This article presents findings from the International Men and Gender Equality Survey (IMAGES), one of the most comprehensive efforts of its kind to gather data on men’s attitudes and practices related to gender equality in eight low- and middle-income countries: Brazil, Chile, Mexico, India, Bosnia and Herzegovina, Croatia, Democratic Republic of Congo, and Rwanda. It provides a current picture of men’s attitudes about gender and gender equality, explores the determinants of equitable attitudes, and investigates the associations between equitable attitudes and relationship behaviors.
