The Industrial Production Index (IPI) is a short-term indicator that measures the monthly evolution of the productive activity of the industrial branches, excluding construction, contained in the National Classification of Economic Activities 2009 (CNAE-2009). It therefore investigates the activities included in sections B, C, D and division 36: Water collection, treatment and supply, from section E of the CNAE-2009.
The IPI measures the joint evolution of quantity and quality, removing the influence of prices. In order to obtain this information a continuous monthly survey is carried out which investigates over 11,500 establishments every month.
