1. Christianity is
growing faster than the population.
Globally,
Christianity is growing at a 1.27% rate. Currently, there are 2.5 billion
Christians in the world. The world’s population, 7.7 billion, is growing at a
1.20% rate.
Islam
(1.95%), Sikhs (1.66%) and Hindus (1.30%) are the only religious groups growing
faster than Christianity, though followers of Jesus outnumber every other faith
and are predicted to continue to do so at least through 2050.
2. Pentecostals and
Evangelicals are growing the fastest and are still picking up speed.
Among
Christian groups, Pentecostals (2.26%) and evangelicals (2.19%) are growing
faster than others.
They
are both also growing faster than they did just two years ago. In 2017,
Pentecostals’ growth rate was 2.22% and evangelicals was 2.12%.
3. Atheism has peaked.
There
are fewer atheists in the world today (138 million) than there were in 1970
(165 million).
Since
2000, atheism has rebounded slightly—only by 0.04%—but it is expected to
decline again and fall below 130 million by 2050.
Agnosticism
has maintained a small growth rate of 0.42%. After reaching 716 million this
year, however, it is expected to drop below 700 million by 2050.
