Click any country to see its Human Development Index — a 0-to-1 score combining health, education and income.

Key facts
- The highest-scoring countries are above 0.95; the lowest below 0.40.
- HDI combines life expectancy, schooling and income per person.
- It was designed as an alternative to judging development by GDP alone.
Common questions
What is the Human Development Index?
A summary measure of average achievement in three dimensions — a long and healthy life, knowledge, and a decent standard of living — expressed as a score between 0 and 1.
Why use it instead of GDP?
HDI captures health and education alongside income, so it reflects wellbeing more fully than economic output alone.
Where does the data come from?
The UNDP Human Development Report, compiled via Our World in Data.
