Data Resources for Political Science: Comparative Politics and International Relations

This is a compilation of commonly-used data resources for Political Scientists. The "Classic Rock" of Data, if you will.

Comparative Political Economy/International Political Economy

Eurostat
http://ec.europa.eu/eurostat/web/main/home
Eurostat is the statistical office of the European Union and collects a dizzying array statistical information on member states of the EU and other selected countries (e.g. non-EU OECD members, non-EU members in Eastern Europe). Much of their data are accessible on-line here and cover topics such as demographics, balances of payments, socio-economic indicators, and much data for sub-national regions within EU member states.

International Monetary Fund (IMF) Macroeconomic and Financial Data
http://data.imf.org/
The IMF's data library covers topics such as investment flows, monetary aggregates, economic output, commodity prices, exchange rates, public finances, financial institutions and markets, and both public and private debt. The available databases include the Balance of Payments Statistics, the Direction of Trade Statistics, the Government Finance Statistics, and the International Financial Statistics.

OECD iLibrary (Organization for Economic Cooperation and Development)
http://www.oecd-ilibrary.org/
The OECD iLibrary is an online interface that provides full-text access to OECD studies, periodicals, and dozens of statistical databases. The topical range of the iLibrary is considerable and covers areas such as agricultural policies, environmental indicators, social expenditures, labour markets, national accounts, foreign trade and FDI, and various industry-level data. While its focus is on wealthier developed countries, the iLibrary also includes OECD reports and publications on selected non-member countries such as the BRIC countries of Brazil, Russia, India, and China. This resource is also available via Databases at Emory.

United Nations Commodity Statistics Trade Database (Comtrade)
https://comtrade.un.org/
The UN's Comtrade database is a good source for commodity-specific bilateral trade data. Users can create their own extracts of data for both value and quantity of trade using different industrial classification codes and download those extracts for later use. Comtrade now also includes data on trade in services. This resource is also available via Databases at Emory.

UNCTAD Foreign Direct Investment Statistics
http://unctadstat.unctad.org
The United Nations Conference on Trade and Development (UNCTAD) maintains a database on FDI statistics, including flows, stocks, and participation in international investment-related agreements. It covers the years 1970 onward and allows users to download data into Microsoft Excel. UNCTAD's World Investment Reports are another useful source for FDI flows and stocks.

World Integrated Trade Solution (WITS)
http://wits.worldbank.org/WITS/
WITS is a joint undertaking of UNCTAD, the World Bank, and the World Trade Organization to integrate various databases on trade flows and trade restrictions.

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. corruption, accountability, bureaucratic quality). Our data from the PRS Group are monthly and cover the years 1984-2016.

Quality of Government (QOG) Institute
http://www.qog.pol.gu.se/
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.

Events Data

Climate Change and African Political Stability (CCAPS)
http://www.strausscenter.org/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 in Africa 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.

Computational Event Data System
http://eventdata.parusanalytics.com/index.html
The Computational Event Data System "uses automated coding of English-language news reports to generate political event data focusing on the Middle East, Balkans, and West Africa. These data are used in statistical early warning models to predict political change." The project's data collections consist of coded data on individual political events, including incidents of political violence. NOTE - events data files can be very large and often require some proficiency with database applications or statistical software.

National Consortium for the Study of Terrorism and Responses to Terrorism (START) Data Collections
http://www.start.umd.edu/data-and-tools/start-datasets
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 Global Terrorism Database is an especially commonly-used data source. START's data collections are available via the START Terrorism Archive Dataverse.
