Northlake, SC population, income and ZIP codes

Northlake CDP is a small town in South Carolina, with 3,848 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #123 of 475 ranked by population — larger than 74% of them. The median age here is 47.4 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 Northlake CDP earn a median of $79,531 a year, 1.3% above the national figure of $78,538 and 50% above 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 10.1% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Northlake CDP is valued at $241,700, 20.3% below the national figure and 36% above the $177,100 peer median, while median gross rent runs $1,026 a month, 27% below the national figure, or roughly $12,312 across a full year. A household on the local median income would put about 15.5% 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×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 82.8% 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.

No figure on this page is estimated by us; each one comes straight from the published ACS tables for this area. 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.
