The “corruption rate” mapped below is calculated as the total number of public corruption convictions from 1997 to 2006 per 100,000 residents. The rates by state were compiled by Corporate Crime Reporter, based on Department of Justice statistics. Surprise: Illinois is not at the top; it’s pushed into the second tier by the Deep South. The ‘cleanest’ states, meanwhile, are in the West.

On The Monkey Cage, Prof. Sigelman first posted these data in tabular form, and Prof. Sides then followed up with a graph. That just left Prof. Gellman wishing for a map to better show the regional patterns. Well, this is my attempt at using the impressive-looking Many Eyes features to provide one. It’s a first attempt at using Many Eyes: I saw Nick Beaudrot use it to map out data before and I had to also give it a try.

The map may take a while to load, but is interactive: hover your mouse over a state and its corruption rate is shown. Clicking on a state highlights it; click on an unused area of the map to return to nationwide colour – and for some reason you may have to do this right at the beginning as well. On the version on the Many Eyes site itself, selecting a range of corruption rates in the legend highlights all states that fall within that range on the map.

Oddball observation of the day: at first glance I see a similarity between this map and the one showing where Obama did relatively best and worst, in comparison with the Democrats’ presidential score in 2004, among whites at least. Some parallel cultural elements at work?
