A few years ago, Azavea created a product, Cicero that enables organizations to rapidly match addresses to local, state and national legislative districts, find contact information for elected officials and create maps of districts. The software is used for advocacy, political action, reporting and many other purposes. The system is based on geographic data, so Azavea spent a lot of time tracking down legislative boundaries for locations all over the United States and then, later, other parts of the world.

One of the things Azavea observed was that the home of their main office, Philadelphia, had what appeared to be some of the craziest council districts in the country. They wondered just how crazy they really were. So they started doing some research on metrics for assessing the degree to which a given district might be gerrymandered. This led to their first Gerrymandering Index White Paper in fall of 2006, in which they assessed both Congressional and local districts. It was well received both locally and nationally and contributed to a conversation in Philadelphia about how both the districts and the system might be changed.

In 2010, Azavea's Cicero product was extended to include more cities, state legislatures and other countries, so they decided to take another crack at the white paper, this time in the context of the 2010 Census and 2011 redistricting process.

With the latest round of Congressional redistricting now complete, Azavea set out to measure districts compactness again and assess how the results from this latest round of redistricting has affected the geometry and geography of legislative districts in the United States. The results are in our newest white paper "Redrawing the Map on Redistricting 2012 - Addendum".
