Led by Clionadh Raleigh
Jan 2004 – Sep 2014

ACLED (Armed Conflict Location and Event Dataset) is the most comprehensive public collection of political violence data for developing states. These data contain information on the specific dates and locations of political violence, the types of event, the groups involved, fatalities and changes in territorial control. Information is recorded on the battles, killings, riots, and recruitment activities of rebels, governments, militias, armed groups, protesters and civilians. Event data are derived from a variety of sources, mainly concentrating on reports from war zones, humanitarian agencies, and research publications.

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.
