Industrial production refers to the output of industrial establishments and factories in a country or region. It is a measure of the physical output of manufacturing, mining, and utility sectors in an economy. Industrial production is typically measured as an index that reflects changes in the volume of production over a period of time. The index measures the output of physical goods produced and also takes into account the energy and raw materials used in the production process. Industrial production is an important indicator of economic activity and can have an impact on currency values and stock prices.
