This report presents the findings of a survey of the current situation of research data management among social science researchers in Belgium.

The general conclusion of the report is that the needs of Belgian social science researchers are very real and that setting up a data archive for long-term preservation of social science datasets will not only solve several problems but also respond to the growing demand of reliable and reusable data sources. ...
