You can check these two websites for crime reports, http://chicago.everyblock.com and http://gis.chicagopolice.org/CLEARMap/startPage.htm
but you should then compare to addresses in wealthier neighborhoods just to get an idea of the amount of crime in Chicago. It's a lot, and still, most people will never experience it. All large cities suffer from disproportionate crime due to density, and disparity in income levels, but again, there is a good chance you will never see it. The area you are in has changed a lot over the last several years. And you are practically on the IIT campus which has it's own security AND you are down the street from Chicago Police Headquarters.
Bronzeville, the neighborhood you are in, has a lot of history in Chicago, and there are still some gang problems but it's not like you need to worry about a drive by in front of your building. You will find new developments all the way to the lake, and heading south toward Kenwood and Hyde Park. And unlike Miami, I think you'll find the people in the area friendly and genuine.
Five minute bike ride and you're at 31st beach. Not many people in Chicago can say that. And all the new bars of the South Loop. Pilsen and Bridgeport are really close.
Your main issue will be if you become a Cubs fan. Don't hang that flag outside your window.
