Manifesto Project Database


The Manifesto Project Database is the full database of political manifestos as well as election performance compiled by the Manifesto Research on Political Representation project, formerly known as the Manifesto Research Group/Comparative Manifestos Project. It is maintained on the website of the Social Science Research Center Berlin in Germany. It claims to be based on "quantitative content analyses of parties’ election programmes from more than 50 countries covering all free, democratic elections since 1945."

History

The Manifesto Project Database grew out of the work of the Manifesto Research Group/Comparative Manifestos Project, started before 2003. In 2003, Hans-Dieter Klingemann of Social Science Research Center Berlin received the American Political Science Association's Lijphart/Przeworski/Verba Data Set Award for the project.
Since October 2009, the Manifesto Project has been financed by a long-term funding grant from the Deutsche Forschungsgemeinschaft to the Manifesto Research on Political Representation project to update and make available manifesto texts and content-analytical data to the scientific community.
