ZIP 20623 in context
How this area compares with national benchmarks.
ZIP 20623 is a small town in Prince George's County, Maryland, with 2,846 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #279 of 477 ranked by population — larger than 41% of them. The median age here is 51 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 20623 earn a median of $132,386 a year, 68.6% 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 1.8% of residents here, less than half the 12.4% national rate.
The typical owner-occupied home in ZIP 20623 is valued at $452,400, 49.1% above the national figure, while median gross rent runs not published a month. The home-price-to-income ratio works out to 3.4×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 98.6% 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.
A median age of 51 puts ZIP 20623 well into retirement-weighted territory, which pulls median household income down even where household wealth is high, because retirement draws are counted differently from wages.
The Census withheld gross rent for ZIP 20623 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.
Reading ZIP 20623 in context
How 20623 sits inside Prince George's County and Maryland.
ZIP 20623 is tabulated inside Prince George's County, Maryland, one of 36 ZIP areas the Census publishes for that county and 477 across Maryland. Population sits in the small-town band, typically one main street plus the addresses that feed into it. 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 20623 can be handled by a post office in a neighbouring county even though the tabulation area is filed here.
Against its own county, 20623 reports a median household income of $132,386, 48% above the $89,632 county median, and 27% above the $104,338 typical MD ZIP. Owner-occupied homes are valued at a median of $452,400, 10% above the county figure and 13% above 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 20623.
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 20623 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.

Affordability in this ZIP
Derived from the Census medians above — indicative, not an offer.
A rent burden above 30% is the federal threshold for cost-burdened households, and a price-to-income multiple above 4× is generally considered a stretched housing market. The mortgage figure is principal and interest only — taxes, insurance and HOA dues are extra.
