“Counting Feminicide” documents and supports the work of grassroots feminist data activists as they engage in documenting feminicides and gender-related killings, particularly across the Americas. The book explores the intersection of data science and social activism, revealing the power of restorative and transformative data science to bring about social justice and challenge mainstream forms of data science. Catherine adopts an intersectional approach to address how feminicides are linked to racism, colonialism, and economic injustice. It also highlights the specific challenges faced by Indigenous and Black women, who often lead the fight against feminicide. The book underscores the need to understand feminicide within these broader systemic contexts to effectively address and prevent it, aiming for a world where gender-related killings are eradicated because the political and economic conditions that produce such violence no longer exist.
