Thirty percent of Millennials identify as LGBTQ, according to a soon-to-be released study that is based on scientific polling data. Among Christians the numbers were lower—but only slightly, with just under 30 percent of Millennial Christians identifying as LGBTQ.

The portion of the population that describes itself as gay has varied over the years, from 10 percent, based on research by Alfred Kinsey and widely promoted by the National Gay Task Force in 1977, to less than 6 percent in a recent Gallup poll. The pollster who worked on the new study, George Barna, attributes the unusually high number he found to social and news media coverage that makes it "safe and cool" for young Americans to identify as LGBTQ—whether or not it represents their actual sexual orientation.

"It's a subset of a larger issue, that this is a generation where three out of four are searching for meaning. This is a group that doesn't have a reason to get out of bed in the morning," Barna says. "Therefore, the LGBTQ identity gives them comfort. A lot of this generation claim to be moving in that direction, but there's a big difference between claiming the identity and living the lifestyle."
