ACLED (Armed Conflict Location and Event Dataset) is designed for disaggregated conflict analysis and crisis mapping. This dataset codes the dates and locations of all reported political violence events in over 50 developing countries. Political violence includes events that occur within civil wars or periods of instability. Although civil war occurrence is decreasing across African countries, new forms of political violence are becoming more common.
ACLED is directed by Prof. Clionadh Raleigh (Trinity College Dublin). It is operated by senior research manager Caitriona Dowd (Trinity College Dublin). Andrew Linke is a consultant on the project (University of Colorado) while the data collection is led by research analysts Annie Ngwira and Charles Vannice.
ACLED tracks these movements to present a dynamic and comprehensive assessment of political violence in developing states.
These data contain information on:
- Dates and locations of conflict events,
- Specific types of events including battles, civilian killings, riots, protests and recruitment activities
- Events by a range of actors, including rebels, governments, militias, armed groups, protesters and civilians;
- Changes in territorial control
Event data are derived from a variety of sources including reports from developing countries and local media, humanitarian agencies, and research publications. Please review the codebook and user guide for additional information: the codebook is for coders and users of ACLED, whereas the brief guide for users reviews important information for downloading, reviewing and using ACLED data.
ACLED is associated with the International Peace Research Institute and has received funding from the World Bank, the Climate Change and African Political Stability (CCAPS) Minerva project and the European Research Council.
Data are available for public download from the data page. Data for all African countries are from January 1997 to December 2012. Real-time monthly ACLED data for select African countries is available for viewing at CCAPS and can be downloaded as real-time updates. For non-African states, data is available from 1997-2010, with shorter time periods of Afghanistan and Pakistan, which are both covered from 2006-2009.
Maps and trend analyses of ACLED data are available. On the Maps/Graphs page, dynamic data mapping for users is made available through SpatialKey and dynamic graphs through Tableau. The static maps and graph section contains visual reviews of the updated data. Trend analysis for the African continent and individual states is found on the Trends page. Trend reports which review monthly changes and patterns of political violence is available on the Publications page.
