A new survey of young Americans aged 13 to 20 years old (also known, in marketing-speak, as "Generation Z") has found that they are far more open-minded and permissive than their older millennial counterparts when it comes to issues of gender and sexuality. According to a report by trend forecasting agency J. Walter Thompson Innovation Group, only 48% of Gen Zs identify as exclusively heterosexual, compared to 65% of millennials aged 21 to 34.

"We did a survey of Gen Z for a report released in May 2015 and found that 81% said that gender doesn't define a person as much as it used to," said Shepherd Laughlin, the director of trendspotting at J. Walter Thompson.

"That was an intriguing statistic that got a lot of attention in the media, but we weren't sure quite what it meant: Were they just saying, for example, that men or women could pursue any career they wanted to? Or did this reflect the more radical idea that gender itself isn't as important to personal identity as it used to be, or that gender shouldn't be seen as a binary? This new research shows that the latter idea is gaining significant traction among Gen Zers."

"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."
