The Gender Gap Report, published by the World Economic Forum (WEF), assesses gender disparities in various areas and ranks countries based on their progress towards gender equality. The report measures gender gaps across four key areas, which are mentioned above.

1. Economic participation and opportunity:

It includes factors such as wage equality, labor force participation, and representation in leadership roles. The Gender Gap Report evaluates the gender gap in these areas and ranks countries accordingly.

2. Educational attainment:
This marker examines gender disparities in education, including access to primary, secondary, and tertiary education. It measures the literacy rate, enrollment rates, and gender parity in education. The report highlights the progress made by countries in closing the gender gap in education.

3. Health and survival:
This marker focuses on gender disparities in health outcomes and life expectancy. It considers factors such as mortality rate, access to healthcare, and reproductive health. The Gender Gap Report assesses the gender gap in health and survival and ranks countries based on their performance in this area.

4. Political empowerment:
This marker evaluates the representation of women in political leadership roles and decision-making positions. It considers factors such as the number of women in parliament, ministerial positions, and heads of state. The report assesses the gender gap in political empowerment and ranks countries based on their progress.

In summary, the Gender Gap Report, 2023, assesses gender disparities in economic participation and opportunity, educational attainment, health and survival, and political empowerment. These key markers provide a comprehensive analysis of gender inequality and help in identifying areas where progress is needed.
