Each report represents a referral made to a county's Child Protective Services (CPS) that involves allegations of child abuse or neglect. One CPS report can involve multiple children, or multiple allegations involving the same child.
The rate represents the number of abuse and neglect reports for a given year per 1,000 children ages zero to 17 in the county in the previous year. This rate is calculated by the Department of Children and Families and presented in its reports.
Figures are from Wisconsin Child Abuse and Neglect Reports: Annual Reports, Wisconsin Department of Children and Families.
