The Institutions and Elections Project 

The Institutions and Elections Project (IAEP) at Binghamton University is a major data collection effort led by Professors Patrick Regan and David Clark. IAEP is a collection of data on political institutions and practices, and political elections for all countries in the international system between 1972 and 2005. The project is unique in its breadth of variables, ranging from legislatures to central banks, and in its breadth of countries, collecting such data on elections and institutions for both democratic and authoritarian states. The data were collected in two phases between October 2005 and September 2007. The data are identified by Correlates of War country codes and year, and thus are readily conformable with other state-year data sets (e.g. Polity). The data posted on this page are in Stata v. 9 format and in ASCII (comma delimited) format. The user's manual describing the data is in PDF and so requires Adobe's free reader. The notes files are unformatted text files for each country, containing discussions of coding decisions and sources. Please direct questions or comments to Patrick Regan or Dave Clark.

The research described in this data-collection project was sponsored by the Political Instability Task Force (PITF). The PITF is funded by the Central Intelligence Agency. The views expressed herein are the PIs' alone and do not represent the views of the US Government.
