=+26. Gallup Poll, part 2. The Gallup-Healthways WellBeing Index tracks daily how Americans evaluate their lives, both now and in five years, on the Cantril SelfAnchoring Striving Scale, where “0” represents the worst possible life and “10” represents the best possible life.

Respondents are classified by Gallup as “thriving” if they rate their current life a 7 or higher and their future life an 8 or higher. Daily results are based on a three-day rolling average, based on telephone interviews with approximately 1000 national adults. As of March 1, 2012, Gallup reported that 530 of 1000 adults were thriving.
