Homelessness exposes individuals and families to traumatic events which often aggravates their current circumstances. Homelessness challenges the ability to access needed resources and regain self-sufficiency. Children are particularly vulnerable to the adverse effects of homelessness. Homelessness often interrupts schooling and the development of positive peer and mentoring relationships. Homeless children frequently experience dangerous or unhealthy environments and may be more likely to experience homelessness as an adult. Communities also feel the impact of homelessness.
