ZIP code 20724

ZIP 20724 is a mid-size town in Anne Arundel County, Maryland, with 18,669 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #131 of 477 ranked by population — larger than 72% of them. The median age here is 35.6 years against 39.1 nationally, a slightly younger 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 20724 earn a median of $109,530 a year, 39.5% above 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 10.1% of residents here, below the 12.4% national rate.

The typical owner-occupied home in ZIP 20724 is valued at $392,500, 29.4% above the national figure, while median gross rent runs $2,199 a month, 56.4% above the national figure, or roughly $26,388 across a full year. A household on the local median income would put about 24.1% 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. 59.8% of occupied homes are owner-occupied versus 65% nationally, so the market leans more heavily on renters. 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.

Maryland charges 6% statewide, and no local sales tax is layered on top, so the state rate is the full amount collected in 20724.

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 20724 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.
