For example, as highlighted in Chapter 2, the gender pay gap often increases once education is accounted for. Context specific factors - not only women and men's varying levels of education, but also related to types of employment, hours worked, and institutional and policy environments - can also make cross-country comparisons of the unadjusted pay gap difficult. Household surveys usually include questions for women about decision-making at the household level, which provide valuable insights into women's voice and agency in their daily lives. Women's political participation, however, is currently measured using the percentage of women in national parliaments, which does not reveal anything about the impact of women's representation on policy or about women's decision-making in other spaces, including in local governments or civil society organizations.
