ZIP code 21628

ZIP 21628 is a very small community in Queen Anne's County, Maryland, with 299 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #415 of 477 ranked by population — larger than 13% of them. The median age here is 47.9 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 21628 earn a median of $96,875 a year, 23.3% above the national figure of $78,538. This figure covers the household, not the worker: two people on ordinary wages at one address outrank a single professional in the same table. Poverty reaches 18.1% of residents here, above the 12.4% national rate.

The typical owner-occupied home in ZIP 21628 is valued at $168,300, 44.5% below the national figure, while median gross rent runs not published a month. The home-price-to-income ratio works out to 1.7×, against roughly 3.9× nationally, so purchase prices are unusually low against local pay, the pattern in places where supply is plentiful and wage growth has been flat. 100% 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.

Median income runs above the national figure while poverty also runs above it — a split distribution, not a uniformly comfortable place. Averages hide that; the two numbers together do not. With 299 residents, a handful of survey responses moves every median on this page. Compare ZIP 21628 against its county rather than against national figures.

The Census withheld gross rent for ZIP 21628 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.

ZIP 21628 is tabulated inside Queen Anne's County, Maryland, one of 12 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 21628 can be handled by a post office in a neighbouring county even though the tabulation area is filed here.

Against its own county, 21628 reports a median household income of $96,875, 3% below the $100,359 county median, and 7% below the $104,338 typical MD ZIP. Owner-occupied homes are valued at a median of $168,300, 58% below the county figure and 58% below the statewide ZIP median. 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 21628.

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 21628 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.
