According to the data, an estimated 31 percent of babies born in the world between the year 2010 and 2015 were of Muslim parents, which exceeded the 24 percent share of Muslim population in the world.
Islam is already the world's fastest-growing religion, because even though Christian births still outpace Muslim births, more Christians are dying in European nations such as England, Germany, Italy and Russian Federation, than are being born.
In recent years 33 per cent of the world's babies were born to Christians, slightly more than the 31 per cent Christian share of the world's population in 2015.
Meanwhile, the global Muslim population increased by more than 150 million people between 2010 and 2015, to 1.8 billion.
Despite a relatively young and fertile Christian population in sub-Saharan Africa, Christians have accounted for a disproportionate 37% of the world's deaths in recent years. This will happen because Christians have had and will have fairly high number of population in the advanced age group. By the 2055 to 2060 period, that birth gap between the two groups is expected to approach six million, with 232 million births among Muslims and 226 million births among Christians, it added. This natural decrease in Europe's aging Christian population was unique compared with Christians in other parts of the world and other religious groups.
"In contrast with [the] baby boom among Muslims, people who do not identify with any religion are experiencing a much different trend", said Pew.
Christian mothers are having more babies than to anyone else now. In Germany, the UK, Italy, Russia and France, there were at least 250,000 more Muslim births than deaths in each country over the period. Religious "nones" were the third largest demographic, comprising 24 percent of the world's population.
The centre said there are important regional differences in birth and death trends for some religious groups.
The report clarifies that just because it tallies babies born to mothers of certain religions, that doesn't mean that those babies will remain in the religion their mother is affiliated with.
But while Christians matched the average, 34 per cent of the Muslim population was under 15. By 2060, 9% of the global unaffiliated population will live in the United States alone, according to the projections.
Pew experts say they allowed for conversion rates, but maintain that birth and death rates will have a far larger impact on religious populations.

And by 2060, the total number of Muslims and Christians is expected to near parity, with the number of Muslim individuals reaching approximately 3.0 billion (31% of the world's population) and the number of Christian individuals reaching approximately 3.1 billion (32% of the world's population).
