This book presents a multidimensional, psychosocial and critical understanding of poverty by bringing together studies carried out with groups in different contexts and situations of deprivation in Brazil, Mexico, Paraguay, Nicaragua and Spain. The book is divided in two parts. The first part presents studies that unveil the psychosocial implications of poverty by revealing the processes of domination based on the stigmatization and criminalization of poor people, which contribute to maintain realities of social inequality. The second part presents studies focused on strategies to fight poverty and forms of resistance developed by individuals who are in situations of marginalization.
