No one religious affiliation was associated with child marriage, according to a 2007 ICRW study. Rather, a variety of religions are associated with child marriage in countries throughout the world.

I was quoting the website. It wasn't my opinion that "no religious affiliation was associated with child marriage", it was their findings after their research. I've fed you the data on the religious breakdown below. An uncritical superficial look would register that Islam is a majority religion in some of these countries. However, you need to consider that child marriages were happening in those countries across all religious groups, not exclusively the Muslims. What is the GDP for each country? What about access to education? How do those correlate? According to the ICRW research there is a high correlation. I see a lot of impoverished African countries. Yes, some of impoverished nations on this list happen to have Muslim majorities, but as you can see from this list, a lot do not and they still see high rates of child marriage. If the issue was Islam, shouldn't all Islamic countries be on this list instead of countries with few to no Muslims?
