Significant public and media attention often follow the killing of women and girls outside of intimate or domestic relationships – or non-intimate partner and family-related (non-IPF) femicide/feminicide. However, less attention is paid to non-IPF femicide/feminicide in research and policy including an agreed definition.
What is currently known about these cases falls into a range of overlapping structural contexts, circumstances, and relationships, creating challenges for measurement. Non-IPF femicide/feminicide could include ‘stranger’ femicides or the killing of women and girls by acquaintances, employees, employers and clients. There is also the context of misogynist extremism, trafficking and organised crime, so-called ‘honour’ killings and more. Thus, a diverse range of relationships, contexts and circumstances emerge across non-IPF femicide/feminicides that require definition and synthesis.
A scoping review, Definitions of non-intimate partner and family-related femicide/feminicide: A scoping review, conducted by VISION researcher Dr Elizabeth Cook with colleagues Dr Caroline Miles and Merili Pullerits, identifies current definitions of non-IPF femicide/feminicide and the types of evidence that exist in relation to these killings.
The primary research question for the scoping review was: What definitions of non-intimate femicide exist and what types of evidence are available in relation to this type of femicide? The search strategy included electronic database searches (MEDLINE Complete, Social Policy and Practice, APA PsychInfo, Criminal Justice Abstracts with Full Text; Sociology Source Ultimate; Web of Science), citation-tracking, and hand searching non-governmental organisation websites (e.g., EIGE, UNODC, Femicide Watch). Sources were eligible for inclusion if they reported on women or girls aged 10 or above killed by non-intimate or non-domestic relations. Restrictions were not placed on study context, design or publication language. In total, 126 studies (140 reports) met the inclusion criteria.
The research shows that non-IPF femicide/feminicide encompasses a wide range of types (e.g., sexual femicides, work-related homicides) as well as relationships (e.g., strangers, acquaintances, clients, and employers). However, the team also found that a large proportion of studies did not substantively engage with the gendered contexts and motivations of killings.
Key findings
- Few reports define non-intimate partner or family-related femicide/feminicide
- Legal frameworks in Latin America and the Caribbean are key sources of definitions
- Reports noted specific risks for minoritised women (e.g., Black or migrant groups)
- Reports identified specific age groups at risk: adolescents and older age victims
- Definitions operate over three axes: space/location, intimacy, and circumstance
Recommendations
- Future research should provide clearly reported and explicit definitions of non-IPF femicide/feminicide including how ‘non-intimacy’ is qualified (e.g., emotional, physical, sexual, or other notions of trust, dependency, or care).
- Further research is required to unpack previously described ‘grey areas’ of intimate and non-intimate relationships (e.g., casual sexual partners, adolescent relationships, and dating relationships). This type of research would also provide opportunity to identified potential misclassification of femicide/feminicide.
- A significant number of quantitative reports were based on studies of sexual homicide which were focused on forensic characteristics of homicides and perpetrators behaviours and traits, rather than the structural circumstances in which these killings were committed. Future analysis should seek to foreground and interrogate the gendered social structures and relations that surround these femicides/feminicides.
- Further research is required that compares intimate and non-IPF-femicide/feminicide cases including victim, perpetrator, and incident characteristics, risk factors, and motives
- The availability of data on non-IPF femicide/feminicide is arguably lacking in comparison to data on intimate femicide/feminicide. The publication of various statistical classification frameworks is a promising development but requires application and testing in different jurisdictions.
- There is a specific need for intersectional analyses of non-IPF femicide/feminicide to understand how structures and histories of oppression create the conditions in which the killing of women is committed and rationalised (e.g., policing killings of Black women, or sexual femicides of migrant women).
