In discussions of conflict, war and political violence, dead bodies count. Although the
politics and practices associated with the collection of violent-death data are seldom
subject to critical examination, they are crucial to how scholars and practitioners think
about how and why conflict and violence erupt. Knowledge about conflict deaths – the who,
what, where, when, why and how – is a form of expertise, created, disseminated and used by
different agents. This article highlights the ways in which body counts are deployed as
social facts and forms of knowledge that are used to shape and influence policies and
practices associated with armed conflict. It traces the way in which conflict-death data
emerged, and then examines critically some of the practices and assumptions of data
collection to shed light on how claims to expertise are enacted and on how the public
arena connects (or not) with scholarly conflict expertise.
