The Fifth United Nations Survey, covering the years 1990-1994, was designed to collect data on the incidence of reported crime and the operation of criminal justice systems with a view to improving the dissemination of that information globally. To that end, the survey facilitates an overview of trends and interrelationships among various parts of the criminal justice system to promote informed decision-making in its administration, nationally and crossnationally.

A longitudinal national data series for 167 nations. The present dataset represents an expansion both of temporal coverage and of substantive variable categories from the earlier Cross Polity Time Series dataset (ICPSR 5002) by the Center for Comparative Political Research, State University of New York (Binghampton). General areas included among the 169 variables now available are demographic, social, political, and economic topics. The dataset consists of 8985 cases, which represent nation-year observations.

Information of domestic conflict for 111 countries were collected for the years 1919 - 1939 and 1946 - 1966. The variables record the occurrence of riots, demonstrations, and guerrilla war. Data exist for 42 years on 52 countries, and there are data for less than 42 years on 59 countries. Data may be obtained in either of two formats: nations as cases or nation/years as cases. In the first format a case would be Canada and variables would be riots-1919, riots-1920, riots-1921, etc.

What political scientists understand about African politics, they have gleaned largely from intimate knowledge of individual countries. While the case study method may illuminate a wealth of fascinating detail about political processes in particular settings, it cannot establish generalizations about continent- wide trends or test explanatory theories. Because of the paucity of systematic comparative analysis across African countries, analysts are hard put to make definitive statements about the nature and causes of contemporary political changes in Africa.

This dataset, a modified and updated version of POLITY II: POLITICAL STRUCTURES AND REGIME CHANGE, 1800-1986 (SN 2942)(ICPSR 9263), focuses on indicators of political authority and regime type for 177 members of the international system. Main Topics:

Main Topics:Please note: this study does not include information on named individuals and would therefore not be useful for personal family history research.

For each international system member, the number of missions received, the particular nations sending missions and the rank of mission from each nation are coded. Data are recorded at approximately five year intervals beginning in 1817. Main Topics:Please note: this study does not include information on named individuals and would therefore not be useful for personal family history research.

Carried out under the auspices of the Data Development for International Research (DDIR) project, Polity II was designed to develop longnitudinal indicators of political structures and regime change. This file encompasses most member states of the international system from 1800 to 1986 and consists of annual codings of regimes' structural characteristics, institutional changes, and the directionality of changes on underlying dimensions of democracy, autocracy, and power concentration.
