Thanks to our friend Dan Cooper at the Adler School, here are some maps of 2013 & 2014 juvenile arrests in Chicago.
According to CPD, there were 17,783 juvenile arrests in 2014; down from 21,496 in 2013 (a decrease of over 17%). Since 2009 when we first began analyzing these numbers, juvenile arrests have decreased 43%.

The 21st district merged with the 2nd in March 2012, the 23rd district merged with the 19th in 2013 and the 13th district with the 12th at the end of 2012.

The 21st district merged with the 2nd in March 2012, the 23rd district merged with the 19th in 2013 and the 13th district with the 12th at the end of 2012 – this accounts for ‘missing data.’

In 2013 and 2014, Black children & youth comprised over 79% of juvenile arrests in Chicago. Black juvenile arrests outpace all other groups in each district except for the 17th and 25th districts. A closer look at rates of arrests, however, reveals that Black juveniles are disproportionately targeted in these districts too.
For example, Black juveniles represent 3.8% of the youth population in the 17th district yet they comprise 27.8% of arrests in 2014. White Hispanic juveniles represent 57.7% of the youth population in the 17th district and comprised 56.5% of arrests in 2014. The same pattern holds in the 25th district where white Hispanic youth represent 76.5% of the youth population and 57% of juvenile arrests. In both districts, white Hispanic youth are arrested at or below their population. Black youth are arrested disproportionate to their population in both districts. Blackness is the determinant factor of juvenile arrests in Chicago.
