The rent line carries the largest weight in the BEA methodology, so a metro with a higher rent index almost always ends up more expensive overall - Atlanta-Sandy Springs-Roswell carries the heavier rent load here, and that tends to dominate household budget experience on the ground.

In salary terms, a $100,000 income in Atlanta-Sandy Springs-Roswell has the same purchasing power as $93,608 in Columbia based on these indexes. The two metros serve populations of roughly 6,176,937 (Atlanta-Sandy Springs-Roswell) and 839,868 (Columbia), and median household incomes are $86,338 versus $66,146 respectively - so the right way to read this comparison is never the index alone, but the ratio of your expected local salary to the rent and services mix. For any serious relocation or remote-work decision, pair this BEA comparison with BLS occupation-specific wage data, HUD Fair Market Rent tables, and state tax treatment before committing.
