Consumer Inflation – Official vs Shadowstats (Apr. 2022) | Chart of the Week
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.
This chart is based on the methodology which was employed prior to 1980.
