Polity IV Data on Regime and Authority Characteristics
May 23, 2003
by University of Maryland Center for International Development and Conflict Management
This Web site contains information on and access to the most recent update of the well-known and highly respected Polity data series, originally designed by Ted Robert Gurr.
Polity IV contains coded annual information on regime and authority characteristics for all independent states (with greater than 500,000 total population) in the global state system and covers the years 1800-2000. This Web page contains a description of the Polity IV Project and provides access to the Registration page for downloading the dataset and users' manual; these materials are provided at no cost to consumers. It also contains hyperlinks to other Web-based depositories containing earlier versions of the Polity data series (i.e., Inter-University Consortium for Political and Social Research--ICPSR and the University of Colorado). The Polity IV Web site is housed at the Center for International Development and Conflict Management at the University of Maryland, College Park. This is the home site for the Polity IV Project and future updates of the data will be located here. Current plans call for semi-annual reviews and annual updates of the Polity data.
