Having interviewed 100,000 people thus far, Gallup has published a happiness index that it hopes will offer some insight into the state of the nation's well being by - ahem - asking people how well they're doing. And as of earlier this year, 49 percent of people in the U.S. say that they're "thriving," compared to two percent in Cambodia and 83 percent in Denmark, according to Gallup.
The Gallup-Healthways Well-Being Index is billed as providing "unrivaled insight into the everyday emotional experience of Americans over time."
Hat tip: Freakonomics and Justin Wolfers, who has contributed several Freakonomics posts highlighting the relationship between politics, personal wealth, wealth distribution, and country of origin to happiness.
