Climate Change and African Political Stability (CCAPS)
The CCAPS project, which is hosted by the Strauss Center for International Security and Law at UT-Austin, is devoted to the study of the relationship between climate change and international/internal stability on the African continent. The project has produced various data collections such as the Social Conflict Analysis Database (SCAD), which provides event-level data on riots, coups, strikes, and other instances of social unrest, and the Armed Conflict Location and Event Dataset (ACLED), which provides event-level data on various types of armed conflict.
Database of Political Institutions
This database was put together in part by Phillip Keefer at the World Bank and provides data on the political institutions and structures of different countries in the world from 1975 to 2012. The data are also available here, with coverage up through 2015. Please note the authors' preferred format for citing their data.
National Consortium for the Study of Terrorism and Responses to Terrorism (START) Data Collections
The National Consortium for the Study of Terrorism and Responses to Terrorism (START), which is funded in part by the Department of Homeland Security, is devoted to " utilizing state-of-the-art theories, methods, and data from the social and behavioral sciences to improve the understanding of the origins, dynamics, and social and psychological impacts of terrorism." As part of its work, it has assembled data collections on topics such as individual terrorist events, the organizational behavior of ethnic groups in the Middle East and North Africa, profiles of individual perpetrators of terrorist events in the United States, public opinion in Muslim-majority countries, and profiles of individual terrorist organizations. START's data collections are available via the START Terrorism Archive Dataverse.
Political Risk Services (PRS) Group Data
The Data Center's holdings include data resources from the PRS Group and other sources that measure "risk" in the form of political (in)stability and institutional quality (e.g. levels of corruption).
Quality of Government (QOG) Institute
The QOG Institute is hosted by members of the Department of Political Science at Göteborg University in Sweden and is devoted to "the causes, consequences and nature of 'good governance.'" The Institute has created four collections of data on governance: a broad collection of governance indicators that is global in coverage; a more narrow collection that focuses on social policy in wealthier countries; data from expert surveys on politicization and professionalization of public administration in individual countries, and a new data collection on perceptions of corruption in individual regions within EU members. The data are compiled from multiple sources, including the Polity Project, the Cingarelli-Richards Human Rights Data, Transparency International, Freedom House, various international organizations, and datasets produced by various academics. The QoG data are available in SPSS, Stata, and comma-delimited (.csv) formats.
