Latest Versions of Data

To Uppsala University home page
This webpage offers access to the datasets and codebooks from the Uppsala Conflict Data Program (UCDP). For more specific information about the datasets, see the individual project pages. This webpage include links to the publications where UCDP publish updates annually on armed conflict data.

Those who are interested in detailed data for specific conflicts in the period 1989-2005 should consult the UCDP database , which offers a graphic user interface and extensive descriptive information.

The Armed Conflict dataset 1946-2005 is a yearly freeze of the conflict data in a format well suited for statistical analysis. Differences between the UCDP online database and this dataset can occur because the UCDP database is continously updated.
