Nearly one-in-four Hispanic adults are now former Catholics, the Pew Research Center reports. According to its 2013 National Survey of Latinos and Religion, a majority of America's 35.4 million Latino adults (55 percent) identify as Catholic. Roughly 22 percent are Protestant, most of whom identify as born-again or evangelical. And 18 percent are religiously unaffiliated. In 2010, Pew Research polling showed two-thirds of Hispanics identified as Catholics, meaning Catholic identification has dropped 12 points in the past four years.
