This dataset was the basis for several studies. It includes individuals who are registered as unemployed at a Swiss regional employment agency in the year 2003. The data contains further information from different unemployment insurance databases (AVAM/ASAL) and social security records (AHV). Additionally, caseworkers employed in the period of 2003 to 2004 were surveyed through a written questionnaire in December 2004. The questionnaire asked about the caseworker’s aims and strategies and information about the regional employment agency.
