While pathology deals with the individual body, epidemiology is concerned with the statistical measurement and spatial mapping of patterns of public health, disease, and mortality at the level of populations. With the advent of a general culture of crisis response and global health concerns, epidemiological and demographic studies of conflict-related mortality have begun to acquire a forensic dimension. Statistical data is increasingly called upon to play a role at the center of controversies involving international law and politics. The collection of epidemiological and demographical data by advocacy groups and aid organizations has thus become common practice. But recent debates around conflicts in Darfur, Sudan, the Democratic Republic of the Congo, and Iraq suggest that the more pronounced this quantitative turn has become, the more it is contested—and even lends itself to political and juridical manipulation.
