Definition of Consumer Price Index (CPI)
The Consumer Price Index (CPI) is a metric designed to track the average price level that consumers pay for a representative 'shopping basket' of goods and services. This basket typically includes items such as food, beverages, utilities, rent, healthcare, education, and financial services. Consequently, an increase in the CPI signifies a rise in the economy's overall price level.
