Glossary H
The Human Development Index (HDI) is a statistic composite index of life expectancy, education (mean years of schooling completed and expected years of schooling upon entering the education system), and per capita income indicators, which is used to rank countries into four tiers of human development. A country scores a higher level of HDI when the lifespan is higher, the education level is higher, and the gross national income GNI (PPP) per capita is higher.

A hazard is a situation that poses a level of threat to life, health, property, or environment.

A hazardous situation that has come to pass is called an incident. Hazard and possibility interact together to create risk.
