“Gallup’s global wellbeing surveys in 2010 reveal that a median of 21% across 124 countries were “thriving” last year, based on how people rated their lives at the current time and their expectations for the next five years. This is unchanged from a median of 21% in 2009. The percentage rating their lives well enough to be considered thriving ranged from a high of 72% in Denmark to a low of 1% in Chad. Gallup classifies respondents’ wellbeing as “thriving,” “struggling,” or “suffering,” according to how they rate their current and future lives on a ladder scale with steps numbered from 0 to 10 based on the Cantril Self-Anchoring Striving Scale. People are considered thriving if they rate their current lives a 7 or higher and their lives in five years an 8 or higher.”
