To measure gender differences in terms of wealth, health, and education, you would use the Gender Development Index (GDI). The GDI specifically accounts for gender disparities in these areas, making it a suitable choice for your objective.
The other options serve different purposes:
- Gross Domestic Product (GDP) measures overall economic activity but does not account for gender disparities.
- Consumer Price Index (CPI) tracks changes in the price level of a basket of consumer goods and services, not gender differences.
- GINI coefficient measures income inequality but does not specifically focus on gender differences.
