The aim of this website is to archive, maintain, and distribute datasets of roll-call voting from legislative bodies throughout the international community.
Data for the United States House of Representative and Senate (assembled by Keith Poole and Howard Rosenthal), from the European Parliament (assembled by Simon Hix, Abdul Noury, and Gerard Roland), from the United Nations (assembled by Erik Voeten), and many more legislative bodies are contained in this website. Vote World is a project of the Institutions and Governance Program at UC Berkeley, with the support of the EU Center of Excellence.

Researchers from all over the world are able to access this unique website to download data and also to upload their datasets and their papers. Active projects include the data on the United Nations General Assembly (assembled by Erik Voeten), the data on the Czech and Polish Parliaments (assembled by Noury and Roland), and the data on Latin American Parliaments (assembled by John Carey and his collaborators).
