ICPSR has data (1946-1985) developed from the official records of the meetings of the main committees of the General Assembly of the United Nations. Data for the most recent sessions were primarily derived from the United States state department records of the United Nations roll calls. A major purpose of this data series was to provide for the analysis over time of world opinion on issues and concerns raised by members of the international community, while also allowing for the study of the dynamics through which alliances and factions are formed within and between nations of the world. The collection consists of roll calls voted upon in the United Nations. It is a composite of political debates and world opinions of the post-1945 international community. General Assembly Voting data through 2020 is available through Dataverse courtesy of Erik Voeten and Adis Merdzanovic.
