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.

Project Description

Following the increase in demand from scholars of armed conflict to have access to reliable disaggregated data, the UCDP decided in February 2009 to convert all of its conflict- and dyad-level calendar-year data into a geo-referenced event data format.

The project’s first phase encompasses the conversion of annual data from the 1989-2010 time period in all three of the UCDP’s categories of organised violence: state-based armed conflict (1), non-state conflict (2) and one-sided violence (3). The dataset will, thereafter, be continuously updated annually.

The purpose of this project is to provide the academic community with the most comprehensive georeferenced event data available on organised violence in the post-1989 world, so as to answer the call for geographically and temporally disaggregated data. The data produced will be useable in both traditional statistical programs, as well as in GIS software.

The project’s end product is the UCDP Georeferenced Event Dataset (UCDP GED), a dataset which will be global, but also contain specific regional subsets. Several derivatives, such as conflict polygons will also be made available as they are produced within the project.

The first version of the UCDP GED, which contains a subset including the entirety of Africa, was released 8 December 2011. The first version of the dataset is in a point format, with the WGS84 datum for georeferencing. The first derivative dataset, the UCDP GED Conflict Polygons was released on 28 March 2012, with more derivative datasets to follow.

For more information and for downloading the dataset, please visit the UCDP GED dataset page.
