This contribution for Political Insight (June 2019, Volume 10, Issue 2) maps gender inequality around the world and argues that the political sphere is often the most resistant to change. Unequal treatment based on gender is deeply embedded in many countries. Gender studies emerged as an important part of academic research in the 1980s. The issue of gender inequality also emerged on the global political agenda, albeit slowly. Gender-related measures became part of the Human Development Index (HDI) by the United Nations Development Programme (UNDP).
