The primary data used in this visualization comes from a dataset maintained by the Bureau of Investigative Journalism (BIJ) . The BIJ is a not-for-profit organization with the aim of educating the public and the media on both the realities of today's world and the value of honest reporting. While there were other data sources that had listings of drone stikes, the BIJ seemed to have the most unbiased collection of information.
Because the US Government does not disclose strike information, the data must be manually collected on the ground by reporters. The challenge is that stories and estimates vary between sources. In cases where there are inconsistencies, a minimum and a maximum number of possible fatalities are recorded. We take the average whole number between these estimates for each attack. In a few instances there were fatalities confirmed, but the estimated number of fatalities was not obtainable. In these cases, we simply omitted the fatalities.
The list of high-profile targets (the white squares) comes from the New America Foundation.
