The Happy Planet Index measures what matters: sustainable wellbeing for all. It tells us how well nations are doing at achieving long, happy, sustainable lives.

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.
