A Future On World Religions And Trends: Is Hinduism The Fastest-Growing Religion In Pakistan And Saudi Arabia?

It is common enough knowledge that Islam is growing massively in India. Sure, the alarmist concerns about Muslims overtaking Hindus are overblown, but the religion is still expanding singificantly in India – as evidence by the Pew Research Centre's conclusion that by 2050, India will have the largest Muslim population of any country in the world. 

Beyond India too, Islam's ranks are swelling. But what that same report also shows is that Hinduism happens to be the fastest growing religion for a very motley set of countries.

One of a Reddit user took the data from the Pew Research Centre's The Future of World Religions report, and turned it into a map of the world's fastest-growing religions.
