evidence: Femicide is the murder of a woman because of their gender. We have reconstructed the incidence of femicide in Italy and Europe, notwithstanding the many difficulties in measuring the phenomenon. In Italy in 2022, women were the victims of 91 percent of homicides committed by family members, partners or former partners. [...] The European Institute for Gender Equality (Eige), the primary statistical reference for this subject, defines femicide as the murder of a woman because of her gender. This follows the definition provided by the UN Statistical Commission, and also adopted by Istat in Italy. [...] Gender-based violence and femicide is a complex and structural phenomenon that is particularly difficult to combat. There are minimal improvements over time, remaining almost unchanged compared to the parallel overall decline in violent acts and homicides in general, at least in the Western world. This is because it is a specific problem deeply rooted in patriarchal culture, which first and foremost requires an overturning of values. Education, inclusion of women in the workplace, better sharing of household duties: this is where prevention should start.
