The number of Muslims grew more than all other religions combined, making Islam the fastest-growing religion over the decade between 2010 and 2020, a new study by the Pew Research Centre has found.
Pew’s Global Religious Landscape study, released on Monday, attributed the growth of Islam to natural demographic growth. It also concluded that at the global level, Muslim population change had “little to do with people converting into or out of the faith”.
“Muslims have more children and are younger, on average, than members of any other major religion,” the study said.
“Based on data for the 2015-2020 period, we estimated a Muslim woman would have 2.9 children, on average, in her lifetime, compared with 2.2 children per non-Muslim woman,” the report added.
The study, which examined how global religious composition changed between 2010 and 2020, concluded that while Christianity remained the world’s largest religion, comprising 2.3 billion people, the gap between the proponents of Islam and Christianity continued to shrink.
According to the study, the world’s Christian population decreased by about 1.8 percent since 2010.
The increase in the number of Muslims in the world was concentrated primarily in Muslim-majority countries.
The percentage of religiously unaffiliated people grew particularly steeply in the US, with an increase of 97 percent from 2010.
The majority of religiously unaffiliated people live in China, where 1.3 billion people are not affiliated with any religion.
Pew’s analysis found that Christians were still a majority in 60 percent of all countries and territories surveyed. However, Christianity decreased by at least five percent in 40 countries, while only significantly increasing in one.
Pew attributed part of this decline to people leaving Christianity, by measuring the number of adults who changed their religion to one different than the one they were raised in.
Both Buddhism and Hinduism also saw more adults leave their religion than join it.
Islam was the only religion where more adults joined than left. (Middle East Eye)
