The UN Human Rights Office today published a report that, following rigorous assessment and statistical analysis of available data on civilian casualties, estimates that 306,887 civilians* were killed between 1 March 2011 and 31 March 2021 in Syria due to the conflict. This is the highest estimate yet of conflict-related civilian deaths in Syria.
The report, mandated by the UN Human Rights Council, referred to 143,350 civilian deaths that have been individually documented by various sources with detailed information, including at least their full name, date and location of death. In addition, statistical estimation techniques of imputation and multiple systems estimation were used to connect the dots where there were missing elements of information. Using these techniques, a further 163,537 civilian deaths were estimated to have occurred, bringing the total estimated civilian death toll to 306,887.
“The conflict-related casualty figures in this report are not simply a set of abstract numbers, but represent individual human beings. The impact of the killing of each of these 306,887 civilians would have had a profound, reverberating impact on the family and community to which they belonged,” UN High Commissioner for Human Rights Michelle Bachelet said.
