A recent report of Pew Research Center featured a list in the form of two tables. The tables feature the Christian and the Muslim populations from all over the world with differences in diversity and concentration of the two major religions, in different countries, now and projected for 2060.
The population of Muslims is highest in Islam’s important centers. Approximately 65 percent of Muslims reside in nations with the ten most significant Muslim populations. To put this data in perspective, only 48 percent of the global Christian population live in countries having the ten largest Christian communities. About 52 percent of global Christians reside in nation states where the dominant religion by population is not Christianity. The same statistic can be applied to only 35 percent of global Muslims.
When it comes to absolute terms, 1.2 billion Christians and 609 million Muslims live where their faith is not in the top 10 countries. Pew Research Center India is a unique country in the sense that despite housing the world’s second-largest Muslim population, the number of adherents towards Islam (15 percent of the Indian population) nothing compared to the number of people identifying themselves as Hindu. Nigeria is another country hosting both the sixth most significant Christian population in the world (87 million) and the fifth largest global Muslim population (90 million).
