NEW YORK — In recent years, Christians have had more babies than any other religious group worldwide. But by 2035, Muslims are projected to experience the higher birth rate, putting the world’s two largest religions on track to have a near equal share of the global population by 2060, according to a demographic analysis released Wednesday.

With 2.3 billion adherents, Christians are the world’s largest religious group and are expected to remain so for several decades, according to the Pew Research Center report “The Changing Global Religious Landscape.” Muslims have 1.8 billion followers. But a Muslim baby boom is expected to narrow that gap. By 2060, Muslims are expected to comprise 31 percent of the world population, with nearly 3 billion people, while Christians will make up about 32 percent, or 3.1 billion people.

The new report builds on a Pew study two years ago that found Islam is the world’s fastest-growing major faith.

According to the latest report, 223 million babies were born to Christians from 2010 to 2015, compared to 213 million babies born to Muslims in the same period. By 2035, the number of babies born to Muslims is projected to exceed those for Christians, narrowly at first, then eventually by millions.

Christianity is growing especially strongly in sub-Saharan Africa. By 2060, 4 in 10 Christians will live in Africa, according to Pew’s projections. At the same time, in many European countries, such as Germany, the death rate for Christians is exceeding births, a trend that is expected to continue.
