This report is about gender norms – the implicit informal rules about appropriate behaviour for people of different genders – that most people accept and follow. It is about the ways in which gender equality, women’s and girls’ rights and the norms that shape the ability to claim those rights, have progressed over time. It examines how gender norms have changed in the 25 years since the UN’s Beijing Platform for Action on women’s rights was set out in 1995, and their role in progress and setbacks to achieving these rights.
