## Volume Index

An index that measures the aggregate production of a given set of goods and services over a period of time. For example, a volume index may measure changes in the amount of refined oil, corn and automobiles. A volume index may be an indicator of an economy's direction. That is, if production is falling, it may portend an economic downturn.
