What measures the rate of inflation by comparing changes in the prices of a representative basket of goods and services such as clothing food housing and utilities?

The Consumer Price Index (CPI) measures the rate of inflation by comparing changes in the prices of a representative basket of goods and services, including clothing, food, housing, and utilities. It tracks the cost of this basket over time, reflecting how much consumers need to spend to maintain their standard of living. Changes in the CPI are used to assess inflation trends and can influence economic policy and cost-of-living adjustments.
