Based on the data from the INE's activity index in the services sector (IASS), every quarter Idescat draws up a short-term report on the indicators in the services sector. This report includes the general turnover index (IASSVN) broken down into five sectors and the production index in the services sector (IPROSS). The latter is obtained from the aggregate value added index (IAVASS) once the influence of prices on the economic activity (deflator) is eliminated.
