ACLED data are collected and coded by a team of experienced researchers with specific language skills and country knowledge. Review processes oversee the collected data to ensure intra-coder reliability (i.e. that the researcher has coded everything in their country consistently). The data are further investigated and cross-checked by a regional research manager, who reviews inter-coder reliability across a region (i.e. that all researchers have coded information consistently across the region). Lastly, the data go through a final review from the global methodology team to ensure inter-code reliability, accuracy and methodological consistency (i.e. that all researchers across regions have coded everything consistently around the world).
In addition to weekly coding and review of the real-time conflict data, collection of historical data supplements the dataset. Comprehensive data management and quality assurance efforts performed on a regular basis ensures that the data reflect the latest and best information available. To that end, ACLED has an internal data quality assurance team.
