Gallup Daily: U.S. Life Evaluation
Based on the Gallup-Healthways Well-Being Index
The Gallup-Healthways Well-Being Index tracks daily how Americans evaluate their lives, both now and in five years, on the Cantril Self-Anchoring 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. Respondents are classified as "suffering" if they rate their current life 0 to 4 and their future life 0 to 4. Those who are neither "thriving" nor "suffering" are classified as "struggling." Daily results are based on a three-day rolling average, based on telephone interviews with approximately 1,000 national adults; margin of error is ±4 percentage points.
