The Bureau of Economic Analysis recently released its annual estimates of the relative cost of living in America's metropolitan and rural areas.

Specifically, the BEA published its regional price parities for 2017. These compare the price levels for various goods and services in different areas to the average national price.

For example, the Jackson, Tennessee, metropolitan area had a regional price parity of 82.2. That meant prices there were 82.2% as high as the national average, or in other words, 17.8% lower than average.
