Catalist (http://catalist.us) maintains and constantly updates a complete national (50 States, plus the District of Columbia) database of over 280 million voting age persons (more than 185 million registered voters and 95 million unregistered adults). Serving the progressive community, Catalist brings powerful web based analytics tools and a high quality voter database of all voting-age individuals in the United States to progressive organizations and campaigns. In 2012, Catalist provided data services to more than a thousand progressive organizations to support membership recruitment, fundraising, legislative lobbying, voter registration, persuasion and mobilization, model building, online advertising, opinion surveys, program measurement, academic research, and social network organizing. Catalist data was also used in Virginia and New York this year.
