Mount Rainier, MD population, income and ZIP codes

Mount Rainier city is a mid-size town in Maryland, with 8,235 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #160 of 536 ranked by population — larger than 70% of them. The median age here is 40 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 Mount Rainier city earn a median of $68,281 a year, 13.1% below the national figure of $78,538 and 37% below the $109,026 median for the 332 Maryland cities we cover. 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 6.6% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Mount Rainier city is valued at $522,100, 72.1% above the national figure and 31% above the $397,200 peer median, while median gross rent runs $1,434 a month, 2% above the national figure, or roughly $17,208 across a full year. A household on the local median income would put about 25.2% 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 7.6×, against roughly 3.9× nationally, so buying is out of reach on local earnings alone and the ownership market leans on outside income, equity or dual high earners. 24.3% of occupied homes are owner-occupied versus 65% nationally, a renter-majority market, so rent figures matter more here than the home-value line. 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.

Home values sit at 7.6× median household income, far past the 3.9× national mark, so ownership costs here are set by something other than local wages — second homes, retirees with equity, or commuters earning elsewhere.

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.
