This factsheet provides data on the prevalence of suicide in the United States and information about common risk factors for the general population and the increased risks among homeless populations. The National Health Care for the Homeless (HCH) Council developed this factsheet as part of a series related to emerging issues in the HCH field.  It includes data from a 2017 study that found school-age children and youth who are homeless are three times more likely to attempt suicide than their housed peers. The factsheet provides resources for additional information and support, including the National Suicide Prevention Lifeline. A list of references for the data sources is also provided.
