RPP measures “… the differences in the price levels of goods and services across states and metropolitan areas for a given year. RPPs are expressed as a percentage of the overall national price level for each year.” Another way of explaining this is the cost-of-living in various regions/areas of the country. For example, using 100 as the base point, the RPP for the New York area is 122.3, while the RPP for Beckley, WV is 79.7, meaning it would cost someone in the New York area $122.30 to purchase $100 worth of goods or services, while in Beckley $79.70 would purchase $100 worth of goods/services. Use this interactive feature to arrive at the RPP for state-level data as well as metropolitan/non-metropolitan data.
