The rankings of national happiness are based on a Cantril ladder survey. Nationally representative samples of respondents are asked to think of a ladder, with the best possible life for them being a 10, and the worst possible life being a 0. They are then asked to rate their own current lives on that 0 to 10 scale (i.e.Happiness Scores in this project). The report correlates the results with various life factors. Six measurements are taken per country:

Freedom

Generosity
