“…Studies using other national data have concluded that black families are disproportionately represented in substantiation rates (Hill, 2007). Additionally, data from a number of state and municipal child welfare agencies have found differences in the rates of substantiation by race without adjusting for poverty or related risk factors, using a substantiation report ratio (Ards et al, 2003b; Children’s Action Alliance, 2008), substantiation-to-investigation ratio (Fluke et al, 2003), and substantiation-to-population ratio (Fluke et al, 2003; Hill, 2007; Kim et al 2011). Also, a study comparing maltreatment estimates from the National Incidence Study to CPS administrative data, found that racial disproportionality was primarily attributable to differences in substantiation rates rather than report or allegation rates (Ards et al, 2003a).…”
