The paper “COVID-19 from the Margins. Pandemic Invisibilities, Policies and Resistance in the Datafied Society” examines the impact of the pandemic from a perspective focused on marginalized and underserved communities. It focuses on how technology and data collection have affected groups such as informal workers, victims of domestic violence, and low-income families, who have been overlooked in the mainstream narrative. The book explores issues such as the invisibility of these communities, perpetuated inequalities and data-driven social policies, as well as technological reconfigurations in the context of the pandemic. It also highlights the importance of grassroots, technology-driven solidarity and resilience in times of crisis.
