About this data
BEA Regional Price Parities are the federal government's official cost-of-living index, used by the Bureau of Labor Statistics, Bureau of Economic Analysis, and IRS for benefits adjustments. Index value 100 is the US national average, so a state RPP of 110 means goods and services cost 10% more than the US average, and an RPP of 90 means 10% less. Some demographic aggregators use composite indices like MERIC instead of the federal BEA RPP — the two disagree on roughly half the states because they weight rent, groceries, healthcare, and transportation differently. We use the federal index because it is methodologically transparent and standard across federal benefits programs.
