The paper explores the challenges faced today, in a context of severe economic crisis, by immigrant associations (IMAs) and Non-Governmental Organizations (NGOs) in Greece. The data analysed here was collected between October 2009 and February 2010 and incorporates references to all recorded migration-related social actors operating in Greece. The paper takes into account such indicators as legal form, objectives, financial capacity and geographical range of activity, concluding with a typology of civil society actors dealing with migration issues. This study aims at informing the migration policymaking and migrant integration processes. By a spatial hot-spot clustering of IMAs and NGOs, we also illustrate the concentration patterns of civil society actors in Greece.
