This chapter aims to take a first step towards that goal. Though constrained by issues of data availability, we build on the ideas of the various gender indices available to choose variables that capture various aspects of gender inequality over time. This chapter provides an overview of gender inequalities in various dimensions of well-being, following the conceptual framework of How Is Life? ( Furthermore, discrimination can take place throughout a woman’s life cycle, from birth (resulting from sex-selective abortions, such as in the case of China) to access to education (for instance in school enrolment rates) and continuing through the rest of their life course (e.g. labour force participation and life expectancy) (OECD, 2013).
