Rosaryville, MD population, income and ZIP codes

Rosaryville CDP is a mid-size town in Maryland, with 12,206 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #117 of 536 ranked by population — larger than 78% of them. The median age here is 48.2 years against 39.1 nationally, a markedly older profile that usually tracks retirees staying put and younger households leaving for work. 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 Rosaryville CDP earn a median of $148,558 a year, 89.2% above the national figure of $78,538 and 36% above the $109,026 median for the 332 Maryland cities we cover. Median household income counts every pre-tax dollar arriving at an address — wages, self-employment, Social Security, pensions, interest and public assistance — for everyone living there, so multi-earner households pull the figure up even where individual pay is modest. Poverty reaches 3.8% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in Rosaryville CDP is valued at $457,600, 50.8% above the national figure and 15% above the $397,200 peer median, while median gross rent runs $2,542 a month, 80.8% above the national figure, or roughly $30,504 across a full year. A household on the local median income would put about 20.5% 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 3.1×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 94.1% 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. The rent line includes utilities paid by the tenant, a definition worth remembering when comparing it against a landlord's quoted rate.

Every value on this page is published directly by the Census for this area — nothing is modelled or interpolated. 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.
