According to Google’s approximation of the city populations :

2012 Chicago Crime Data From :

https://data.cityofchicago.org/
“Data is extracted from the Chicago Police Department’s CLEAR (Citizen Law Enforcement Analysis and Reporting) system.”

2012 Los Angeles Crime Data :

http://www.lasdhq.org/sites/CAASS/desc.html
Los Angeles Count Sherrif’s Department

Now I have two sets of data. I have a (Primary Crime Type or Category of Crime) and Frequency;
for both Chicago and Los Angeles.

Here are what they look like.

CPD labels their crimes differently from the LAPD.

Here is how I will be correlating some of the crimes between the two cities. Comparing the Chicago classifications to Los Angeles.

Next I will manicure my data into a Google Column Chart acceptable JSON object.
