The Centers for Disease Control and Prevention (CDC) has released statistics and demographic data regarding the victims and perpetrators of child maltreatment. It appears that most of the data was obtained and processed through information that was provided by state child protective services agencies, so this might be only data of reported child maltreatment cases.
Of the victims, 79% were the victims of neglect, 18% of physical abuse, 9% of sexual abuse and 10% of other maltreatment such as threatened abuse, parent’s drug/alcohol abuse or lack of supervision. In 2011, 35% of the victims were younger than 3 and children younger than 1 have the highest rate of victimization (21.2 per 1,000 children). In 2011, 80.8% of the abuse was by a parent, 5.9% was by relatives other than parents, 4.4% by unmarried partners of parents and 2.9% by other unrelated adults. Again, in 2011, 45.1% of perpetrators were men and 53.6% were women.
