Business Turnover Index

The Business Turnover Index (BTI) is a synthesis statistical operation which allows obtaining a short-term indicator that measures the short-term evolution of turnover, as a whole, for non-financial economic sectors: Extractive and manufacturing industries, Electrical energy and water, Trade and Non-financial services.

In order to obtain this indicator, the information from three surveys carried out by INE will be used. These surveys are the following: Industrial Turnover Indices (ITI), Services Sector Activity Indicators (SSAI) and Retail Trade Indices (RTI). For the rest of sectors not researched by INE, the information will be completed with data provided by the Tax Agency.
