In 2003, an estimated 906,000 children were victims of abuse and neglect. Neglect was the most common form of maltreatment, with 60.9 percent of child victims suffering from neglect in 2003. Neglect was followed by physical abuse (18.9 percent of child victims), sexual abuse (9.9 percent of child victims), and psychological maltreatment (4.9 percent of child victims). In 2003, approximately 1,500 children died because of abuse or neglect.29 The largest percentage of perpetrators (83.9 percent) was parents, including birth parents, adoptive parents, and stepparents.30 How do fathers compare to mothers in the perpetration of child maltreatment? As discussed earlier, Federal data derived from CPS reports in 2003 indicate that in 18.8 percent of the substantiated cases, fathers were the sole perpetrators of maltreatment; in 16.9 percent of the cases, the fathers and the mothers were perpetrators; and in 1.1 percent of the cases, the father acted with someone else to abuse or neglect his child. Mothers were the sole perpetrators in 40.8 percent of the cases and acted with someone besides the father in 6.3 percent of the cases.31 This means that fathers were involved in 36.8 percent of child maltreatment cases and that mothers were involved in 64 percent of child maltreatment cases. Additionally, more than one-half of the male perpetrators were biological fathers, and, although recidivism rates were low, biological fathers were more likely to be perpetrators of maltreatment again than were most other male perpetrators. Th is may be due in part to the lack of permanence between a mother and her boyfriend or that the perpetrator may be excluded from the household before recidivism can occur.32 Mothers are almost twice as likely to be directly involved in child maltreatment as fathers.
