New: Maps of Juvenile Arrests, 2013 and 2014

November 8, 2015

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.

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.

Maps: Rate of Change in Juvenile Arrests, 2009-2012

June 4, 2013

We are looking forward to releasing a new report about trends in Chicago juvenile arrests from 2009-2012 in the next few weeks. The report is written by students who were participants in an introductory GIS course taught by Dr. Mike Stiehl at Loyola University. The students are Ashley Cook, Zygmunt Czykieta, Paul Mack, and Chris Skrable and they created the following maps to illustrate the rate of change of juvenile arrests by district.  We have already shared information about the overall decline of 26.7% in juvenile arrests since 2009. Now we have these terrific maps to add more detail to the overall trend. We greatly appreciate our partnership with the students and are grateful for their important and excellent work.

Youth on Parole in Illinois: Maps

January 13, 2012

These maps created by Michael Stiehl from Northwestern University comprise all youth on parole in Cook County and in the state of Illinois on 3/23/11.  It is a single point in time snapshot of the population but provides a sense of which communities youth who were on paroled come from. The data also provides us with a sense of where they return to when they leave the Department of Juvenile Justice.
