Understanding the Pew Forum on Religion and Public Life’s religious affiliation study
The Pew Forum on Religion and Public Life recently released a global study of religion whose findings have appeared in newspapers and social media everywhere. Using more than 2,500 censuses, surveys and population registers, it found that 84 percent of adults and children around the globe are religiously affiliated; the median age of two major groups, Muslims (23 years) and Hindus (26), is younger than the world’s overall population (28). Jews have the highest median age (36) of the groups studied.
