The Organisation of Islamic Cooperation has 57 members, 56 of which are also member states of the United Nations. Some, especially in West Africa, are – though with large Muslim populations – not necessarily Muslim majority countries. A few countries with significant Muslim populations, such as Russia and Thailand, sit as Observer States, while others, such as India and Ethiopia, are not members.
The collective population of OIC member states is over 1.6 billion as of 2008.
