A higher HDI indicates:

Better overall development
Higher income levels only
Better health outcomes only
Improved education levels only

A higher Human Development Index (HDI) indicates better overall development. The 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 higher HDI indicates a better standard of living and a higher quality of life for citizens of a country.

The HDI was developed by the United Nations Development Programme (UNDP) in 1990. It is used to measure a country’s level of development and to track progress over time. The HDI is calculated using three indicators: life expectancy at birth, mean years of schooling, and expected years of schooling, and gross national income per capita.

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 development, such as environmental sustainability or social inclusion.

Despite its limitations, the HDI is a useful tool for measuring human development and for tracking progress over time. It is important to remember that the HDI is just one measure of development, and that it should not be used in isolation.
