Do you want to compare the economic performance of the different governments since 1985?
The Statistical Annex of the book Portuguese Economy has 140 spreadsheets in Excel with statistical data for the Portuguese and European economies, covering the period 1910-2013. You can order a CD with the data from Principia Editora.
Here you can find an update of the spreadsheet Tableau de Board which contains the latest update (April 2014) of the main economic indicators of the Portuguese economy in the context of the European Union, aggregated by the different governments, since 1985, with projections up to 2015. These projections use the latest published data of the European Commission.
