A Collaborative Review of Evidence on Men and Boys in Social Change and Gender Equality. Designed to help answer the question, ‘what works best when it comes to engaging men and boys for gender equality?’, this evidence review critically assesses trends and shifts in related social norms and structures over the past 20 years, successful policies and programmes and implications for best practice, and future directions for promoting men’s and boys’ support for gender equality across a variety of priority thematic areas.
