The higher the price parity number for a given state, the more residents will pay for items such as housing, food, and transportation. The BEA calculates this by looking at the price of goods and services in the Consumer Price Index, as well as rents reported to the Census Bureau’s American Community Survey. A price parity figure of 118.8, like Hawaii’s, means that goods and services there cost almost 19% more than the national average. Prices in Mississippi, meanwhile, with a price parity of 86.2, are about 14% less than the national average.
