The Gallup-Healthways Well Being Index (http://www.well-beingindex.com) provides an assessment measure of health and well being of U.S. residents. By collecting periodic data on life evaluation, physical health, emotional health, healthy behavior, work environment, and basic access, this assessment measure is of immense value to researchers in diverse fields such as business, medical sciences, and journalism. The overall composite score, as well as a score in each of the above six categories, is calculated on a scale from 1 to 100, where 100 represents fully realized well-being. In 2009, the overall well-being index score of American residents was reported as 65.9. The overall well-being score of a random sample of 35 residents in California is in the Data file: Californians.xlsx
