A new report by trend forecasting agency J. Walter Thompson Innovation has found only 48 percent of Generation Z kids (that is, 13 to 20 years old) identify as exclusively heterosexual, meaning persons who identify as something other than straight make up a majority of future generations.

The number is markedly different when compared to millennials aged 21 to 34, of which 65 percent identified as exclusively heterosexual.

The findings of the study will reportedly be released at a SXSW panel on Friday. In the meantime, Vice reports:

On a scale of zero to six, where zero signified "completely straight" and six meant "completely homosexual," more than a third of the young demographic chose a number between one and five, indicating that they were bisexual to some degree. Only 24 percent of their older counterparts identified this way.

Fifty-six percent of 13-to-20-year-olds said that they knew someone who went by gender neutral pronouns such as "they," "them," or "ze," compared to 43 percent of people aged 28 to 34 years old. Over a third of Gen Z respondents also strongly agreed that gender did not define a person as much as it used to. This figure dropped to 23 percent among millennials who were 28 and up.

Those belonging to Generation Z also rejected the gender binary while shopping—only 44 percent said they always bought clothes designed for their own gender, versus 54 percent of millennials. But they also felt strongly that public spaces should provide access to gender neutral bathrooms, with 70 percent of Gen Zs coming out in support of the move compared to 57 percent of 21–34-year-olds.

Shepherd Laughlin, director of trendspotting at J. Walter Thompson, said the sea change could perhaps be attributed to the Internet, mainly sites like Tumblr and Twitter.

"Millennials are quite open when it comes to gender identity, generally, but they haven't been exposed to the range of vocabulary and nuance around this that Gen Z has become accustomed to, especially when it comes to discussions on online platforms like Tumblr," Laughlin said. "I think that as Gen Zers eventually enter the workplace and interact more with millennials as adults, millennials will gain a better understanding of these issues, and the gap will narrow."
