About the Project
Voting America examines long-term patterns in presidential election politics in the United States from the 1840s to today as well as some patterns in recent congressional election politics. (Earlier congressional elections will be added in the future). The project offers a wide spectrum of animated and interactive visualizations of how Americans voted in elections over the past 168 years. You can also find expert analysis and commentary videos that discuss some of the most interesting and significant trends in American political history.
Voting America has been developed by the staff of the Digital Scholarship Lab at the University of Richmond. Andrew Torget, former director of the Digital Scholarship Lab, led the overall development of the initial version of Voting America that was launched in 2008. Nathaniel Ayers, the DSL's web designer, designed both the original and the revised versions of Voting America and developed the animated maps and interpretative videos. Scott Nesbit, now the DSL's associate director, Amanda Kleintop, a DSL research intern, and Edward L. Ayers, the president of the University of Richmond and a frequent DSL collaborator, all contributed to that version of Voting America. The current version of Voting America, launched in 2011, adds recent congressional elections and the 2008 presidential election and expands the visualizations beyond the continental US. Nesbit amassed and manipulated geospatial data. Nathaniel Ayers redeveloped the animations and redesigned the site. Robert K. Nelson, current director of the DSL, revised and rewrote some text on the site and wrote the code now used on the site. A number of student interns contributed to the production of usable datasets and geodata and to the production of the current version; those students are Megan Molnar, Stefan St. John, Holly McAleese, Taylor Hotchkiss, and Bridget Ward. Edward L. Ayers continues to serve as consulting editor on the project.
The political data that underlies Voting America was collected from four sources:
- Datasets for presidential elections from 1840 through 1972 came from the Interuniversity Consortium for Political and Social Research study #8611: "Electoral Data for Counties in the United States: Presidential and Congressional Races, 1840-1972," by Jerome M. Clubb, William H. Flanigan, and Nancy H. Zingale.
- Datasets for the presidential election from 1976 through 2004 was licensed from Polidata.
- Data for the 2008 presidential election came from the U.S. Geological Survey using data supplied by State elections authorities. 2008 state elections results come courtesy of the Federal Elections Commission.
- Datasets for congressional election data came from the Office of the Clerk, U.S. House of Representatives
The GIS shapefiles for county boundaries in the United States came from the National Historical GIS project (NHGIS) at the University of Minnesota. Congressional boundaries for the 106th through the 111th Congress come courtesy of the National Atlas of the United States. Congressional boundary files for the 103, 104, and 105th congresses come from the U.S. Census bureau, Geography division. Population data was also collected from NHGIS and has been aggregated by decade corresponding to the U.S. census.
The animated maps were created using the ArcGIS suite of digital cartography tools to map the raw political data in space and time. A variety of visualizations of these dataset were generated in and then exported from ArcGIS. The exported maps were then combined into animated timeseries using Adobe AfterEffects to create the animated maps. The interactive application developed by GroundWorkDesign uses Adobe Flash and Flex.
