(AP Photo/Maria Fisher) (Newser) – US citizens who want a happier life may want to leave the country. The Gallup-Healthways Global Well-Being Index has issued its second annual list of country rankings, looking at 145 countries and how their residents fare in various "well-being elements." Those elements: a sense of purpose, social relationships, financial security, a sense of community, and physical health. The rankings are based on the percentage of people in each country thriving in three or more of the areas. The top 10 countries: Panama (53%) Costa Rica (47.6%) Puerto Rico (45.8%) Switzerland (39.4%) Belize (38.9%) Chile (38.7%) Denmark (37%) Guatemala (36.3%) Austria (35.6%) Mexico (35.6%) The US sits at No. 23.
