Indiana Superfund Locations vs Average Cancer Related Deaths

Screen Shot 2013-12-13 at 2.55.25 PM

The visualization above displays the state of Indiana broken into counties. Each county is shaded in order to display the number of deaths resulting from cancer. The darker blue the county is the more deaths on average have occurred. The overlying yellow circles are the locations that have been declared by the EPA as superfund sites.

The point of this project was to try and discover a correlation between superfund zones and the number of cancer occurrences within a given area. According to this map there does seem to be a higher number of cancer related deaths in the counties with more superfund sites. This may have something to do with higher cancer rates, but we cannot declare that it is the direct cause of cancer in these areas. There are numbers of other factors that could explain the cancer rates including anything from nutrition to poverty.

I went about creating this visualization by gathering data in order to display thebreakdown of number of cancer related deaths in each county. I gathered the superfund site locations from the EPA where I was able to find address and translate them to coordinates for the visualization. I also was able to use json data and sample code from a map on d3js that displayed unemployment by county in the United States.

Listed below is a link to the site where I have posted the visualization.

  1. This was a really awesome final project, especially since you seem to have found a correlation. I’m curious what this type of visualization would look like for each state. That’s fairly compelling evidence of the harmful effects of these sites, and I’m sure there is much more out there.
