Constituting the fifth part of the Global Study on Homicide 2019, this booklet gives an overview of the scope of gender-related killing of women and girls. It provides in-depth analysis of killings perpetrated within the family sphere and examines forms of gender-related killings perpetrated outside the family sphere, such as the killing of women in conflict and the killing of female sex workers. The booklet explores the scale of intimate partner/family-related killings of women and girls, and describes different forms of gender-related killings of women. It also looks at the characteristics of the perpetrators of intimate partner killings, the link between lethal and non-lethal violence against women, and the criminal justice response.
