Dimensionality of Nations Project: Nation Attribute Data, 1950-1965 (ICPSR 5020)

Principal Investigator(s): Rummel, Rudolph J.


This study contains data on the political, economic, religious, ecological, and demographic characteristics of 113 nations in the years 1950, 1955, 1960, 1963, and 1965. Originally collected by the Dimensionality of Nations (DON) Project at the University of Hawaii, these data provide information on political regime characteristics, such as the number of political parties, electoral system, political leadership, the nature of the political system, horizontal power distribution, communist party membership, the legitimacy of present government, the legality of government change, freedom of opposition, major government crises, bureaucracy, and the occurrence of assassinations, riots, general strikes, protests, domestic violence, demonstrations, threats and accusations, and purges. Economic variables focus on gross national product (GNP), aid received from the United States and Russia, national income, government expenditures, government balance of payment, investments, imports and exports, energy production and consumption, agricultural production, and the economically active population. Demographic variables include age, education, literacy, religion, ethnicity, marital status, immigrants, and migrants. Other variables provide information on the nations' bloc memberships, United Nations' assessment of the nations, air distance of the nations from the United States, number of nongovernmental organizations, number of the nations' diplomats expelled or recalled, age of the nations, and the nations' geography.
