Chicago’s Disappearing Middle Class

President Obama has made a big deal recently about income inequality. The story in short is that the rich in the country are getting rich; the poor are getting poorer; and the people in the middle are fewer in number. Here in Chicago, this has meant that over the last few decades, many of the former middle-class neighbourhoods have been gutted of, well, the middle class. Daniel Kay Hertz has created a series of maps to show just how drastic the change has been since 1970.

Speeding on Chicago’s Tollways

The Illinois Tollways will be raising speed limits starting 1 January. Part of that process includes researching current driving habits and patterns. This graphic by the Chicago Tribune looks at some of the results. While the map part is necessary to show the routes themselves and the limits on those routes, the more interesting part is the dot plot below.

Rebuilding Chicago’s Red Line

For those of you who read this blog in Chicago know very well that the Red Line, Chicago’s busiest subway line, is undergoing major construction as the transit authority rebuilds much of the line. But what exactly does that entail?

Earlier this year the Chicago Tribune looked at that and with a series of illustrations, explained the different steps of the process. This first section details the steps taken to rip up the rails.

The Cost of Chicago’s Gun Violence

Today’s piece comes from Bloomberg and looks at the cost of Chicago’s gun violence epidemic. And when I write cost, I mean just that. While the lives lost are the most significant, Bloomberg’s article states that shootings cost Chicago $2.5 billion per year, or $2,500 per household. They supplemented their article with an infographic detailing and breaking down these costs by focusing on the South Shore in the city’s south side.

Historical Chicago Snowfall

Snow should fall upon Chicago this afternoon and it may measure up to a few inches in depth. But much of this winter has been below average. And that is much the same from last year when snowfall did not even reach 20 inches.

I went through NOAA data to look at the last decade of monthly snowfall to see just how little snow has fallen this winter. (Not a lot.) And then I looked at the entirety of the NOAA records to see where 2011/2 fit in the span of winters. (One of the least snowy.) This graphic is the result.

Whence Chicago’s Guns Came

Chicago has crime problems. Specifically homicides and gun-related crimes. This is despite the fact that Chicago has some of the strictest gun regulations in the country. But over the last decade, the Chicago Police Department has collected nearly 50,000 guns (excluding buybacks and turn-ins) of which nearly half originated from outside the state. The map below comes from an infographic by the New York Times that traces the origins of those guns.

Particularly useful are the small maps that accompany this larger one. The first looks at the Chicago metropolitan area, the second the country as a whole with counties filled-in if even one gun originated there, and then the third looks at Mississippi.
