ACLED (Armed Conflict Location and Events Dataset) (1997–)
ACLED is the most comprehensive public collection of political violence data for developing states, primarily in Africa and Asia. 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. All ACLED data can be downloaded on this site by country in excel and GIS formats.
