An index number in the context of statistics and economics is a measure of a change in some business activity over time.

It is constructed based on reliable information on relevant components, usually weighted according to importance.

An index number is usually defined relative to a specific base year, at which time the value of the index number would be assigned a round number, usually $100$ but sometimes $1000$.
