Disaggregated Datasets

UCDP Georeferenced Event Dataset (GED) Global version 17.1 (2016)

This dataset is UCDP's most disaggregated dataset, covering individual events of organized violence (phenomena of lethal violence occurring at a given time and place). These events are sufficiently fine-grained to be geo-coded down to the level of individual villages, with temporal durations disaggregated to single, individudal days.

UCDP Actor List

Please do not cite this list; instead cite the dataset you used for your substantive analyses.

ID translation tables

In version 17.1 of all UCDP datasets, the ID system for conflicts, actors and dyads has been changed in order to make them unique across all UCDP core datasets and all UCDP types of violence. This will allow easier aggregation and disaggregation of data as well as simplify data management for users, especially when combining multiple UCDP products together.
This means all IDs used in this version of the dataset are no longer compatible with those in older versions of UCDP products. Further, this means that external products relying on UCDP IDs for data management tasks will have to be adapted to work with the new ID systems.
A conversion table between the new and old ID systems is available below, if you want to use the current datasets with the old ones

Other UCDP Datasets

UCDP Peace Agreement Dataset

The new Peace Agreement dataset, that covers peace agreements signed between at least two opposing primary warring parties in an armed conflict 1975-2011. The dataset is compatible with the UCDP Dyadic Dataset v. 1-2012, and UCDP/PRIO Armed Conflict Dataset v.4-2012. It has been constructed to allow researchers to analyze the different peace agreements. The unit of analysis is the peace agreement; consequently more than one agreement can be registered for one conflict- or dyad-year in the UCDP data. Each agreement is categorized as a comprehensive agreement, a partial agreement or a peace process agreement, depending on if the agreement is seen as a final product in a peace process or if the parties still have outstanding issues that have to be solved. Each agreement is also attributed with conflict, dyad and actor IDs from the other UCDP data to enhance the merging of different UCDP data collections.The UCDP Peace Agreement Dataset includes information on e.g. name, date, signatories and third parties of the agreement. Furthermore, it contains information on the provisions of the accords as well as different variables concerned with the termination of violence.

Full texts for most peace agreements are available here (or through links in the dataset).

UCDP External Support Dataset

A dataset providing information on the existence, type, and provider of external support for all warring parties (actors) coded as active in UCDP data, on an annual basis, between 1975 and 2009.


Choosing the right dataset:
The External Support – Primary Warring Party Dataset is best suited for analysis from the perspective of the receiver of support, as long as the analysis does not require the exclusion or inclusion of supporters, or the distinction of who supplied what.


The External Support – Disaggregated/Supporter Level Dataset is best suited for analysis from the perspective of the supporter, (e.g. analyses on number of supporters in a given year, actions of a particular supporter in a given region, etc.) or for more complex analyses (excluding some supporters, excluding some types of offered support etc.). The basic difference from the UCDP External Support – Primary Warring Party Dataset is that, if more than one supporter gave support to a party in a year, each individual supporter is listed on a separate row. As such, types of support need not be aggregated, each row containing the types of support that each external supporter gave to a certain receiver in a given year.

UCDP Managing Intrastate Low-intensity Conflict (MILC) dataset

An event-dataset that covers all measures taken by third parties in low-intensity intrastate dyad-years in the time period 1993-2004. The dataset includes information on e.g. the date of each event, name of third party/-ies, total number of third parties, type of measure, the topic of talks etc.

UCDP Managing Intrastate Conflict (MIC) dataset

A dataset containing all third party interventions in conflict dyads in Africa between 1993 and 2007. The dataset is highly disaggregated, the object of analysis being the dyad-third-party intervention event-day. For each third party intervention a substantial number of variables are collected. These include the identity and type (state, IGO, NGO etc.) of the interveners, the type and topic of intervention and the receiver of intervention (whether the target was the government, rebel(s) or both sides). Data is collected for all UCDP active years as well as for a three year period of inactivity after each conflict episode.
