Disaggregated Datasets
UCDP Georeferenced Event Dataset (GED) Global version 24.1
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, individual days.

UCDP Peacemakers at Risk (PAR) Dataset version 1.0-2016
This event-dataset tracks violence against peacekeepers deployed to conflict-affected countries in sub-Saharan Africa as part of both UN and non-UN peace operations. The Peacemakers at Risk (PAR) records reported incidences of violence resulting in direct peacekeeping personnel fatalities, injuries and kidnappings. Each recorded event also provides information on the timing, location and actors implicated, as well as on the nationalities of those violence-affected peacekeepers. The dataset also tracks reports of fatal violence perpetrated by peacekeepers, which allows for the study of peacekeepers' use of force. In its current version, the dataset covers the 1989 - 2009 time-period. The dataset is made compatible with other existing UCDP datasets on organized violence.

UCDP Violent Political Protest Dataset version 20.1
A dyad-year dataset identifying violent political protests, 1989-2019. It presents a new –standalone- category of organized violence, which complements, and is compatible with, UCDP’s three categories of organized violence: one-sided violence, non-state, and state-based conflict.

Cities and Armed Conflict Events (CACE)
The Cities and Armed Conflict Events (CACE) dataset constitutes an extension of the UCDP-GED. CACE provides a systematic coding of whether these armed conflict events took place in cities. To identify which events of armed conflict took place in cities, the data was manually matched to data from the United Nations Statistics Division (see the codebook for more details). The current version is based on UCDP-GED v 18.1.

ID translation tables
In version 17.1 of all UCDP datasets, the ID system for conflicts, actors and dyads was changed in order to make them unique across all UCDP core datasets and all UCDP types of violence. This allows 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 the dataset from version 17.1 and onwards 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.

UCDP Conflict Termination Dataset version 3-2021
This dataset provides information on specific start- and end- dates for conflict activity and means of termination for each conflict episode. The data is available as a conflict-level dataset which corresponds with the UCDP/PRIO Armed Conflict Dataset v 21.1, and a dyad-level dataset which corresponds with the UCDP Dyadic Dataset v. 21.1.

UCDP Non-state Conflict Issues and Actors Dataset
A dyad-year dataset containing information on conflict issues and key actor characteristics in non-state conflict. The dataset covers non-state conflicts in Africa, 1989-2011 and is compatible with the UCDP Non-State Conflict Dataset v. 2.5-2016.
The data builds on and extends the UCDP Non-State Conflict Dataset by introducing additional information on what the actors in the conflict are fighting over, alongside actor characteristics. The data set distinguishes between two main categories of issues, territory or authority, in addition to a residual category of other issues.

The data builds on and extends the UCDP External Support Dataset and the UCDP Non-State Conflict Dataset by introducing additional information on external support to warring parties in non-state conflicts.

UCDP External Support Dataset (ESD)
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 2017. The ESD builds on the UCDP Dyadic Dataset 18.1 derived from the UCDP/PRIO Armed Conflict Dataset 18.1 but goes beyond the dyad-level and offers the warring party-opponent-year (actor-year) as well as the warring-party-supporter-opponent-year (or triad-year) as units of analysis in addition to the dyad-year.
Choosing the right dataset:
When using the ESD, researchers can choose between the following three different units of analysis: the triad-year version (ESD TY), the actor-year version (ESD AY), and the dyad-year version (ESD DY). Further units of analysis, e.g. at the conflict-level or the actor-level, can be created from the triad-year version.
ESD TY: Triad-year The triad-level dataset (ESD TY) is the most disaggregated and extensive version of the data. It contains yearly information on the external supporter and the recipient of support specific to the conflict-dyad the recipient is involved in. It thus contains one observation (row) for each combination of external supporter, recipient, and opponent per year. All aggregated versions of the dataset can be built from this version. This version is appropriate where the focus rests on the individual external supporters and can be used to create aggregate measures of characteristics of the external supporter such as, e.g. combined military capabilities.
ESD AY: Actor-year The actor-year dataset (ESD AY) contains all support a recipient receives in a given dyad-year. If more than one external supporter provides external support, the external support is combined and presented as aggregate measures. It thus contains one observation (row) for each actor per dyad-year. This version is appropriate where the focus rests on the recipients of external support regardless of which external supporters provide the support.
ESD DY: Dyad-year The dyad-level dataset (ESD DY) is the most aggregated version of the three datasets and presents information on external support to the conflict-dyad as a whole at the dyad-year unit of analysis. If more than one external supporter provides external support, the external support is combined and presented as aggregate measures. As such it contains one observation (row) for each dyad per year. This version is appropriate where existing data is in a dyad-year structure or the focus rests on the impact of external support on conflict more generally.

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 compatible with the UCDP Dyadic Dataset v.1 2010 for the years 1993-2007. 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.
