Statistically speaking, anyways. Every year, Gallup polled randomly selected American adults about their lives, including how happy they are:
The New York Times asked Gallup to come up with a statistical composite for the happiest person in America, based on the characteristics that most closely correlated with happiness in 2010. Men, for example, tend to be happier than women, older people are happier than middle-aged people, and so on.
Gallup’s answer: he’s a tall, Asian-American, observant Jew who is at least 65 and married, has children, lives in Hawaii, runs his own business and has a household income of more than $120,000 a year.
Does that person actually exist? The New York Times went a-sleuthin':
A few phone calls later and ... Meet Alvin Wong. He is a 5-foot-10, 69-year-old, Chinese-American, Kosher-observing Jew, who’s married with children and lives in Honolulu. He runs his own health care management business and earns more than $120,000 a year.
