January-December 2011 Gallop-Healthways Well-Being Index

---

HOW DID GALLUP COME UP WITH THE DATA AND THE FORMULA FOR THESE SCORES?

The data was based on daily surveys conducted the entire year and is calculated on a scale of 0 to 100, where a perfect 100 represents ideal wellbeing.

The poll surveyed a random sample of 353,492 adults using random-digit-dial sampling during 2011. The maximum margin of sampling error is ±1 percentage point. They have been doing this tracking since 2008.

To compile the Well-Being Index, Gallup obtains completed interviews from 1,000 U.S. adults nationally, seven days a week, excluding only major holidays.

Based on their response, individuals and communities receive an overall well-being composite score and score of each of six sub-indices including life evaluation, emotional health, physical health, healthy behavior, work environment and basic access.

Changes in condition can be tracked over time, and the introduction of both controlled and uncontrolled variable considered. Discrete populations can also be ranked one against another for a stratified view of their relative well-being.
