Muslim population growth

In 1900, Muslims only numbered 200 million followers or 12% of the world population. This percentage increased over the last 100 years due to a higher birth rate found in Muslim majority countries and reached about 25% or 2 billion in 2025. Pew Research have estimated that the number will be around 2.2 billion in 2030 and 2.8 billion, or 30 percent of the world population, in 2050. This would mean that Islam would almost equal Christianity in terms of population.
