Its purpose was to assess which country offered the most favorable conditions for a healthy, secure, and prosperous life in the years following its release.
[1] It was based on a method that combines the results of subjective life-satisfaction surveys with the objective determinants of quality of life across countries as well as forecasts for economic growth.
The survey considered ten quality-of-life factors and future GDP per capita forecasts to determine each nation’s score.
[3] Back in 2006, life satisfaction scores (rated on a scale of 1 to 10) for 130 countries (from the Gallup Poll) were analyzed through multivariate regression.
These predicted scores represent a country’s quality of life index, with coefficients automatically weighing the importance of different factors.
