From trust in government to views of climate change, here are some of Pew Research Center's most memorable findings of the year.
India is projected to have 310 million Muslims (11% of the global total), making it the country with the largest population of Muslims in the world.
The number of Christians in Europe is forecast to drop by about 100 million by 2050, while the share of Muslims and smaller religious minorities will increase.
If current demographic trends hold, by 2050, Muslims are projected to be more numerous in the U.S. than people who identify as Jewish on the basis of religion.
Demographer Conrad Hackett explains how he and his team put together our major new report and why it differs from past efforts to predict religious change.
The religious profile of the world is rapidly changing, driven primarily by differences in fertility rates and the size of youth populations among the world’s major religions, as well as by people switching faiths. This table details the estimated religious composition of 198 countries and territories for 2010 to 2050.
What will the world’s religious landscape look like a few decades from now?
As of 2010, nearly a third of the world's population identified as Christian. But if demographic trends persist, Islam will close the gap by the middle of the 21st century.
