In less than 20 years, babies born to Muslim mothers are projected to modestly exceed babies born to Christian mothers, making Muslims the world’s fastest-growing religious group by 2035.
According to Pew Research Center (Pew), “Muslims are projected to be the world’s fastest-growing major religious group in the decades ahead, as Pew has explained, and signs of this rapid growth already are visible.”
Between 2010 and 2015, an estimated 31 percent of all babies born were births to Muslims. This exceeds the share of Muslims of all ages in 2015 (24%).
Meanwhile, “[t]he world’s Christian population also has continued to grow, but more modestly. In recent years, 33% of the world’s babies were born to Christians, which is slightly greater than the Christian share of the world’s population in 2015 (31%).”
Christians have also seen a “disproportionately large share of the world’s deaths (37%)” in recent years, explains Pew Research Center. This is likely due “in large part because of the relatively advanced age of Christian populations in some places.”
The relatively young and fertile population of Muslims lead Pew to project that between 2030 and 2035, more babies will be born to Muslims – 225 million, according to Pew – than to Christians (224 million), despite the fact that the overall Christian population will remain the largest of the major religions.
Within another 25 to 30 years (by 2055 to 2060) following the Muslim faith’s ascension to the world’s fastest growing religion (between 2030 and 2035), the birth gap between Christians (226 million births) and Muslims (232 million births) is projected to narrow to 6 million.
“Between 2015 and 2060, the world’s population is expected to increase by 32%, to 9.6 billion,” noted Pew. 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).
