In India, it is well-known fact that Islam is growing massively and certain groups have even raised concern over the fast growth of Muslims.  But what is interesting is the fact that the Hinduism happens to be the fastest growing religion for a very motley set of countries.

According to the Pew Research Centre’s ‘The Future of World Religions’ report, some countries will see the doubling of the number of Hindus by 2050, all thanks to the migration of Hindus and the increase in their fertility rate. According to this report, Hinduism has become the fastest growing religion in Pakistan and Saudi Arabia.

This Report suggests that nearly 1 million Hindus are expected to move to a different region over the next four decades. There are some countries that will have double the number of Hindus by 2050 than they did in 2010. In Saudi Arabia, Hindus currently make up about 1.1% of the population. The report also claimed that the total population of Hindus will go up to 1.6% by 2050, largely on the back of migration.

While the fertility rate of all religions globally is about 2.5 children per woman, and just 2.1 in the Asia-Pacific region, the fertility rate of Hindu population in Pakistan is 3.2, which happens to be the exact same as the Muslim fertility rate in India.

The third country in Asia where Hinduism is growing is Thailand, where it is slated to go up from 0.1% of the Thai population to 0.2% by 2050. Europe happens to be even more interesting, for Hindus. The four countries that turn up here are Ireland, Belgium, Italy and Greece, all places where Hindus are expected to grow primarily because of migration and the resulting fertility rate.

Reddit user KaliKwad took the data from the report and turned it into a map of the world’s fastest-growing religions. The map is based on relative, not absolute, numbers, so the religion picked is the one that will have the biggest jump in its share of each country’s population.

Here is the map for Asia:

It is evident that Islam is growing fast everywhere. The Pew Research Centre had also claimed that the Muslim religion is expanding significantly in Hindu-dominated country. According to it, by 2050, Muslims will surpass Hindus as the largest religious group in the India-Pacific region from having just 24.3% share of the population up to nearly 30% mid-way through the century.

According to 2011 census, total population of Muslims in India was 13.4 %. The latest report claimed that the same number will increase to 18.4% by 2050.

Buddhism, another religion that originates in India, is also growing rapidly in Europe, taking the top spot in Norway, Sweden, the Netherlands and Austria.
