Look, the food & groceries sub-index is derived from overall cost of living with regional BLS price adjustments. A score of 103 (the top-10 average here) means food & groceries costs are about -3% below the national median. Columbia leads at 92, followed by North Charleston (99) and Charleston (118). Note: a low food & groceries index doesn't guarantee a low overall cost — check the full cost breakdown table below. Can we talk about how broken the conversation around affordability is? A city gets labeled 'cheap' and suddenly everyone assumes there's a catch — bad schools, no jobs, nothing to do. Take it or leave it — the data is what it is. But look at the income numbers here. Look at the cost categories. This isn't a budget consolation prize. It's a genuine alternative to the coastal rat race, and the data makes that case more convincingly than any think piece.
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.
