Meet the 'nones': More Americans are religiously unaffiliated. Who are they?

• A new Pew Research Center report contained new insights into nonreligious Americans.
• The so-called "nones" have been rising for decades and now make up nearly 30% of the country.
• Pew found many nones still believe in God or another higher power and identify as spiritual.

The rise of the "nones" — Americans who report having no religious affiliation — has been happening for decades, sparking questions and concerns about what the decline in religiosity could mean for the country.
