Methodology for civilian casualty data

Data for the civilian casualties from the air war were taken from the same sourcing as the Yemen Data Project's air raids data that has been collected contemporaneously since the start of the Saudi/UAE-led air campaign in 2015. It was then cross-referenced with other reporting from human rights organisations. The figures presented are the most conservative reported by open sources.

Identifying numbers

In cases where conflicting numbers are reported by open sources the lower number is used unless the incident has been verified by human rights organizations on the ground, in which case their number is used. If the number is identified but says women and children are amongst the casualties then 1 woman and 1 child is recorded, if the total is from 01 to 07. If the total is from 08 to 12, then 2 women and 2 children is recorded in the data. If sources use other terms such as 'tens killed' then 10 individuals are recorded. In the case of other unspecific terms such as 'hundreds killed including women and children' then 100 individuals are recorded including 20 women and 20 children; 'tens killed and injured' is recorded as 5 killed and 5 injured. The numbers produced are therefore the lowest numbers and likely an underreporting of the true figure.
