Which indicator is used to measure the Knowledge' dimension of the Human Development Index?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1 i.e. Mean years of schooling and Expected years of schooling.
The HDI measures human development through three key dimensions: health, knowledge, and standard of living. For knowledge, the United Nations Development Programme (UNDP) uses two specific metrics:
-
Mean years of schooling: The average number of years of education received by people aged 25 and older.
-
Expected years of schooling: The total years of schooling a child of school-entrance age can expect to receive if prevailing patterns of enrollment rates stay the same throughout their life.
Other options like adult literacy or student-teacher ratios were either used previously or serve as secondary quality indicators, but they are not the current primary HDI metrics.
