There are 14 years of data, starting in 2000, but the first two appear to be incomplete and of course 2013 isn’t over yet, so I restricted my analysis to 2002-2013. I wanted to map the data, not because I had any interesting point to make about the location of federal contracts, but rather because I wanted to get more practice using Kartograph. Unfortunately, the raw data does not provide very good information on the locations of contract winners. Most of the time there is a little bit of location data embedded in a field for the contract winner’s name. But these are often nothing more than zip codes or incomplete addresses. To locate the data on a map, these addresses needed to be geocoded (turning an address into a lat/lon coordinate pair).
