For the third straight year, Hawaii holds onto its title as the happiest state in America according to the annual Gallup-Healthways Well-Being Index.

The nationwide survey is based on daily interviews with U.S. adults from January to December 2011. The Index is an average of six categories: life evaluation, emotional health, work environment, healthy behaviors, and physical health.
