The Correlates of War 2 International Governmental Organizations Data Version 2.0

Pevehouse, Jon, Nordstrom, Timothy, Warnke, Kevin·2004·Conflict Management and Peace Science

Abstract

This article summarizes the new Correlates of War 2 International Governmental Organizations (IGOs) data. The data in the Correlates of War IGO data sets capture state memberships in the network of international governmental organizations. The expanded version 2.0 updates the original Wallace and Singer (1970) data set to provide membership information from1964 to 2001. Following a brief review of the literature pertaining to IGOs and world politics, we provide descriptions of all three versions of the data (country-year, IGO-year, and joint dyadic membership), discuss coding rules and subsequent changes to the data, and present graphical representations of changes in the network of IGOs over time using all three versions of the data.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
