Final answer:
The Human Development Index (HDI) includes life expectancy, educational attainment (including adult literacy and education enrollment)
Step-by-step explanation:
The Human Development Index (HDI) is a composite statistic used to measure a standard of human development in countries around the world. Two main components of the HDI are life expectancy, which reflects the ability to live a long and healthy life, and educational attainment, which includes adult literacy rates and enrollment in primary, secondary, and post-secondary education.
Another component is the standard of living, measured by purchasing-power-adjusted per capita real GDP. Together, these components provide a more comprehensive picture of a country's overall well-being, beyond just economic output., and the standard of living (GDP per capita adjusted for purchasing power) as its main components.
