Homeless youth are defined in this report as unaccompanied young people ages 14-25 that do not have a safe, stable place to live. Youth often leave home or are forced out due to physical and sexual abuse, substance abuse by a parent, and long-term family economic problems. Pregnant and parenting teens, LGBTQ (lesbian, gay, bisexual, transgender, queer) youth, and current and former wards are disproportionately represented in the homeless youth population. During the 2009-2010 school year, the Chicago Public Schools identified 3,682 unaccompanied homeless youth in school. Based on CPS data, data from shelters, and data from other research on homelessness, Chicago Coalition for the Homeless has developed a methodology to estimate total numbers of homeless youth, children, and adults each year including those living doubled up. According to this estimate, there were a total of 11,471 homeless youth ages 18-21 in Chicago during the 09-10 school year. This includes youth who were not in school or were not identified by the schools. Shelter and housing programs in Chicago do not come close to meeting the need for housing for young people. A survey conducted for this report found that the eight programs providing shelter and housing to homeless youth turned away 4,775 requests for housing from youth in a year. When youth are not able to access shelter they are extremely vulnerable to physical and sexual victimization on the streets.
