Consumer Price Index is defined as a measure of the weighted aggregate change in retail prices paid by consumers for a given basket of goods and services. Price changes are measured by re-pricing the same basket of goods and services at regular intervals, and comparing aggregate costs with the costs of the same basket in a selected base period Price data for constructing the indices are collected by Kenya National Bureau of Statistics through a survey of retail prices for consumption goods and services. The percentage change of the CPI over a one-year period is what is usually referred to as inflation.
