ZIP code 21620

ZIP 21620 is a mid-size town in Kent County, Maryland, with 13,533 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #160 of 477 ranked by population — larger than 66% of them. The median age here is 42.9 years against 39.1 nationally, a slightly older profile than the country as a whole. Places under 65,000 residents only appear in the five-year release, never the one-year file, so these values pool sixty months of responses and lag the current year by design.

Households in ZIP 21620 earn a median of $76,094 a year, 3.1% below 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 10.8% of residents here, below the 12.4% national rate.

The typical owner-occupied home in ZIP 21620 is valued at $318,700, 5% above the national figure, while median gross rent runs $1,149 a month, 18.3% below the national figure, or roughly $13,788 across a full year. A household on the local median income would put about 18.1% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is cheap relative to what people here earn. The home-price-to-income ratio works out to 4.2×, against roughly 3.9× nationally, so buying is harder here than in the average US market. 71% of occupied homes are owner-occupied versus 65% nationally, so the market leans toward owners. The rent line includes utilities paid by the tenant, a definition worth remembering when comparing it against a landlord's quoted rate.

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 21620 is tabulated inside Kent County, Maryland, one of 9 ZIP areas the Census publishes for that county and 477 across Maryland. This is a mid-sized ZIP that covers a large share of its county's addresses.

Against its own county, 21620 reports a median household income of $76,094, close to the $74,375 county median, and 27% below the $104,338 typical MD ZIP. Owner-occupied homes are valued at a median of $318,700, 7% above the county figure and 21% below the statewide ZIP median. Rent is reported gross — the contract amount plus tenant-paid utilities — at $1,149 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 21620.

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 21620 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.
