Westminster city, MD in context

How this area compares with national benchmarks.

Westminster city is a mid-size town in Maryland, with 20,257 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #69 of 536 ranked by population — larger than 87% of them. The median age here is 39.1 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 Westminster city earn a median of $79,431 a year, 1.1% above the national figure of $78,538 and 27% below the $109,026 median for the 332 Maryland cities we cover. 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 11.1% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Westminster city is valued at $318,100, 4.8% above the national figure and 20% below the $397,200 peer median, while median gross rent runs $1,410 a month, essentially level with the national figure, or roughly $16,920 across a full year. A household on the local median income would put about 21.3% 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 4×, against roughly 3.9× nationally, so buying is harder here than in the average US market. 55.5% of occupied homes are owner-occupied versus 65% nationally, so the market leans more heavily on renters. Gross rent folds in the utilities a tenant pays separately, so it is closer to the real monthly outlay than a headline rent figure.
