Middle River CDP, MD in context
How this area compares with national benchmarks.
Middle River CDP is a small city in Maryland, with 31,616 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #39 of 536 ranked by population — larger than 92% of them. The median age here is 36.6 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 Middle River CDP earn a median of $74,198 a year, 5.5% below the national figure of $78,538 and 32% 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 16.2% of residents here, above the 12.4% national rate.
The typical owner-occupied home in Middle River CDP is valued at $251,200, 17.2% below the national figure and 37% below the $397,200 peer median, while median gross rent runs $1,639 a month, 16.6% above the national figure, or roughly $19,668 across a full year. A household on the local median income would put about 26.5% 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 3.4×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 65.2% of occupied homes are owner-occupied versus 65% nationally, so the market leans toward owners. Gross rent folds in the utilities a tenant pays separately, so it is closer to the real monthly outlay than a headline rent figure.
All values below were released by the Census for this exact geography, with no gap-filling on our side. 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.
