A secondary analysis of the 2001 national data from the Canadian Incidence Study of Reported Child Abuse and Neglect (CIS) is utilized to explore and contrast the maltreatment experiences of Aboriginal children with and without developmental delays reported to child protection services. Both the extent and the typologies of maltreatment for these two groups of children are investigated. In addition, characteristics of the child, the alleged perpetrators, and socio-economic conditions of the child and her/his family are reported. A review of relevant literature reveals a notable dearth of information in this area despite the overwhelming number of Aboriginal children and children with disabilities in receipt of child welfare services. This analysis is a preliminary attempt to address this void and to identify areas for future research.
