Three indicators of Human development:
The access to resources, health and education are the key areas in human development. Suitable indicators have been developed to measure each of these aspects.
The indicator chosen to assess health is the life expectancy at birth. A higher life expectancy means that people have a greater chance of living longer and healthier lives.
The adult literacy rate and the gross enrolment ratio represent access to knowledge. The number of adults who are able to read and write and the number of children enrolled in schools show how easy or difficult it is to access knowledge in a particular country.
Access to resources is measured in terms of purchasing power (in U.S. dollars).
