The Happy Planet Index combines four elements to show how efficiently residents of different countries are using environmental resources to lead long, happy lives.

1. Wellbeing: How satisfied the residents of each country say they feel with life overall, on a scale from zero to ten, based on data collected as part of the Gallup World Poll.

2. Life expectancy: The average number of years a person is expected to live in each country based on data collected by the United Nations.

3. Inequality of outcomes: The inequalities between people within a country, in terms of how long they live, and how happy they feel, based on the distribution in each country’s life expectancy and wellbeing data. Inequality of outcomes is expressed as a percentage.

4. Ecological Footprint: The average impact that each resident of a country places on the environment, based on data prepared by the Global Footprint Network. Ecological Footprint is expressed using a standardized unit: global hectares (gha) per person.
