Datasets

We are happy to welcome you to the Compendium Project dataset page. Essays of special relevance to data issues may be accessed directly from this page, and we have a listing of web datasets graciously provided by one of our authors, Paul Hensel, that will connect you to datasets of various sorts.

In the near future we also hope to provide a list of datasets in international studies that seeks to be comprehensive, and that will include materials not quite as complete, or directly related to international relations, as those in the Hensel list.

If you have any feedback or questions about this or any other element in our project please contact Compendium General Editor Bob Denemark

Notes:
The “Source” entry for each data set indicates the best place to obtain it. Where possible, this is the official site where the data set is maintained, which should always have the most up-to-date version. Also note that some data sets that are listed as being available by purchase only can be purchased by an entire institution through a site license; interested users may want to check with their school's library to see whether these resources are already available to them before paying the fee to access the data individually.

The “Typical Uses” entry for each data set indicates the most common uses for the data in recent years. Note that some data sets are very broad, and can be used for multiple purposes. Where relevant, data sets are listed under several different categories, as with data sets that are commonly used for studying both armed conflict and conflict management.

We have made every effort to make sure that this information is correct and complete at the time of publication, but there will inevitably be changes as data sets are moved to new hosts or new URLs. Do let us know if any corrections need to be made.

Prominent Replication Data Sets

These data sets are used frequently for replicating or extending previously published research. They offer the advantage of a ready-made set of dependent, independent, and control variables, allowing the user to change one or two elements of a published study to investigate a potential new relationship without having to collect and code the remaining variables.

Replication Data Archives

Many journals now require that replication data be made available upon publication of scholarly research. Some users host their replication data sets on their personal web sites, but many opt to use these official archives. The author of this chapter, Paul Hensel, also maintains his own International Relations Data Site with links to additional resources not included on this page.
