The increasing demand for integration courses in Germany (especially due to the crisis-induced migration of refugees) has raised the question in research and practice of how this change affects the supply and participation of continuing education providers. To address this issue, the present study explores the impact of increasing integration course counts and participation on regular course counts and participation in German state-funded public adult education centers (Volkshochschulen; VHS), which are the main providers of integration courses. For this, we apply longitudinal fixed effects analyses to the VHS statistics. Controlling for VHS-specific trends, we find that on average, an increase in integration course counts slightly decreases regular course counts. Regarding participation, we observe the opposite: Increasing participation in integration courses leads to a small increase in participation in regular courses.
