The nation's largest and most northern state scored highest in the 2014 Gallup-Healthways' annual survey of well-being, with a score of 64.7 out of 100. Alaska has previously ranked among the top 10 happiest states, but this is the first year it has been the winner since the survey began in 2008.
盖洛普2014年幸福指数调查显示,全美最大以及最北边的州取得了最高分64.7(总分为100)。阿拉斯加一直被列为全美最幸福的10个州之一。自2008年盖洛普调查发布以来,这是其首次位列第一 。

In second place was Hawaii, which held the top spot from 2009 to 2012, but in 2013 came in eighth. The winner in 2013, North Dakota, saw a dramatic drop in its ranking, coming in 23rd in 2014. This drop was mostly due to a decline in North Dakotans' evaluation of their lives overall, and also an increase in unhealthy behaviors among the population, such as higher smoking rates and less exercise, compared with 2013, Gallup said.
排名第二的夏威夷垄断了2009年至2012年的第一,但在2013年跌至第8。去年排第一的内达科他州,今年出乎意料般的跌至23。盖洛普报告表示, 内达科他州的这种情况主要源自居民生活方式的变化,例如和2013年相比更高的吸烟率,更少的体育锻炼。

The rankings are based on interviews with more than 176,000 U.S. adults in all 50 states. The researchers calculated a well-being score for each state, based on participants' answers to questions about different aspects of well-being, such as their sense of purpose, social relationships, financial lives, community involvement and physical health. 

States in the Northern Plains and Mountain West tended to have higher well-being scores than states in the South and Midwest. Kentucky and West Virginia came in at the bottom of the rankings for the sixth year in a row, Gallup said.

A population's well-being is important because it is closely tied to people's health and work abilities, such as obesity rates, workplace performance and employee engagement, Gallup said.

The Gallup-Healthways Well-Being Index was conducted between Jan. 2 and Dec. 30, 2014, and its well-being score has a margin of error of about 0.1 percentage points.
