A new study comparing self-described pleasant feelings with objective measures of good living found these folks generally have reason to feel fine.
The places where people are most likely to report happiness also tend to rate high on studies comparing things such as climate, crime rates, air quality and schools.
The happiness ratings were based on a survey of 1.3 million people across the country by the Centers for Disease Control and Prevention. It used data collected over four years that included a question asking people how satisfied they are with their lives.
Economists Andrew J. Oswald of the University of Warwick in England and Stephen Wu of Hamilton College in Clinton, N.Y., compared the happiness ranking with studies that rated states on a variety of criteria ranging from availability of public land to commuting time and local taxes.
Probably not surprisingly, their report in today's edition of the journal Science found the happiest people tend to live in the states that do well in quality-of-life studies.
Yet Mr. Oswald says "this is the first objective validation of 'happiness' data," which is something he says economists have been reluctant to use in the past.
"Very loosely, you could say that we prove that happiness data are 'true,' such data have genuine objective informational content," he said.
"Moreover," Mr. Oswald added, "it is interesting to uncover the pattern of life-satisfaction across one of the world's important nations."
Ranking No. 1 in happiness was Louisiana, home of Dixieland music and Cajun/Creole cooking.
Mr. Oswald urged a bit of caution in that ranking, however, noting that part of the happiness survey occurred before Hurricane Katrina struck the state, and part of it took place later.
Nevertheless, he said, "We have no explicit reason to think there is a problem" with the ranking.
Rounding out the happy five were Hawaii, Florida, Tennessee and Arizona.
At the other end of the scale, last in happiness -- is New York state.
As if to illustrate the problem, residents attending a meeting Wednesday in rural Queensbury unleashed their anger and cynicism at a state government they described as corrupt, self-dealing and too quick to increase taxes. It was a tirade that had one lifelong resident saying he was ready to flee "this stinkin' state."
Mr. Oswald suggested the long commutes, congestion and high prices around New York City account for some of the unhappiness.
He said he has been asked if the researchers expected that states such as New York and California, which ranked 46th, would do so badly in the happiness ranking. "I am only a little surprised," he said.
