An interesting read from the Australian Institute of Criminology...
Homicide between
Intimate Partners in
Australia
Carlos Carcach and Marianne James
The National Homicide Monitoring Program database at the Australian
Institute of Criminology reveals that during the period 1 July 1989 to 30 June
1996, just over one-quarter of the 2024 homicide incidents, where the offender
was known, involved intimate partners. These include spouses, ex-spouses,
those in current or former de facto relationships, boyfriends, girlfriends, or
partners of same-sex relationships: in other words, all relationships where the
underlying dynamics are similar.
In almost 4 out of 5 intimate-partner homicides, the perpetrator was a
male and the victim a female. In a little over 1 in 5 incidents, the homicides
were committed by a female against a male. A small number corresponded to
killings among partners in same-sex relationships. One-third of intimatepartner
homicides resulted from conflicts associated with jealousy or the
termination of a relationship. The remaining incidents arose from domestic
arguments
