Census withheld gross rent for St. Leonard CDP because the sample was too thin to publish at this geography. Those values were suppressed at the source, not lost in our dataset, and we do not model a replacement. Everything else on this page comes straight from the ACS 2019-2023 ACS 5-year tables.
