The McKinney-Vento Act defines unaccompanied homeless children and youth as individuals who lack a fixed, regular, and adequate nighttime residence, and are not in the physical custody of a parent or guardian. Unaccompanied homeless youth and children include young people who have been kicked out of their homes, run away from home, and/or have been abandoned by parents or guardians. Youth who refuse to live at home are still considered to be experiencing homelessness if their living situation meets the definition under the McKinney-Vento Act.
