A  cost-of-living index is a theoretical price index that measures relative cost of living over time or regions. It is an index that measures differences in the price of goods and services, and allows for substitutions with other items as prices vary.
The Cost of Living Index is a city-to-city comparison of key consumer costs across the country. A score of 100 represents the U.S. average. Thus, cities with an index score above 100 have a higher cost of living and cities with an index score below 100 have a lower cost of living in comparison to the U.S. average.
