What is cost of living? 

The cost of living is the amount of money it takes to cover basic expenses. State and region scores across the country give a snapshot of how expensive it is to live in a place based on earned wages. It's not enough to just compare wages and consumer prices because people who live in areas with higher expenses often make more money than those who live in less expensive places.

Cost of living index scores compare a certain area to the national average. There isn’t one federal index, and not every index calculates the cost of living the same, according to Investopedia. The score is generally pulled from the cost of housing, utilities, groceries, transportation, health care and miscellaneous goods and services.
