The updating of the 1995-2018 historical series is part of the 2019 Statistical Review of national accounts carried out jointly by the bodies responsible for compiling these statistics: the INE, the Banco de España as regards the financial accounts of the institutional sectors and the IGAE as the body responsible for compiling the non-financial accounts of the public administration sector. This is a periodic review, typically every five years, which is standard practice in Member States. This statistical review does not entail any conceptual change.
