The United States of America is a large, secular nation of about 325 million people1. Because it was founded as a nation of immigrants, there is now considerable religious diversity across the country2. The majority identify as Catholic at 83%, but with many various sects included3. Another 13% of the population claims to be non-religious3. The final 4% is made up of many different religions, most notably including Judaism, Muslim, and Buddhist3.
Religion remains important to many Americans, but over the past several years, the population as a whole has become less religious4. Older demographics are much more likely than the youth to report being very religious4.
