Final answer:
The Gender Development Index (GDI) measures gender inequality within a nation, while analyzing HDI standings among SAARC nations helps assess the level of development and standard of living in each country.
Step-by-step explanation:
The Gender Development Index (GDI) is an important measure used to assess the gender inequality within a nation. It adjusts the variables used in the Human Development Index (HDI) to account for gender disparities, such as differences in education and life expectancy between males and females. By measuring GDI, we can identify countries where there is a greater disparity in achievement between males and females, highlighting the need for gender equality.
When analyzing the standings of HDI among SAARC nations, we can compare the HDI rankings of these countries and assess the level of development and standard of living in each nation. This allows us to understand the variation in human development across the region and identify areas where improvements are needed.
