@chris0699 This isn't the results of any study, it's really just clickbait.
SmartAsset simply took MITs cost of living calculator for each region and doubled it. The absurdly high numbers are just to drive traffic to their site. Sadly the clickbait works.

The only number that really matters, though, is whatever you decide it is for yourselves.
