Precinct-Level Election Data Project |
|
With financial support from the Sloan Foundation, I am collaborating with Stephen Ansolabehere at Harvard University on a large data collection endeavor.
We are collecting precinct-level results for as many U.S. elections as possible since 2000, and then linking these results to GIS boundary files of voting tabulation districts. These VTDs can easily be linked to 2000 and 2010 census blocks.
Our geo-referenced election data are being fed into newly-developed online redistricting software, which can be used as part of a more open, transparent redistricting process. To draw your own electoral districts and calculate various statistics of interest, please visit one of the following:

The data are being archived and released at: http://projects.iq.harvard.edu/eda/data
We intend to complete close to 50 states by the end of summer 2011. We expect to update the page frequently.
We will also create an interactive online visualization tool. Please check this page for updates.
In the longer term, we intend to expand our data release and visualization tool to include geo-referenced polling-place or precinct-level data from several additional countries. Suggestions about data sources are welcome.
Throughout the 2012 redistricting season, I will update this page with maps and occasional analysis.
Here are some initial maps that may be of interest (click for larger size): |
