Have you attended a local CAPS meeting? Check at your local police station for location and times. The CPS crime stats web page is http://gis.chicagopolice.org/. There are various other sites to look at as well such as www.neighborhoodscout.com/il/chicago/crime/ and www.chicago.everyblock.com/crime/.
No matter how much crime you find there to be in your area you will also want to check out the crime list for some area you may think of as "safe" or "better". You may be surprised to find that there is crime anywhere you look.
