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.

UCDP Datasets

About UCDP Data

The Uppsala Conflict Data Program (UCDP) offers a number of datasets on organised violence and peacemaking, all of which can be downloaded for free through the links below.

You can also generate your own dataset by using the tools "Dynamic Datasets" and "Customized Reports".

For datasets used by UCDP authors of articles appearing in academic publications, see Replication Datasets.

Those who are interested in detailed data for specific conflicts in the period 1975-2014 should consult the UCDP Conflict Encyclopedia (UCDP database), which offers a graphic user interface and extensive descriptive information. Differences between the UCDP online database and the datasets can occur because the UCDP Conflict Encyclopedia (UCDP database) is continuously updated.
