ACLED (Armed Conflict Location and Event Data Project) is designed for disaggregated conflict analysis and crisis mapping. This dataset codes the dates and locations of all reported political violence events in over 60 developing countries in Africa and Asia. Political violence includes events that occur within civil wars and periods of instability, public protest and regime breakdown. The project covers all African countries from 1997 to the present, and South and South-East Asia in real-time.
ACLED is directed by Prof. Clionadh Raleigh (University of Sussex). It is operated by senior research manager Caitriona Dowd (University of Sussex) for Africa and Sarah Kaiser-Cross for South and South-East Asia. The data collection involves several research analysts, including Hilary Tanoff, Charles Vannice, James Moody, Daniel Wigmore-Shepherd, Andrea Carboni, Matt Baden-Carew, Roudabeh Kishi, Fatima Zeb and others.
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; and
- Reported fatalities.
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. A specific user guide for development and humanitarian practitioners is also available, as is a guide to our sourcing materials.
Data are available for public download from the data page. Data for all African countries are from January 1997 and are updated in real-time. Data for South and Southeast Asian countries are produced between 2010-2015 for the first stage of release. Real-time monthly ACLED data for South and Southeast Asian and African countries is available for download on this or the Climate Change and African Political Stability Project (CCAPS) website. For more information, please contact Prof. Raleigh or the project administrator using the contact form on this website. Other data coded in the initial stage of this project are available from the data page, under various version headings.
Maps and trend analyses of ACLED data are available in several locations and forms: real-time analysis of conflicts can be found on the ACLED Crisis Blog; trend reports which review monthly changes and patterns of political violence and are available on the Publications page; maps and graphics of real-time violence are available on the Visuals page; and in-depth research papers can be found on the Research page.
