The original purpose of this project was to analyze existing data collections such as the PRIO battle death data and the Uppsala data on armed conflict to see whether they could be disaggregated according to gender and age as well as to causes of death. Our first finding was that there are practically no global data available that allowed us to investigate conflict mortality disaggregated by gender. When one looks further into this a number of methodological challenges to documenting conflict mortality more generally become evident, including distinguishing between direct and indirect conflict deaths, but we discuss these only briefly in the report. A part of the problem is that data exist on different levels. Very little information is available on a global scale, whereas good information can be found about the gender differences in smaller, intensively studied conflict areas.The research we have explored uses different datasets and investigates different conflicts and time periods, so it is difficult to say whether more men or women die overall from conflict. One general conclusion can however be drawn: men are more likely to die during conflicts, whereas women die more often of indirect causes after the conflict is over. Data on violent deaths [mostly survey data] confirm that men are more often victims of violence during wartime, whereas several studies that also take into consideration the post conflict period report a high number of female deaths after the conflict is officially over. It is still unclear what it is about these post conflict situations that leads to all these female deaths and this is a research area that merits more attention.
