Encyclopædia Britannica, (2003) ISBN 978-0-85229-956-2 p.306 According to the Encyclopædia Britannica, as of mid-2002, there were 376,453,000 Christians, 329,869,000 Muslims and 98,734,000 people who practiced traditional religions in Africa. Ian S. Markham, (A World Religions Reader. Cambridge, MA: Blackwell Publishers, 1996.) is cited by Morehouse University as giving the mid-1990s figure of 278,250,800 Muslims in Africa, but still as 40.8% of the total population. These numbers are estimates, and remain a matter of conjecture. See Amadu Jacky Kaba. The spread of Christianity and Islam in Africa: a survey and analysis of the numbers and percentages of Christians, Muslims and those who practice indigenous religions. The Western Journal of Black Studies, Vol 29, Number 2, June 2005. Discusses the estimations of various almanacs and encyclopedium, placing Britannica's estimate as the most agreed figure. Notes the figure presented at the World Christian Encyclopedia, summarized hereArchived 5 March 2016 di Wayback Machine., as being an outlier. On rates of growth, Islam and Pentecostal Christianity are highest, see: The List: The World’s Fastest-Growing ReligionsArchived 21 May 2007 di Wayback Machine., Foreign Policy, May 2007.
