Marquan Ellis was evicted from his home in Las Vegas, Nevada when he was 18.
His mother battled with a drug and gambling addiction while he stayed at his godmother's house. But he couldn't stay there forever.
He found his way to the Nevada Partnership for Homeless Youth where he enrolled in the independent living program.
He isn't sure what he would have done if he hadn't found that program: "I would have been on the street looking for someone to help, looking for my next meal, looking for my next shower, looking for my next place to sleep."
Like Ellis, some 4.2 million young people experience unaccompanied homelessness in the course of a year, according to a new study from Chapin Hall a research center at the University of Chicago.
