Abstract: Carried out under the auspices of the Data Development for International Research (DDIR) project, POLITY II was designed to develop longitudinal 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.

SOURCE: Political characteristics were derived from a wide variety of historical and contemporary sources, including Banks, Arthur S. CROSS-NATIONAL TIME-SERIES DATA FILE. Binghamton, New York: Center for Comparative Political Research, State University of New York, 1986. Fiscal data were culled from the following sources: (1) Mitchell, B.R. EUROPEAN HISTORICAL STATISTICS, 1750-1970. New York: Columbia University Press, 1976. (2) Mitchell, B.R. INTERNATIONAL HISTORICAL STATISTICS: AFRICA AND ASIA. New York: New York University Press, 1982. (3) Mitchell, B.R. INTERNATIONAL HISTORICAL STATISTICS: THE AMERICAS AND AUSTRALASIA. Detroit: Gale Research Company, 1983.

UNIVERSE: Annual observations from 1800 to 1986 of 20 historical countries and 132 contemporary countries encompassing virtually all independent countries with populations of one million or more in the 1980s.
