The correct answer is D. All of the above.
The Human Development Index (HDI) is a composite statistic of life expectancy, education, and per capita income indicators, which are used to rank countries into four tiers of human development. A country scores higher on the HDI if it has a higher life expectancy, higher education attainment, and higher per capita income.
Kerala has a high HDI score of 0.751, which is higher than the global average of 0.727. This is due to the state’s high performance in all three HDI components. Kerala has a life expectancy at birth of 75.9 years, which is higher than the global average of 72.6 years. The state also has a high mean years of schooling of 10.4 years, which is higher than the global average of 8.6 years. Finally, Kerala has a high GNI per capita of $6,230, which is higher than the global average of $10,966.
Kerala’s high HDI score is a reflection of the state’s commitment to human development. The state has invested heavily in education, healthcare, and social welfare, which has resulted in a high standard of living for its citizens.
