The correct answer is: Standard of living, health, and education.
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. The index is used to measure a country’s level of human development and to track progress in improving the lives of its citizens.
The HDI is calculated using the following formula:
HDI = (Life expectancy at birth x 0.25) + (Mean years of schooling x 0.25) + (Gross national income per capita (PPP) x 0.25)
The HDI is a valuable tool for measuring human development, but it has some limitations. One limitation is that it does not take into account inequality within a country. Another limitation is that it does not measure non-economic aspects of human development, such as political freedom and social justice.
Despite its limitations, the HDI is a useful tool for measuring human development and for tracking progress in improving the lives of citizens.
