July 2018 update: For those interested in the raw point data (non-gridded) for the pre-ACLED period, 1980-1996, we have made the zipped .csv file available for download below. These data are coded in the ACLED style but are not maintained or included with their dataset. A word of caution: there are fewer events preceding 1997 due to the introduction of electronic data sources about that time. So if you are using this earlier dataset, be sure to control for this reporting bias by using another (non-conflict) data source.

Please cite our 2014 publication above if you use these data.
