Regional price parities (RPPs) are a Bureau of Economic Analysis measure of local price levels, expressed as a percentage of the national average, that let you compare buying power across states and metro areas for a given year.
What it means
The BEA publishes RPPs so you can compare how far the same dollar goes in different places — an RPP above 100 means prices run above the national average, below 100 means below. They add cost-of-living context next to local pay figures and are not a salary outcome claim. They describe area price levels only; they are not a personal take-home-pay or affordability estimate.
