Crime Patterns in ChicagoTweet
This will hopefully be an ongoing project in which I track various trends in Chicago crime. The goal is to use data visualization to highlight patterns in criminal activity in Chicago. I try to keep text as minimal as possible. All data used is publicly available and sourced. If you find this interesting, a list of related recommendations can be found at the bottom of the page.

Sources + Notes
1. Source, data for 2011.
2. Snowpocalypse occurred on Feb 2, 2011 and refers to the ridiculous amount of snow that shut down the city for a couple days. And trust me, it's hard for weather to shut down Chicago.
3. Spring = March, April, May. Summer = June, July, August. Fall = September, October, November. Winter = December, January, February.
4. As defined by the City of Chicago Police Department.
5. For distribution comparison purposes, radii were not held constant. Radii values given are in Total Reported Crimes.
6. As defined by the City of Chicago Police Department.
7. Black bars signify values above the mean.
8. Source, data for 2009.
9. Source and source, crime data for 2009, median income data for 2010. I make the assumption that median income in each community grew by a proportionate amount and therefore, using 2009 and 2010 data is acceptable for the sake of comparison. I mean, I was an economics major, where making broad assumptions is actively encouraged.
