IDJJ commitments<br />
In FY07, black youth ages 13 to 16 were committed to IDJJ almost three times their<br />
representation in the general youth population (RI=2.88). Hispanic youth were underrepresented,<br />
committed at a level 44 percen t less than their representation (RI=0.56), <strong>and</strong> Asian<br />
youth were under-represented with zero commitments in FY07. White youth were committed at<br />
a level 43 percent less than their representation (RI=0.57). Table 8 shows the representation<br />
indices for the state by race <strong>and</strong> ethnicity for FY07<br />

Relative rate index<br />
In an attempt to address the weaknesses of the RI, OJJDP convened a workgroup that was<br />
charged with identifying a more effective measure of disproportionate minority contact. Using<br />
the same data needed to calculate the representation index, the workgroup developed a relative<br />
rate index (RRI). The relative rate index compares the rate at which a minority group is<br />
represented at a particular juvenile justice stage to the rate a reference group is represented at the<br />
same stage. The RRI is determined by calculating the rates of both the minority group <strong>and</strong> the<br />
reference group at the juvenile justice stage of interest.<br />
