We are pleased to release the 3rd edition of our Arresting Justice report. Since 2011, we have published data about juvenile arrests in Chicago.

Today, we share juvenile arrest data from 2013 and 2014.


Key Findings of the Report:

Total Number of Juvenile Arrests (17 & under) in 2013: 21,496
Total Number of Juvenile Arrests (17 & under) in 2014: 17,783
The number of juvenile arrests decreased by over 17 percent from 2013 to 2014. Since 2009 when we first began analyzing these numbers, juvenile arrests have decreased 43%.
While Blacks represent 37% of the 0-17 youth population, they accounted for over 79% of juvenile arrests in Chicago in 2013 and 2014.
While Latin@s represent 40% of the 0-17 youth population, they accounted for over 18% of juvenile arrests in 2013 & over 17% in 2014.
Males were over 83% of juvenile arrests in 2013 & 2014.
In 2013 & 2014, 15 to 17 year olds accounted for over 80% of juvenile arrests (they represent 16.6% of Chicago’s youth population).
Most juvenile arrests were for misdemeanor offenses in 2013 & 2014. The top three in 2014 were miscellaneous non-index offenses, drug abuse violations and simple battery.
Based on the data, in 2014, 48.3% of juvenile arrests were referred to court while 19.1% resulted in detention. 25.4% of juvenile arrests resulted in informal station adjustments and 3.85% in formal station adjustments.

Discipline Practices in Chicago Schools: Trends in the Use of Suspensions and Arrests

August 24, 2015

Suspension rates in Chicago Public Schools have declined markedly but still remain very high, particularly among the system’s most vulnerable students. In the 2013-14 school year, 16 percent of CPS high school students received an out-of-school suspension (OSS), down from 23 percent in 2008-9. Still, 24 percent of high school students with an identified disability and 27 percent of high school students in the bottom quartile of achievement received out-of-school suspensions in 2013-14. Suspension rates for African American boys in high school remain particularly high, with one-third receiving at least one out-of-school suspension.

This report finds that at the same time out-of-school suspension rates have declined, students and teachers across the district report feeling safer. At the high school level, student perceptions of safety and teacher perceptions of order have been improving since the 2008-09 school year; this is also the period during which OSS rates declined in high schools.

The report tracks suspension and arrest rates in Chicago schools over a six-year period, as CPS implemented a number of policies intended to improve school climate and reduce the amount of instructional time lost to suspensions. The policies are part of a larger national push to move away from “zero-tolerance” discipline policies and reduce the use of practices that remove students from the classroom. A follow-up report will examine more closely the relationship between reductions in suspensions and school climate, particularly in schools that had the highest suspension rates.

Key findings from the report include:

Suspension rates are strongly related to students’ prior test scores, their race, and their gender. African American students are much more likely to be suspended than students of other races/ethnicities. Suspension rates are particularly high for African American boys in high school. About one-third of African American boys in high school (33 percent) received an OSS in 2013-14. In comparison, 13 percent of Latino boys in high school and 6 percent of white/Asian high school boys received an OSS in 2013-14. African American girls also have high OSS rates in high school, at 23 percent in 2013-14. This compares to high school OSS rates of 6 percent for Latina girls and 2 percent for white/Asian girls.

Students with low entering test scores are also much more likely to be suspended, and lose instructional time, than those who begin the year with high test scores. In high school, 7 percent of students with the highest test scores received an OSS in the 2013-14 school year. In contrast, about a quarter of high school students with the lowest incoming test scores received an OSS.

The decline in high school OSS rates has been accompanied by a doubling of in-school suspension (ISS) rates among African American high school students. In the 2013-14 school year, 15 percent of high school students received at least one in-school suspension, up from 11 percent in 2008-09. Thus, the rise in in-school suspensions is counter-balancing the decline in out-of-school suspensions. In-school suspensions are given more frequently to African American students than students of other racial/ethnic groups. ISS rates nearly doubled for African American high school students between 2008-09 and 2013-14, but remained the same for other student groups.

Most suspensions in high schools result from acts of student defiance rather than violence or illegal behavior. At the high school level, about 60 percent of out-of-school suspensions and almost all in-school suspensions result from defiance of school staff, disruptive behaviors, and school rule violations. While administrators interviewed for the study recognized fights as a primary concern in their schools, 27 percent of out-of-school and 7 percent of in-school suspensions in high school are for physical conflict or threats to safety. Most suspensions result from conflicts that involve no physical harm.

Profile of Illinois Incarcerated Youth – August 2014

September 18, 2014

The Illinois Department of Juvenile Justice publishes monthly data about the population in its youth prisons. You can read August data here (PDF).

“At the end of the August, the population in the juvenile prisons was 726 – a new record low. Less than 100 of those youth are in for murder (8) or Class X felonies (74) – the offenses that are not eligible for Redeploy Illinois. The rest of the offenses are all either Redeploy eligible or parole violations – 18 are in for misdemeanors and 90 are in for Class 4 felonies (the least serious felony classification). 42% (306) are from Cook County, which has still not adopted Juvenile Redeploy IL.”

Trends in CPS Suspensions, Expulsions, Arrests (2010-2014)

August 5, 2014

On July 2, 2014, the Mayor’s Office, Chicago Public Schools and the Chicago Police Department convened a roundtable with Attorney General Eric Holder to discuss improvements in school safety since the 2010-2011 school year. They provided media members and other assembled guests with a handout that listed student safety outcomes.

Compared to the 2010-2011 School Year, this school year (2013-2014) there were:

• Over 27,000 fewer out of school suspensions – a 33% drop in out of school suspension rate
• Nearly 1,300 fewer CPS students referred for expulsion – a 37% drop in referral for expulsion rate
• Over 1,000 fewer in-school arrests of CPS students – a 35% drop in the in-school arrest rate

CPS Suspensions and Expulsions Data Summary

June 2, 2014

We worked very diligently over the past of couple of years with our allies as part of the Chicago Student Safety Act Coalition to push the Chicago Public Schools to improve their discipline data transparency.

In late February 2014, for the first time ever, the District published school discipline data on its website.

Today, we are sharing a few summaries of CPS discipline data for public use.

1. Suspensions & Expulsions (Citywide SY12-SY14S1) – this is summary data that is available on the CPS website as an EXCEL document. You can also find discipline data for individual schools on the site.

2. CPS Suspensions and Expulsion Data Summary SY11-13 (PDF)- this is summary by the Office of College and Career Services (which we have reproduced).

3. CPS Suspensions and Expulsions SY12-13REV (PDF) — This is a fact sheet summary of discipline data that includes arrests.
