The correct answer is: a) Health, Education, Income.
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 if it performs better on these indicators.
The HDI was developed by the United Nations Development Programme (UNDP) in 1990 and is used to measure a country’s level of human development. The HDI is based on the following three dimensions:
- Health: Life expectancy at birth is a measure of the average number of years that a newborn is expected to live. It is a good indicator of the overall health of a population.
- Education: Mean years of schooling is a measure of the average number of years of schooling that a person has completed. It is a good indicator of the level of education in a country.
- Income: Gross national income per capita is a measure of the average income of a person in a country. It is a good indicator of the level of economic development in a country.
The HDI is calculated by taking the average of the three indices, with each index being given equal weight. The HDI is then ranked on a scale from 0 to 1, with 1 being the highest possible score.
The HDI is a useful tool for comparing the level of human development in different countries. It is also a useful tool for tracking progress over time. However, the HDI has some limitations. For example, it does not take into account inequality within a country.
