Antietam, MD population, income and ZIP codes

Antietam CDP is a very small community in Maryland, with 51 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #506 of 536 ranked by population — larger than 5% of them. The median age here is 59.6 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 Antietam CDP earn a median of not published a year. 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 0% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in Antietam CDP is valued at $360,000, 18.7% above the national figure and 9% below the $397,200 peer median, while median gross rent runs not published a month. 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. The rent line includes utilities paid by the tenant, a definition worth remembering when comparing it against a landlord's quoted rate.

A median age of 59.6 puts Antietam CDP 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. With 51 residents, a handful of survey responses moves every median on this page. Compare Antietam CDP against its county rather than against national figures.

The Census withheld household income, gross rent for Antietam CDP 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.
