Index numbers:

These start with a value of 100 for a base year with subsequent values measured as a percentage change from the base; e.g., a value of 105 means the variable measured by the index has risen by 5% compared with the base year. A familiar index is the retail price index, which measures changes in retail prices and therefore serves as one measure of the rate of inflation.
