Religion in Egypt controls many aspects of social life and is endorsed by law. The state religion of Egypt is Islam. Although estimates vary greatly in the absence of official statistics. Since the 2006 census religion has been excluded, and thus available statistics are estimates made by religious and non-governmental agencies. The country is majority Sunni Muslim (estimated to be 85-95% of the population), with the next largest religious group being Coptic Christians (with estimates ranging from 5- 15%). The exact numbers are subject to controversy, with Christians alleging that they have been systemically under-counted in existing censuses.
