About Inflation and the CPI

Inflation is the rate at which the general level of prices for goods and services rises, resulting in a decrease in purchasing power. The Consumer Price Index (CPI) is a common measure used to track inflation.

Understanding the CPI

The Consumer Price Index (CPI) measures the average change over time in the prices paid by urban consumers for a market basket of consumer goods and services. The CPI is used as an economic indicator, a deflator of other economic series, and a means of adjusting pound values.
