Overview

The Consumer Price Index (CPI) is designed to measure the average price changes of a fixed basket of consumption goods and services commonly purchased by resident households over time. It measures price movements (i.e., changes in prices) but not absolute price levels at a point in time.

The CPI is used as:
•    A measure of consumer price inflation
•    Inputs in the formulation of government policies
•    As a means of deriving real values in the compilation of economic statistics
