Target Group Monitoring is a regional approach to generate data to cover adequately the information needs of labour market actors. Approaches from different European regions are presented in this book, applied onto migrants as a target group of labour market politics. Furthermore, the central elements of these approaches are discussed with respect to their suitability for other target groups, such as older or young employees, low-skilled and skilled workers. Finally, methods and techniques are considered to provide a wide scope of information in combining target group and branch/industry approaches. This book was developed by several members of the European Network of Regional Labour Market Monitoring.
