Consumer Price Index, U.S. City Average
The Consumer Price Index (CPI), calculated monthly by the U.S. Bureau of Labor Statistics, measures the average change over time in prices paid by consumers for a representative basket of goods and services, such as food, housing, transportation, and healthcare. As the most widely used indicator of inflation, the CPI tracks shifts in the cost of living, guiding policymakers, businesses, and consumers in adjusting wages, benefits, and economic decisions; when the CPI rises, it signals higher living costs and reduced purchasing power.
