Generally, there are few reports about how many people leave Islam in Muslim majority countries. The main reason for this is the social and legal repercussions associated with leaving Islam in many Muslim majority countries, up to and including the death penalty for apostasy. However, the report also suggest that in future, it is also possible that these societies could allow for greater freedom to religiously disaffiliate.[218] On the other hand the increasingly large ex-Muslim communities in the Western world that adhere to no religion have been well documented.[219] A 2007 Center for Strategic and International Studies (CSIS) report argued that some Muslim population projections are overestimated, as they assume that all descendants of Muslims will become Muslims even in cases of mixed parenthood.[196] Equally, Darren E. Sherkat questioned in Foreign Affairs whether some of the Muslim growth projections are accurate as they do not take into account the increasing number of non-religious Muslims.
