This claim is true if the U.S. Federal Reserve reports a monthly annualized CPI, Core CPI, Median CPI or 16% mean CPI that exceeds 20%.
These statistics are currently available here:
CPI Core http://www.clevelandfed.org/research/inflation/cfincludes/core.txt
Median CPI http://www.clevelandfed.org/research/Inflation/cfincludes/mcpi_revised.txt
16% trimmed mean CPI http://www.clevelandfed.org/research/Inflation/cfincludes/trim_revised.txt
I intend to judge this based on the statistics published by the Federal Reserve Bank of Cleveland. In case ALL of the statistics listed become unavailable, I will use other statistics published by the Federal Reserve Bank of Cleveland.
In case no CPI statistics are published by the Federal Reserve Bank of Cleveland, I may substitute statistics from other sources, including other Federal Reserve Banks or the U.S. Department of Labor and Bureau of Labor Statistics.
If the Federal Reserve Bank of Cleveland changes its methodology for calculating CPI, I will used the new methodology. I will not look at retroactive changes in CPI calculations.
The annualized rate must exceed 20%. Hitting exactly 20% in the published data is not adequate.
Note: I will judge this on the due date. Any data unpublished before the due date, even if pertaining to periods before 2019 will not be considered. I will judge this yes before the due date if the claim is satisfied, even if later the figures are amended.
