South Carolina levies a graduated state income tax (top rate 6.20%); a household at the local median AGI of $49,911 would pay roughly $1,857/year before deductions. New residents arriving here predominantly come from Orangeburg County, SC (IRS SOI Migration, 2022-2023). Healthcare access is the area's quieter strength; school options sit on the lighter side, so families may find themselves looking at districts a few ZIPs over. Notable: median household income $50,170, fair market rent of $1,010 for a two-bedroom, and a typical home value of $137,984, down 2.8% over the past year. Every figure on this page links to its underlying federal dataset with a retrieval date so you can audit the freshness yourself.
The two domains pull in different directions. Healthcare access reads strong, but the on-paper school count is on the lighter side — that’s less a quality signal and more a density one. Households here often look at districts a few ZIPs over for school choice while keeping their providers local.
One concrete reading worth keeping: Depression prevalence sits near the national rate at 21.8%. Each figure on this page links to the original federal dataset with its retrieval date — this synthesis is a reading, not a substitute for the underlying records.
