Port Royal, SC population, income and ZIP codes

Port Royal town is a mid-size town in South Carolina, with 15,047 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #43 of 475 ranked by population — larger than 91% of them. The median age here is 25.8 years against 39.1 nationally, a distinctly younger profile, typical of places with students, military posts or a fast-growing family population. 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 Port Royal town earn a median of $70,330 a year, 10.5% below the national figure of $78,538 and 33% above the $53,071 median for the 263 South Carolina 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 10.6% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Port Royal town is valued at $298,000, 1.8% below the national figure and 68% above the $177,100 peer median, while median gross rent runs $1,606 a month, 14.2% above the national figure, or roughly $19,272 across a full year. A household on the local median income would put about 27.4% 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 4.2×, against roughly 3.9× nationally, so buying is harder here than in the average US market. 38.9% of occupied homes are owner-occupied versus 65% nationally, a renter-majority market, so rent figures matter more here than the home-value line. Gross rent folds in the utilities a tenant pays separately, so it is closer to the real monthly outlay than a headline rent figure.

A median age of 25.8 means a large student or early-career population; income medians in places like this understate household resources, since many residents are supported from outside the address.

All values below were released by the Census for this exact geography, with no gap-filling on our side. Small-area estimates still carry wider margins of error than state or national figures, so check the linked ACS tables before relying on them for lending, appraisal or legal work.
