For the last three years, Gallup has called 1,000 randomly selected American adults each day and asked them about their emotional status, work satisfaction, eating habits, illnesses, stress levels and other indicators of their quality of life.

It’s part of an effort to measure the components of “the good life.” The responses are plugged into a formula, called the Gallup-Healthways Well-Being Index, and then sorted by geographic area and other demographic criteria. The accompanying maps show where well-being is highest and lowest around the country.
