The Turnover Index on Industry (IVNI) is a short-term indicator used to measure the monthly evolution of the turnover of industrial companies. It is a value index, i.e. it measures the joint evolution of amounts, qualities and prices.
To obtain this indicator, the INE conducts an on-going monthly survey. For Catalonia, it researches some 2,300 companies operating in the industrial sector, which are used to obtain the general index and the large industrial sectors indexes. Idescat calculates the non-energy industrial products index for Catalonia and Spain.
With the publication of the data for January 2018 based on 2015, Idescat complies with Council Regulation (EC) 1165/98 on short-term statistics, which establishes a change of basis every five years. The implementation of this new basis improves the representativeness of the indicator and updates the weighting structure and the sample of informant units. The linked sets of the indexes based on 2015 have been published since January 2005.
