Step 1: Understanding the Concept:
The Gender Development Index (GDI) was introduced by the United Nations Development Programme (UNDP) to measure gender gaps in basic human development achievements.
Step 2: Detailed Explanation:
GDI is calculated as the ratio of the Human Development Index (HDI) calculated separately for females and males.
It evaluates achievements in three essential dimensions of human life:
1. Health (A): Measured by female and male life expectancy at birth.
2. Education (B): Measured by expected years of schooling for children and mean years of schooling for adults.
3. Economic Status (D) (Command over economic resources): Measured by estimated female and male earned income.
"Gender" (C) is the subject of comparison, not a direct dimension measured.
Thus, the correct dimensions are (A), (B), and (D).
Step 3: Final Answer:
GDI measures health, education, and economic status to quantify gender inequalities.
