Olney CDP, MD in context
How this area compares with national benchmarks.
Olney CDP is a small city in Maryland, with 36,000 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #29 of 536 ranked by population — larger than 94% of them. The median age here is 41.6 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 Olney CDP earn a median of $171,766 a year, 118.7% above the national figure of $78,538 and 58% 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 4.4% of residents here, less than half the 12.4% national rate.
The typical owner-occupied home in Olney CDP is valued at $632,400, 108.4% above the national figure and 59% above the $397,200 peer median, while median gross rent runs $2,409 a month, 71.3% above the national figure, or roughly $28,908 across a full year. A household on the local median income would put about 16.8% 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 3.7×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 88.6% 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.
