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 high HDI score generally indicates a high standard of living, long life expectancy, and access to education and opportunities.
The HDI was developed by the United Nations Development Programme (UNDP) as a way to measure a country’s progress in terms of human development. The HDI is based on the following three indicators:
- Life expectancy at birth: This indicator measures the average number of years that a person is expected to live at birth. A high life expectancy indicates that people in a country are generally healthy and have access to quality healthcare.
- Education: This indicator measures the mean years of schooling and expected years of schooling for adults aged 25 and older. A high level of education indicates that people in a country have access to quality education and are able to develop their skills and talents.
- Per capita income: This indicator measures the gross national income (GNI) per capita, which is the total income of a country’s residents divided by the country’s population. A high per capita income indicates that people in a country have a high standard of living.
The HDI is a valuable tool for measuring human development and for tracking progress over time. It is also a useful tool for comparing countries and for identifying areas where there is room for improvement.
