Annual Inflation Rate

The average inflation rate per year for the US from 1960 to 2021 has been 3.64% despite being much higher and much lower in certain years.
The 1970's saw the highest rates of inflation as inflation reached levels as high of 13% until Paul Volker raised the fed funds rate to 20%.
This worked to bring down inflation where it reached its lowest levels since the early 1960's.
