A number of studies of homeless youth in big cities put forth a startling statistic: Depending on the study, somewhere between 30 and 40 percent of homeless youths identify as lesbian, gay, bisexual or transgender.
It’s largely because gay youths are more often kicked out of their homes than straight youths. And even if they are not kicked out, they may feel so uncomfortable that they leave.
In New York City, nearly 4,000 young people are homeless every night — many of them gay.
