ZIP code 21651

ZIP 21651 is a small town in Kent County, Maryland, with 2,448 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #292 of 477 ranked by population — larger than 38% of them. The median age here is 37.6 years against 39.1 nationally, a slightly younger 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 ZIP 21651 earn a median of $71,983 a year, 8.3% below the national figure of $78,538. The median is the midpoint household, not an average, so a handful of very high earners cannot drag it upward the way they distort a mean. Poverty reaches 8.7% of residents here, below the 12.4% national rate.

The typical owner-occupied home in ZIP 21651 is valued at $259,500, 14.5% below the national figure, while median gross rent runs $1,245 a month, 11.5% below the national figure, or roughly $14,940 across a full year. A household on the local median income would put about 20.8% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is within the standard affordability guideline. The home-price-to-income ratio works out to 3.6×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 81.1% 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.

No figure on this page is estimated by us; each one comes straight from the published ACS tables for this area. 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.

ZIP 21651 is tabulated inside Kent County, Maryland, one of 9 ZIP areas the Census publishes for that county and 477 across Maryland. 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 21651 can be handled by a post office in a neighbouring county even though the tabulation area is filed here.

Against its own county, 21651 reports a median household income of $71,983, 3% below the $74,375 county median, and 31% below the $104,338 typical MD ZIP. Owner-occupied homes are valued at a median of $259,500, 13% below the county figure and 35% below the statewide ZIP median. Rent is reported gross — the contract amount plus tenant-paid utilities — at $1,245 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 21651.

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 21651 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.
