概要	The Gender Parity Index (GPI) is a simple, widely used indicator — standardised by the UNESCO Institute for Statistics — that expresses the value of an education statistic for females relative to males as a ratio. Most commonly applied to enrolment, completion, and literacy rates, a GPI of one signals parity, values below one indicate disparity favouring males, and values above one indicate disparity favouring females. It is the standard yardstick for monitoring gender parity in education, including in the Sustainable Development Goals.	The Gender Inequality Index (GII) is a composite measure introduced by the UNDP in the 2010 Human Development Report to capture the loss in potential human development due to inequality between women and men. It combines three dimensions — reproductive health, empowerment, and labour-market participation — into a single index ranging from 0 (perfect equality) to 1 (complete inequality), using an association-sensitive aggregation that penalises both gaps between the sexes and inequality across dimensions.
