The Human Development Index (HDI) is a statistical tool used to measure a country's development based on three dimensions:

  1. Life Expectancy (LE): measured by the average number of years a person can expect to live.
  2. Education (ED): measured by the expected years of schooling and the gross enrollment ratio in education.
  3. Gross National Income (GNI) per capita (GNI): measured by the total income of a country's citizens, adjusted for purchasing power parity (PPP).

The HDI is a composite index that ranges from 0 to 1, with higher values indicating better human development. The index is calculated by combining the three dimensions using the following formula:

HDI = (LE + ED + GNI) / 3

Here are the HDI values for some countries:

High Human Development (HDI ≥ 0.8):

Medium Human Development (HDI = 0.5-0.799):

Low Human Development (HDI < 0.5):

The HDI is a useful tool for comparing the development levels of different countries and identifying areas where improvements can be made.
