The BBC supplies Ten Things We have Learnt About Africa , summarizing a Pew report on sub-Saharan African religious and moral beliefs, and their material well-being as well. Religious belief was unsurprisingly high roughly 80% believing in God in some way though that is not an unmixed blessing, since some of those beliefs include the re-establishment of the Caliphate in their lifetime (over 50% of Muslims in Nigeria) and the imposition of Sharia Law (about 40% of Muslims in Nigeria), neither of which bode well for Christians.
Much of the full report, Tolerance and Tension: Islam and Christianity in Sub-Saharan Africa , can be found here .
