Analysis of information sources in references of the Wikipedia article "Muslim population growth" in English language version.
This analysis of religious switching draws on surveys in 19 countries where Muslims constitute a majority of the population. Generally, however, there are few reports of people disaffiliating from Islam in these countries. One reason for this may be the social and legal repercussions associated with disaffiliation in many Muslim-majority countries, up to and including the death penalty for apostasy. It is possible that, in the future, these societies could allow greater freedom for religious disaffiliation. The demographic projections in this report do not seek to predict the likelihood of such changes in political and social dynamics, or to model what the consequences might be.
Behind the trend: High birthrates in Asia, the Middle East, and Europe.
India and Pakistan have Muslim populations of roughly similar size, and it is not entirely clear which is larger.

There are numerous reasons why reliable data on conversions are hard to come by. Some national censuses ask people about their religion, but they do not directly ask whether people have converted to their present faiths. A few cross-national surveys do contain questions about religious switching, but, even in those surveys, it is difficult to assess whether more people leave Islam than enter the faith. In some countries, legal and social consequences make conversion difficult, and survey respondents may be reluctant to speak honestly about the topic. Additionally, for many Muslims, Islam is not just a religion but an ethnic or cultural identity that does not depend on whether a person actively practices the faith. This means that even nonpracticing or secular Muslims may still consider themselves, and be viewed by their neighbors, as Muslims.
there is no substantial net gain or loss in the number of Muslims through conversion, globally; the number of people who become Muslims through conversion seems to be roughly equal to the number of Muslims who leave the faith
