Open States is a collection of tools that make it possible for citizens to track what is happening in their state's capitol by aggregating information from all 50 states, Washington, D.C., and Puerto Rico.
Using the site is simple: enter a U.S. address or select a state to start to research bills, review voting records, contact elected officials and more. Check out this Sunlight Academy tutorial to see how Open States can help citizens, journalists and activists learn more about their state government.
Additionally, collecting this data would not be possible without the support of a community much larger than the team here at Sunlight. A special thanks to all of our volunteer contributors and the authors and maintainers of all of the libraries that we depend upon.
Bill, legislator, committee and event data is collected from official sources, linked at the bottom of each legislator, bill, vote, committee or event page. For more details, visit our methodology page.
All told, the website and scrapers together comprise approximately 40,000 lines of Python, all of it open source.
We'd like to make special mention of a few projects that have made our life that much easier. This is far from a comprehensive list of the more than 40 projects that we rely upon throughout the project.
