According to Gallup, D.C. is the happiest place in America. Well, not quite, but it is the leading metropolitan area with a population over a million when it comes to well-being. Here's how they define well-being:

The Gallup-Healthways Well-Being Index score is an average of six sub-indexes, which individually examine life evaluation, emotional health, work environment, physical health, healthy behaviors, and access to basic necessities. The overall score and each of the six sub-index scores are calculated on a scale from 0 to 100, where a score of 100 represents the ideal. Gallup and Healthways have been tracking these measures daily since January 2008.

D.C. scored 71.3 out of 100, just narrowly beating out the San Francisco-Oakland-Fremont area's 71 and San Jose-Sunnyvale-Santa Clara's 70.8. This good news should keep people happy and keep that well-being score relatively high.
