According to another Pew report, concerning religious identity among Muslims, it was determined that in Guinea-Bissau there is no prevailing sectarian identity. Under this same category were other Sub-Saharan countries like Tanzania, Uganda, Liberia, Nigeria and Cameroon. Other nations around the world claimed to be either predominantly Just Muslim, Mix of Sunni and Shia, or predominantly Sunni (pg. 30). This Pew research also stated that countries in this specific study that declared to not have any clear dominant sectarian identity were mostly concentrated in Sub-Saharan Africa. Another Pew report, ''The Future of World Religions'', predicts that from 2010 to 2050 Islam will increase its percent of the population in Guinea-Bissau.
