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 http://www.clevelandfed.org/research/inflation/cfincludes/cpi.txt
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.
