Does the Belgian minimum income system trap beneficiaries into dependency or is it a springboard to re-integration? What proportion of the active population has/has no access to minimum income protection? What are the characteristics of these groups? How can we measure the mobility between minimum income and other social protection states? This report presents and discusses original empirical indicators based on panel data for the period 1993-95, and draws policy conclusions for the improvement of the system. It is part of a comparative research (sponsored by the European Commission and the Belgian Minister of Social Integration) including Belgium, Denmark, the UK and Greece.
