The problem of child homicide continues to be of major concern to researchers, policy makers and child welfare advocates everywhere. In particular, there is debate around the fundamental issues of defining and classifying such deaths. Here, a revised typology of child homicide is developed, by way of an update of the categories of fatal assault first delineated in Lawrence (2004). Taking into consideration significant advances in the field over the past decade, the typology is based primarily upon the developmental stages of the child, with the concept of homicide as the extreme manifestation of aggregate violence and maltreatment also central. The problem is further placed into the context of (1) child death research and review, it being argued that child homicide should ideally be studied as a sub-set of the entire cohort of child deaths for a particular jurisdiction, and (2) child maltreatment generally, in that wherever practicable child homicide research should consider fatalities in conjunction with other serious or near-fatal cases of abuse and neglect.
