A child abuse fatality occurs when a child's death is the result of abuse or neglect, or when abuse or neglect are contributing factors to a child's death. In the United States, 1,730 children died in 2008 due to factors related to abuse; this is a rate of 2 per 100,000 U.S. children. Family situations which place children at risk include moving, unemployment, and having non-family members living in the household. A number of policies and programs have been put in place in the U.S. to try to better understand and to prevent child abuse fatalities, including: safe-haven laws, child fatality review teams, training for investigators, shaken baby syndrome prevention programs, and child abuse death laws which mandate harsher sentencing for taking the life of a child.
