Eurostat has collected data on government interventions during the financial crisis for the years 2007 - 2011. The data are presented in two parts of the supplementary tables. Part 1 shows the actual impact of interventions on government deficit. Part 2 shows the actual and potential impact on government debt. Eurostat publishes individual tables for EU Member States (where there were reportable interventions) and a summary table with the aggregated data for the EU and the Euro area:
Eurostat also publishes a background note providing more information on the content of the tables and data findings:
