Johnston, SC population, income and ZIP codes

Johnston town is a small town in South Carolina, with 2,518 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #169 of 475 ranked by population — larger than 64% of them. The median age here is 45.7 years against 39.1 nationally, a markedly older profile that usually tracks retirees staying put and younger households leaving for work. 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 Johnston town earn a median of $34,957 a year, 55.5% below the national figure of $78,538 and 34% below the $53,071 median for the 263 South Carolina cities we cover. Median household income counts every pre-tax dollar arriving at an address — wages, self-employment, Social Security, pensions, interest and public assistance — for everyone living there, so multi-earner households pull the figure up even where individual pay is modest. Poverty reaches 27.1% of residents here, well above the 12.4% national rate, which is the single clearest signal in this dataset that median income here is carried by a narrow band of households.

The typical owner-occupied home in Johnston town is valued at $100,400, 66.9% below the national figure and 43% below the $177,100 peer median, while median gross rent runs $803 a month, 42.9% below the national figure, or roughly $9,636 across a full year. A household on the local median income would put about 27.6% 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 2.9×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 58.9% of occupied homes are owner-occupied versus 65% nationally, so the market leans more heavily on renters. Gross rent folds in the utilities a tenant pays separately, so it is closer to the real monthly outlay than a headline rent figure.

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.
