The U.S. Census Bureau uses the R-CPI-U-RS to adjust some of its income measures for changes in the cost of living.
Notes on verification
Confirmed directly by BLS and Census Bureau sources, including official guidance pages and a Federal Register notice. Note: as of 2025, Census now uses C-CPI-U for years 2000+ and R-CPI-U-RS only for pre-2000 data, but the claim as worded remains accurate.
