Chained Consumer Price Index For All Urban Consumers (C-CPI-U)

Chained Consumer Price Index For All Urban Consumers (C-CPI-U)

The Bureau of Labor Statistics first began publishing the Chained Consumer Price Index for All Urban Consumers in August 2002. Designated the C-CPI-U, the index supplements the existing indexes already produced by the BLS: the CPI for All Urban Consumers (CPI-U) and the CPI for Urban Wage Earners and Clerical Workers (CPI-W).
