About UCDP

The Uppsala Conflict Data Program (UCDP) has recorded ongoing violent conflicts since the 1970s. The data provided is one of the most accurate and well-used data-sources on global armed conflicts and its definition of armed conflict is becoming a standard in how conflicts are systematically defined and studied.

Replication Datasets

This webpage offers access to the datasets used by UCDP authors of articles appearing in academic publications. The data, and the ‘do’, ‘log’, ‘batch’, or ‘run’ file for the specific article are presented here together with additional information such as web-appendixes and dataset notes if applicable. The authors may also post the data on their own websites as well, and questions about the content of the dataset should be directed to them.

If you experience any problems accessing or downloading any of these datasets, please contact us at the following address: ucdp@pcr.uu.se
