The Consumer Price Index (CPI) is a measure of the average change in prices paid by city consumers for a basket of consumer goods and services over time.
Inflation is an increase in the general price level. The official inflation rate is tracked by calculating changes in an indicator called the Consumer Price Index (CPI). CPI tracks changes in the cost of living over time. Like other economic measures, it's doing a pretty good job.
An upward change in the consumer price index (CPI) means that the average price change over time has increased. This ultimately leads to an adjustment of the cost of living and income (presumably so that income can be adjusted for rising costs of living). This process is called indexing.
