"In general, the most expensive areas to live were Hawaii, Alaska, the Northeast, and the West Coast," the Missouri Department of Economic Development said in the report. "The least expensive areas were the Midwest and southern states."
Indiana had a cost of living index of 90 on a scale of 56.4 to 186.3, trailing only Missouri and Kansas in the Midwest. For contrast, California had a cost-of-living index of 137.2 and Hawaii, the most expensive state in the U.S., had an index of 188.9.
It was barely cheaper than neighboring Michigan, which ranked 10th cheapest nationwide, with an index of 90.2, but was appreciably cheaper than bordering Illinois, which ranked 22nd lowest nationally with an index of 95.7.
Indiana's low cost of living is in line with its lower incomes.
