CPI Year-to-Year Growth
The CPI-U (consumer price index) is the broadest measure of consumer price inflation for goods and services published by the Bureau of Labor Statistics (BLS).
While the headline number usually is the seasonally-adjusted month-to-month change, the formal CPI is reported on a not-seasonally-adjusted basis, with annual inflation measured in terms of year-to-year percent change in the price index.
In the charts to the right we show two SGS-Alternate CPI estimates: One based on the pre-1990 official methodology for computing the CPI-U, and the other based on the methodology which was employed prior to 1980.
Please note: Our Data Download is currently only providing the 1980-Based numbers, but 1990-Based numbers will be introduced shortly.
