Intranational Political Interactions

Intranational Political Interactions (IPI) Project

What’s Here?

This page briefly describes the Intranational Political Interactions (IPI) Project, contains links to the Codebook and Scales used, and the Cases and Actors for which we are collecting data.


The IPI project was co-directed by

  • David R. Davis, Associate Professor, Department of Political Science, Emory University
  • Will H. Moore, Associate Professor, Department of Political Science, The Florida State University

Brett Ashley Leeds (Assistant Professor, Department of Political Science, The Florida State University) served as the head Research Assistant while she was a Ph.D. student at Emory University. The IPI project was designed to measure political conflict and cooperation within societies through the coding of political event reports from international, regional, and local sources. These events were coded on two ten point scales which reflect the severity of various cooperative and conflictual statements and actions. This scaled events data can be used to calculate the volume and intensity of political conflict and cooperation within the domestic polity. In addition to facilitating the calculation of general levels of political conflict, the IPI coding scheme allows the examination of the dynamics of interaction among specific groups within the society. IPI gives scholars the ability to track interactions among social groups and between the state and social groups. The  National Science Foundation (SBR-9423762, SBR-9896144), the Institute on Global Conflict and Cooperation (University of California, San Diego), the Center for Social and Behavioral Sciences (University of California, Riverside), the Academic Senate of the University of California, Riverside, and the University Research Committee at Emory University have provided generous support for IPI.
