Small Arms Survey
The Small Arms Survey is a global centre of excellence whose mandate is to generate evidence-based, impartial, and policy-relevant knowledge on all aspects of small arms and armed violence.
The MacroDataGuide was developed by the Norwegian Social Science Data Services to save researchers and students time and energy in their search for high quality social science macro data. While the main distinction is most often drawn between micro and macro data, the term 'meso data' is also sometimes used. Meso data generally refers to data on collective and cooperative actors such as commercial companies, organizations or political parties.
The Quality of Government Institute - QoG Datasets
The flagship datasest is the QoG Standard Dataset, which is available in both cross-section and time-series. The QoG Basic Dataset is easier to use, offering the most used and the most qualitative variables in terms of data from the QoG Standard Dataset. The QoG OECD covers countries who are members of the OECD. The EU Regional Data consists of approximately 450 variables from Eurostat and other sources. The QoG Expert Survey is a dataset based on our survey of experts on public administration around the world.

Cross National Time-Series (CNTS)
The Cross-National Time-Series Data Archive was launched by Arthur S. Banks in the fall of 1968 at the State University of New York at Binghamton. The archive was, in part, the outcome of an effort initiated some years earlier to assemble, in machine readable, longitudinal format, certain of the aggregate data resources of The Statesman's Yearbook, published since 1864. The archive has almost 200 variables and contains data for over 200 country units, with provision for entries from 1815 (excluding the two modern wartime periods, 1914-1918 and 1940-1945)

ProQuest International Datasets (IDATASETS)
Aggregates numeric datasets from international organizations, economic research firms, and national government statistical offices. This collection is designed to answer the three most common types of data questions in international research: How do two or more countries compare with one another across a range of statistical indicators? What are the social and demographic characteristics and trends in a single country? How do two or more internal regions of a country compare with one another across a range of indicators? A key provider of sub-national data (aside from the national governments themselves) is Oxford Economics.
