Ilchester CDP, MD in context
How this area compares with national benchmarks.
Ilchester CDP is a small city in Maryland, with 27,552 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #51 of 536 ranked by population — larger than 90% of them. The median age here is 36.3 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 Ilchester CDP earn a median of $150,783 a year, 92% above the national figure of $78,538 and 38% above 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 4% of residents here, less than half the 12.4% national rate.
The typical owner-occupied home in Ilchester CDP is valued at $498,500, 64.3% above the national figure and 26% above the $397,200 peer median, while median gross rent runs $1,963 a month, 39.6% above the national figure, or roughly $23,556 across a full year. A household on the local median income would put about 15.6% 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 3.3×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 77.9% of occupied homes are owner-occupied versus 65% nationally, so the market leans toward owners. The rent line includes utilities paid by the tenant, a definition worth remembering when comparing it against a landlord's quoted rate.
