About the data: Cyprus' Muslim populaton is based on estimated 18 percent of the total population until 1974. Kettani is in general used for data from 1950 up to 2010, Pew Reseach Center for present day data and projections.
All population estimates is based on data from UN (medium population growth projections), with one exception: Pew Reseach Center had significant higher population datas than the UN for most Western countries in the high migration scenario (Einstein-fact: High immigration results into a higher population), so for the high migration scenario, I have calculated a population out of Pew's scenario data. Using UN's data for the high migration scenario would have resulted into a misleading presentation with a far higher density of Muslims than suggested by Pew Research Center.
A method simulating exponential growth is used in the interpolations between the datapoints.
