1. Mapping Florida's Foreclosure Troubles

    The recent foreclosure crisis has resulted in significant economic and social strain throughout the United States. One place hit very hard during the recession is Florida.

The U.S. is second in CO2 production behind China.

Their website provides information on various topics and also includes access to graphics and free data. On the right side of their main page there is a list of datasets about communication systems by country for years 2000-2010. This is a very nice set of data because the data are time-series, and because the data appear to have few missing values. For this post I downloaded the dataset "Percentage of Individuals using the Internet".

    After the …
