Elections produce a huge amount of data, from the number of registered voters to how many of those voters turn out to cast their ballots. Much of this data is of interest for research, but it can be difficult to navigate or even locate at all; each state has its own policies and practices that govern what data it makes available, how, and to whom.
For 2026, we are producing data guides that steer researchers through what data are available and where to find it for 11 states: Texas, North Carolina, Georgia, California, Arizona, Michigan, Wisconsin, Minnesota, Nevada, New York, and Pennsylvania. As with the state reports, data guides will be available after these states' primaries, as they certify and share reporting numbers.
Find our published state data guides below, or linked on each state's update page:
Nevada publishes statewide election data through the Secretary of State's Elections Division; these data include official results back to 1962, precinct-level results and cast vote records for recent elections, monthly voter-registration snapshots, and the statewide voter file.

Wisconsin has the most decentralized election administration in the country: elections are conducted by roughly 1,850 municipal clerks, canvassed by 72 county clerks, and certified by the Wisconsin Elections Commission (WEC), which also maintains the statewide voter registration system.
