According to the Pew Research Center's projection for the year 2100, if current demographic trends continue, Islam will be the world's largest religion with a population of 3.91 billion. Islam will be followed by Hinduism and Christianity, while atheist/agnostic, deist, and Judaism will be among the belief groups with lower population rates.
The phenomenon of religion, which has shaped the social and cultural structure of societies throughout history, has become a topic of discussion again with the global changes experienced in the 21st century. Increasing population mobility and demographic differences have brought projections regarding the future of belief groups to the forefront.
ISLAM IS IN FIRST PLACE
The Pew Research Center, based in the USA, shared global population forecasts for religions for the year 2100. According to the research, if current demographic trends continue, Islam will be the world's largest religion by the end of the century. Projections suggest that Islam is expected to reach 3.91 billion adherents by 2100. Hinduism follows with 3.78 billion and Christianity with 3.1 billion.
OTHER BELIEF GROUPS
The research predicts that the number of those identifying as atheists or not affiliated with any religion will be 1.09 billion, deists will be 224.2 million, and Jews will be 19.6 million. Pew's data is based on factors such as birth rates, age distribution, and regional demographic changes. Experts emphasize that such projections are calculated based on current trends and may change depending on long-term socioeconomic developments.
