Children who lack a stable home are vulnerable to a number of adverse outcomes. Some threats, such as poverty and hunger, may precede episodes of homelessness; others stem directly from living without a home. Homeless children are more likely than other children to have moderate to severe acute and chronic health problems, and less access to medical and dental care. Symptoms of asthma, hyperactivity/inattention, and behavior problem are more prevalent among this group. Children without stable homes are more than twice as likely as others to repeat a school grade, be expelled or suspended, or drop out of high school. A quarter or more of homeless children have witnessed violence, and more than half have problems with anxiety and depression. Family homelessness may result in children’s separation from their parents—either because children are formally placed in foster care, or because parents leave children in the care of relatives and friends.
