The Industry Turnover Index is a short-term indicator whose objective is to reflect the evolution of the activity of industrial Catalan companies based on their invoicing. As an index value, it measures the joint evolution of the quantities, quality and prices.
Idescat prepares the Turnover Index on Industry on a monthly basis. It also calculates the index of non-energy industrial products for Catalonia and Spain, which it disaggregates by large industrial sectors (defined by EC Regulation No. 656/2007 of the Commission of the European Communities, amending EC Regulation No. 586/2001, in reference to the definition of large industrial sectors).
The primary source of information is a continuous monthly survey carried out by the INE.
