Finding the right city for a family isn't just about cheap rent — it's about income, healthcare, schools, and room to grow. We scored 3 cities in South Carolina on the metrics families care about, and Columbia comes out on top with a cost index of 94, median income of $55,653, and a healthcare index of 96.
Our family scoring model prioritizes four dimensions: household income above $60K (supporting a family-sized budget), cost index under 100 (keeping daily expenses manageable), healthcare index under 110 (critical for pediatric care and family premiums), and population above 200K (ensuring access to quality schools and youth programs). Columbia leads because it scores across all four. North Charleston and Charleston follow with different strengths in income and population.
The #1 spot goes to Columbia, and the breakdown explains why. Renters here pay $1,459/month — saving renters $5,232 per year compared to the national average. Meanwhile, Housing is the standout at index 84, making it one of the cheapest in the country for that category. The weak spot? Healthcare at 96. The 31% rent-to-income ratio is a pressure point — for median earners, housing takes more than recommended.
If you only look at rent, it's perfect. And for the typical household, zoom out and it's complicated. In Columbia, the healthcare index sits at 96 — not a dealbreaker, but worth knowing about.

Homes list at $226,769 — $240,601 below the national median — a genuine ownership opportunity. On the cost side, Housing leads the way at 84, while Healthcare trails at 96.
