The Federal Office for Migration and Refugees is presenting the first nationwide representative study comprising people from 49 Islamic countries and thus offering an extensive view of Muslim life throughout Germany. The research commissioned by the Deutsche Islam Konferenz (DIK; hereinafter referred to as the German Conference on Islam) gives unprecedented insight into the diversity of Muslim life in Germany as people from different contexts of origin were questioned about religion in everyday life and about aspects of structural and social integration. A total of 6,004 people aged 16 and above were surveyed by telephone; together with the information provided about other household members the analyses are based on data of almost 17,000 people.
