Quantity index

The quantity index is a ratio describing relative changes in the quantity of produced goods or services relative to the base period. It is obtained when the change in prices is removed from a value index by dividing the value index by a price index and by multiplying the quotient by one hundred. This is also known as deflation. The quantity index can also be produced direct from quantity data without deflation with a price index. Quantity indices are produced on trade and construction, while volume indices are produced on industry and services.
