As growing numbers of young people report struggling with mental health issues, colleges and universities across the United States are working to meet their students’ needs. But a new study suggests that one group of students is facing these issues more than any other: transgender students. And some experts worry that many schools may not be doing enough to meet their needs. Transgender people are people who no longer identify with their sex from birth. They feel they are really members of the opposite sex. Many often change their name, appearance and even undergo medical treatments to help match, or keep up with, the way they feel. In 2016, about 1.4 million Americans identified themselves as transgender. That number comes from the Williams Institute at the University of California Los Angeles’ School of Law.
