It's official: Europe is becoming less Christian.
An international study of demographic trends shows that Europe's Christian population is expected to shrink by about 100 million people in the coming decades, dropping from 553 million in 2010 to 454 million in 2050.
While Christians will remain the largest religious group in Europe, they are projected to drop from three-quarters of the population to less than two-thirds.
By 2050, nearly a quarter of Europeans (23 per cent) are expected to have no religious affiliation, and Muslims will make up about 10 per cent of the region's population, up from 5.9 per cent in 2010.
