New Research Connects Heat, Weekends with Aggressive Crimes and Shootings in Chicago
"...A new Arizona State University and Purdue University research study examines this phenomenon.  In it, the authors sifted through data on almost 6 million reported crimes in Chicago between 2001 and 2014 to try to tease out factors that might promote or suppress various types of crime....

The authors found a strong dependence of aggressive crimes on temperature, where higher temperatures than usual - especially in June and July - were associated with a sharp uptick in those crimes....

'The confluence of hot summer days and weekends is thus a perfect storm that results in spates of shootings,"  ...Conversely, the authors found rainy and windy days tended to suppress crime...

The authors also found that holiday effects are important to many types of crime.  Aggressive crime goes down significantly on Christmas and Thanksgiving."
