new muslims around the world

With regard to the third question the main reason for the increase in muslim adherents is as a result of the massive increases in population of Islamic countries, a consequence of the vast technological and medical advances achieved by the, ironically, western, i.e. nominally Christian nations, rather than converts to Islam from some other religion. Of the few that do convert to islam, it is alleged that 4 out of every 5 is female, who have more likely a desire to please their boyfriends rather than Allah. They usually abandon islam when the relationship ends. On the other hand Christianity is exploding in Africa and China. In reality islam is dying and no wonder. It is extremely violent, mysoginistic, intolerant and has no future in the modern world.

I don't mean to rain on your parade but the questions you are asking here request a lot of research and the numbers may not be as accurate as you expect.

To answer your question number 3, I think there are about 2.9% new muslims every year. The world population is only growing at 2.3%

6- One of the main reason people convert to Islam is because they see in what they do not see in other religions. Islam to new converts is a religion that preaches peace and tolerance even with all what some are doing to falsify the image of Islam.
