The perspective of key players such as caseworkers and community facilitators on the reasons for the overrepresentation of Black youth in child welfare is little known. This study explores the reasons why Black youth are overrepresented in child welfare in Ontario (Canada) through the perspectives of caseworkers and community facilitators. We analyzed four focus groups: two with child welfare caseworkers from a Children’s Aid Society (CAS) and two with community facilitators. We used a general inductive method for the content analysis of the focus groups with N-Vivo, without being guided by prior assumptions or hypotheses. This study highlighted seven reasons why Black youth are overrepresented in child welfare, according to CAS caseworkers and community facilitators: lack of diversity among CAS caseworkers, disciplinary practices, mental health, insufficient community support networks, poverty, racism, and culture. These findings support implications for policies and practices to reduce and eliminate the overrepresentation of Black children in child welfare.
