- "data include election returns, socioeconomic summaries, and demographic measures of the American public at unusually low levels of geographic aggregation."
- "The NSF-supported ROAD project covers every state in the country from 1984 through 1990 (including some off-year elections).
- One collection of data sets includes every election at and above State House, along with party registration and other variables, in each state for the roughly 170,000 precincts nationwide (about 60 times the number of counties).
- Another collection has added to these (roughly 30-40) political variables an additional 3,725 variables merged from the 1990 U.S. Census for 47,327 aggregate units (about 15 times the number of counties) about the size one or more cities or towns.
- These units completely tile the U.S. landmass. This collection also includes geographic boundary files so users can easily draw maps with these data."
"The study of urban and local politics in the United States has long been hindered by a lack of centralized sources of election data. We introduce a new dataset of about 78,000 candidates in 57,000 electoral contests that encompasses races for seven distinct local political offices in most medium and large cities and counties in the U.S. over the last three decades. This is the most comprehensive publicly-available source of information on local elections across the country. We provide partisan and demographic information about candidates in these races as well as electoral outcomes. This new dataset will facilitate a myriad of new research on representation and elections in local governments."
