ZIP 20626 in context

How this area compares with national benchmarks.

ZIP 20626 is a very small community in St. Mary's County, Maryland, with 198 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #428 of 477 ranked by population — larger than 10% of them. The median age here is 69.1 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 ZIP 20626 earn a median of $53,143 a year, 32.3% below the national figure of $78,538. 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 21.2% 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 ZIP 20626 is valued at not published, while median gross rent runs not published a month. 93.2% 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. Gross rent folds in the utilities a tenant pays separately, so it is closer to the real monthly outlay than a headline rent figure.

A median age of 69.1 puts ZIP 20626 well into retirement-weighted territory, which pulls median household income down even where household wealth is high, because retirement draws are counted differently from wages. With 198 residents, a handful of survey responses moves every median on this page. Compare ZIP 20626 against its county rather than against national figures.

The Census withheld home value, gross rent for ZIP 20626 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.

Reading ZIP 20626 in context

How 20626 sits inside St. Mary's County and Maryland.

ZIP 20626 is tabulated inside St. Mary's County, Maryland, one of 26 ZIP areas the Census publishes for that county and 477 across Maryland. This is one of the smallest tabulated ZIP areas in the state, the kind of rural route where a single subdivision or farm cluster accounts for most addresses. County assignment on this page follows the largest share of the ZIP's land area, which matters where a delivery route crosses a county line: mail addressed to 20626 can be handled by a post office in a neighbouring county even though the tabulation area is filed here.

Against its own county, 20626 reports a median household income of $53,143, 55% below the $117,501 county median, and 49% below the $104,338 typical MD ZIP. Owner-occupied homes are valued at a median of not published. Rent is reported gross — the contract amount plus tenant-paid utilities — at not published a month, which is why it reads higher than the advertised rent on a listing for the same unit.

Maryland charges 6% statewide, and no local sales tax is layered on top, so the state rate is the full amount collected in 20626.

Everything above comes from the Census Bureau American Community Survey 2019-2023 ACS 5-year estimates for this ZIP Code Tabulation Area, with sales tax rates traced to the state revenue agency. Five-year estimates pool sixty months of responses, so they are stable enough to compare 20626 with its neighbours but always trail the current year, and any value the Census suppressed for sample size is shown as unpublished rather than filled in with a model.
