The statistics:

A download of source data on the investigatory stop reports is available at the Chicago Police Department's website.

• Despite the decrease in total number of stops, the racial breakdown of individuals stopped has remained relatively stable.
• We continue to see that more than 70% of stops are of Black people, while less than 10% are of white people. Revised App. B, p. 32, Table 4.
• We now have data on how many stops lead to frisks, as well as how many frisks actually result in a weapon being found.
• Over 1/3 of all individuals stopped were also frisked. Revised App. B, p. 38, Table 10.
• Of those who were frisked, nearly 73% were Black. Only 5% were white. Revised App. B, p. 37, Table 9.
• For Black individuals, weapons were recovered just over 2% of the time, while for white individuals, weapons were recovered about 4% of the time. Revised App. B, p. 40, Table 12.
• In other words, Black individuals were more likely than white individuals to be frisked after a stop, Revised App. B, p. 38, Table 10, yet white individuals were more likely to be found with a weapon, Revised App. B, p. 40, Table 12.
• Overall, weapons were found in only 2.5% of frisks.Revised App. B, p. 40, Table 12.
