ZIP code 20686

ZIP 20686 is a very small community in St. Mary's County, Maryland, with 949 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #350 of 477 ranked by population — larger than 26% of them. The median age here is 20 years against 39.1 nationally, a distinctly younger profile, typical of places with students, military posts or a fast-growing family population. 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.

With 949 residents, a handful of survey responses moves every median on this page. Compare ZIP 20686 against its county rather than against national figures.

The Census withheld household income, home value, gross rent, poverty rate for ZIP 20686 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.

Fewer than 2,500 people are counted here, so the ZIP behaves like a village delivery route rather than a neighbourhood. 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 20686 can be handled by a post office in a neighbouring county even though the tabulation area is filed here.

Maryland charges 6% statewide, and no local sales tax is layered on top, so the state rate is the full amount collected in 20686.

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 20686 with its neighbours but always trail the current year, and any value the Census suppressed for sample size is shown as unpublished rather than filled in with a model.
