An increasing number of young adults identify as nonheterosexual and noncisgender, according to a new global survey from Ipsos. The results, released Wednesday, are based on internet surveys of more than 19,000 people in 27 countries ages 16 or 18 (depending on the country) to 74. The surveys were conducted in the languages of each country. Respondents in Generation Z, which includes people born after 1997, were nearly four times as likely than those over 40 (4 percent compared to 1 percent) to identify as transgender, nonbinary, gender-nonconforming, gender-fluid or “in another way.” They were also the age group most likely to identify as something other than heterosexual. Overall, 9 percent of respondents identified as lesbian, gay, bisexual, pansexual, omnisexual or asexual; for Generation Z, the figure doubles to 18 percent.
