Gambrills CDP, MD in context

How this area compares with national benchmarks.

Gambrills CDP is a small town in Maryland, with 2,862 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #246 of 536 ranked by population — larger than 54% of them. The median age here is 42.3 years against 39.1 nationally, a slightly older profile than the country as a whole. 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 Gambrills CDP earn a median of $151,667 a year, 93.1% above the national figure of $78,538 and 39% above 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 6.3% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Gambrills CDP is valued at $584,400, 92.6% above the national figure and 47% above the $397,200 peer median, while median gross rent runs $1,867 a month, 32.8% above the national figure, or roughly $22,404 across a full year. A household on the local median income would put about 14.8% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is cheap relative to what people here earn. The home-price-to-income ratio works out to 3.9×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 90.3% 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. Gross rent folds in the utilities a tenant pays separately, so it is closer to the real monthly outlay than a headline rent figure.
