Over the past few weeks, Pew Research has released its findings from two major studies on the religious composition of various populations. In April, the center released “The Future of World Religions: Population Growth Projections, 2010-2050,” which projects the religious makeup of future global populations based on current statistics, including “age, fertility, mortality, migration and religious switching for multiple religious groups around the world.” Released just last week, the second study titled, “America’s Changing Religious Landscape” is an analysis of the current religious composition of the U.S. population based on data collected in 2007 and 2014. Both reports have been generating some buzz, as the numbers and projections suggest marked changes in religious populations. Looking at the American study first, Pew summarizes its finding in the first sentence:
The Christian share of the U.S. population is declining, while the number of U.S. adults who do not identify with any organized religion is growing.
