What is the American inflation based on CPI?
When we talk about the rate of inflation in United States, this often refers to the rate of inflation based on the consumer price index, or CPI for short. The American CPI shows the change in prices of a standard package of goods and services which American households purchase for consumption.
In order to measure American inflation, an assessment is made of how much the American CPI has risen in percentage terms over a give period compared to the CPI in United States in a preceding period. If prices have fallen this is called deflation (negative inflation).
