Note: To obtain the results by Autonomous Communities, the Local Unit whose main activity is Services is considered a statistical unit. These local units may be part of Enterprises whose activity is included in other sectors and, in this case, their data at the Enterprise level is not included in the Services sector. Another difference between this regional data (by premises) and the national data (by enterprises) is that only in the latter is it necessary to apply internal flow consolidations to each enterprise. This explains why the total turnover is somewhat higher in regional data than in national data.
