Content in the Yemen Data Project has been collected through open sources including: local and international news agencies and media reports, social media accounts (including Twitter, Facebook, YouTube and other video footage, and WhatsApp), reports from international and national NGOs, official records from local authorities, and reports by international human rights groups. According to the project where independent reporting is not available, the data has been cross referenced with sources from opposing sides to the conflict.
The data has been collected with the purpose of creating a statistical overview of the impact of the aerial bombardments in Yemen, especially in regard to geographical spread and its targeting. The data does not include casualty figures, neither combatants nor civilian, as in the current context of Yemen casualty monitoring presents significant challenges.
The first data collection project by the Yemen Data Project focuses on the aerial bombardments in Yemen from March 2015 to August 2016 and includes detailed data on all air raids conducted by the military coalition led by Saudi Arabia, which also includes participation from the United Arab Emirates, Egypt, Morocco, Jordan, Sudan, Kuwait, Qatar and Bahrain. The dataset lists the date of incident, geographical location, type of target, target category and sub-category, and, where known, time of day. Each incident indicates a stated number of air-raids, which in turn may comprise multiple airstrikes.
