While America remains a very religious country, the decades of the 21st century have seen a changing mix, particularly with the "rise of the nones" (those who claim no religious affiliation, which has been most evident among younger age cohorts). Religion in America traces significant changes, some going back to the end of World War II in 1945, much to the early 1970s, using data from public opinion polls and research by Gallup, Pew, Barna and others. The report is updated throughout the year.
