The Gender Inequality Index (GII) is a composite metric that reflects disparities between females and males in reproductive health, empowerment, and the labor market. It provides a measure of gender-based disadvantage across these three crucial dimensions of human development. The index ranges from 0 to 1, where 0 indicates perfect equality and 1 indicates complete inequality. For example, a country with high maternal mortality, low female representation in parliament, and a significant gap in labor force participation between men and women would likely have a higher score on the GII, indicating greater inequality.
This metric is valuable for understanding societal progress and identifying areas where policy interventions are needed to promote gender equality. It illuminates the multifaceted nature of gender-based disparities and their impact on overall human development. Historically, the development of such indices reflects a growing recognition of the importance of gender equality as a fundamental human right and a critical factor in achieving sustainable and equitable development. By quantifying these disparities, the index allows for cross-national comparisons and the tracking of progress over time, informing policy decisions and resource allocation strategies.
