St. Martin CDP, MS in context

How this area compares with national benchmarks.

St. Martin CDP is a mid-size town in Mississippi, with 7,797 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #49 of 427 ranked by population — larger than 88% of them. The median age here is 38.3 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 St. Martin CDP earn a median of $53,488 a year, 31.9% below the national figure of $78,538 and 21% above the $44,178 median for the 191 Mississippi cities we cover. Household income here is measured before tax and pooled across everyone at the address, which is why it reads higher than typical individual earnings in the same area. Poverty reaches 12.4% of residents here, below the 12.4% national rate.

The typical owner-occupied home in St. Martin CDP is valued at $171,300, 43.5% below the national figure and 41% above the $121,300 peer median, while median gross rent runs $1,040 a month, 26% below the national figure, or roughly $12,480 across a full year. A household on the local median income would put about 23.3% 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 3.2×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 55.7% of occupied homes are owner-occupied versus 65% nationally, so the market leans more heavily on renters. The rent line includes utilities paid by the tenant, a definition worth remembering when comparing it against a landlord's quoted rate.
