And We’re Back

Despite the lack of activity on this blog, the Chicago Crime Project has been ongoing.  Specifically, I have continued to collect dataand have been improving the method of interpreting the data.  As you may have noticed, the data we were dealing with before was all aggregate (i.e the total amount of various crimes in various areas), which is fine as far as it goes (and when we only had six months of data).  Now, however, I have two years of data and the time is here to start doing fund and informative things with time series.  There will be day to day charts on all manner of issues as we move forward.  First, however, is an update of the famous violent crime and property crime maps.  They are not only more readable and visually pleasing than the old ones, but I have abandoned the relative ranking I used to do (i.e. the 10 best neighborhoods are one color, the next 10 best another, and so on) and have adopted absolute ranking (i.e. neighborhoods below x crimes per capita are one color, neighborhoods above x but below 2x crimes per capita are another, and so forth).  This, I believe, will give a more accurate picture of crime in the city.  Note that violent crime has a more fine-grained spectrum than property crime.  This is because, for better or worse, there is a much richer and varying fabric of violent crime than property crime in this city.  I have also tweaked slightly the formula I use to calculate the Violent Crime Index.  More on this later.  Now, the maps:

    What is the range of crimes per capita for each category. To me Logan Square feels different than Uptown.
