"According to a 2014 study from the Pew Research Center, the percentage of Catholics went from 90 in the 1960s to 69 at present.

U.S. Catholics at large, but Hispanics in particular, are seeing a similar tendency. Among millennials, they represent close to 60 percent of the total, yet a 2013 study from Pew shows that one in four adult Latinos are now “former” Catholics.

As a footnote, some observers pointed out last September, as Francis was headed to the United States, that outreach towards the Latino community was one of the reasons he chose to deliver 14 of his 18 addresses in the country in his native Spanish."

Younger Catholics not identifying as such, rather “Nones”.
