Question 1

What is the Human Development Index (HDI) and how is it calculated?

Accepted Answer

The Human Development Index (HDI) is a composite index measuring average achievement in three basic dimensions of human development: health (life expectancy at birth), education (mean and expected years of schooling), and standard of living (GNI per capita PPP). It is calculated as the geometric mean of normalized indices for each dimension, ranging from 0 to 1.

Question 2

How does low human development drive migration in India?

Accepted Answer

Low HDI states like Bihar and Uttar Pradesh exhibit poor health, education, and income indicators, creating strong push factors — unemployment, agrarian distress, inadequate infrastructure — that drive large-scale out-migration to higher-HDI destinations like Maharashtra, Gujarat, and Delhi for livelihoods and services.

Question 3

What are the key differences between voluntary and forced migration?

Accepted Answer

Voluntary migration is driven by aspiration — better jobs, education, marriage, or lifestyle — while forced migration results from compulsion: conflict, natural disasters, development projects (dams, SEZs), or environmental degradation. The former reflects choice; the latter reflects survival necessity.
