Story Highlights Hawaii and South Dakota round out top three well-being states 
 
 West Virginia ranks last for the sixth straight year 
 
 Hawaii and Colorado only states in top 10 every year since '08 
 
 This story is part of Gallup's annual "State of the States" series, which reveals state-by-state differences on political, economic, religion and well-being measures. 
 
 WASHINGTON, D.C. -- Alaska residents had the highest well-being in the nation in 2014, reaching the top spot for the first time since Gallup and Healthways began tracking well-being in 2008. West Virginia and Kentucky rank 50th and 49th, respectively, for the sixth consecutive year. Hawaii and Colorado are on the top 10 list of highest well-being states for the seventh consecutive year. 
 
 Alaska rejoins the top five in 2014 after being among this elite group from 2009 to 2011, while Hawaii finished in the top two for the sixth time, improving from the eighth spot in 2013. North Dakota tumbled from the top spot in 2013 to 23rd in 2014. North Dakota's drop was mostly attributable to a drop in its residents' overall life evaluation, coupled with worsened health-related behaviors such as higher smoking rates, reduced exercise and less healthy eating compared with 2013. 
 
 All of the 10 lowest well-being states in 2014 have frequented this list in the past. 
 
 These state-level data are based on more than 176,000 interviews with U.S. adults across all 50 states, conducted from January to December 2014. The Well-Being Index is calculated on a scale of 0 to 100, where 0 represents the lowest possible well-being and 100 represents the highest possible well-being. The Gallup-Healthways Well-Being Index score for the nation and for each state consists of metrics affecting overall well-being and each of the five essential elements of well-being: 
 
 Purpose: liking what you do each day and being motivated to achieve your goals 
 
 liking what you do each day and being motivated to achieve your goals Social: having supportive relationships and love in your life 
 
 having supportive relationships and love in your life Financial: managing your economic life to reduce stress and increase security 
 
 managing your economic life to reduce stress and increase security Community: liking where you live, feeling safe, and having pride in your community 
 
 liking where you live, feeling safe, and having pride in your community Physical: having good health and enough energy to get things done daily 
 
 Gallup and Healthways have been tracking well-being since 2008 and updated the Well-Being Index in 2014 to provide a more comprehensive measure of well-being. The Well-Being Index scores for 2014 are not directly comparable to the scores from prior years because they are calculated using the revised instrument and scoring methodology. However, state rankings for 2014 can be compared to rankings from previous years. 
 
 As in prior years, well-being in the U.S. exhibits regional patterns. The Northern Plains and Mountain West are higher well-being areas, along with some Western states and pockets of the Northeast and Atlantic. The lowest well-being states start in the South and move north through the industrial Midwest. 
 
 Hawaii, Colorado Lead All States With Most Top 10 Rankings 
 
 Hawaii and Colorado are the only two states to be in the top 10 for well-being every year since tracking began in 2008. In addition to these two states, 10 others have finished in the top 10 at least three times in the past seven years: Montana, Utah, Minnesota, Nebraska, North Dakota, Iowa, South Dakota, Alaska, Wyoming and Vermont. 
 
 Arkansas, Ohio, and Mississippi join West Virginia and Kentucky as the only states that have appeared among the lowest 10 well-being states in all seven years of tracking. 
 
 Hawaii and South Dakota Each Lead in Two of Five Elements of Well-Being 
 
 Alaskans, in addition to having the highest overall well-being, also had the highest ranking in purpose well-being across the nation. Hawaii (financial and physical) and South Dakota (social and community) each lead the nation in two elements of well-being. 
 
 West Virginia (purpose and physical) is the only state to rank last for more than one element in 2014. 
 
 Implications 
 
 Improving and sustaining high well-being is vital to any population's overall health and economy. Previous Gallup and Healthways research shows that high well-being closely relates to key health outcomes such as lower rates of healthcare utilization, workplace absenteeism and workplace performance, change in obesity status and new onset disease burden. Well-being is also a predictor of business outcomes such as employee engagement, customer engagement, turnover and workplace safety, which can affect a population's ability to reach its economic potential. 
 
 High well-being is also strongly related to important societal outcomes such as lower rates of teen pregnancy and crime, as well as higher high school graduation rates and more charitable giving. 
 
 Nationally, many aspects of well-being have improved in 2014 to their best levels since measurement began in 2008. For example, life evaluation, which is a key outcome of well-being and a high-level measure of how people think about and evaluate their lives, reached its highest recorded point in the U.S. in 2014. The rate of uninsured Americans fell to a low of 12.9% in the fourth quarter of 2014, indicating that millions of previously uninsured Americans now have insurance. And the Gallup Standard of Living Index reached a seven-year high of +50 by the end of 2014. 
 
 Other U.S. metrics point in the opposite direction. Obesity, for example, reached its highest point in 2014, climbing to 27.7%, and is now two full percentage points higher than in 2008. The rise in obesity coupled with improving metrics elsewhere illustrates the need for measuring well-being comprehensively, rather than focusing on one or two aspects. 
 
 Regardless of national trends, states' efforts to improve well-being should be customized to meet the needs of city and rural populations alike, always mindful of unique state subcultures. States and local communities can use well-being concepts and the five elements as focal points in designing and implementing initiatives to improve well-being. For example, Blue Zones Project initiatives in California, Minnesota, Iowa, Texas and Hawaii involve multifaceted programs and community actions aimed at improving many aspects of well-being. Specific interventions include working with schools, employers, grocery stores and restaurants to foster healthier choices. Other initiatives include working with governmental and other agencies to enact changes that increase opportunities for healthier lifestyles and community life, such as more walkable and bike-friendly environments, farmer's markets and social activities. But perhaps the most important aspect of a successful program is a strong, uniform and sustained voice from governmental and organizational leadership, which can play a pivotal role in providing the foundation upon which a culture of well-being can be built.

 Survey Methods 
 
 Results are based on telephone interviews conducted Jan. 2-Dec. 30, 2014, as a part of the Gallup-Healthways Well-Being Index, with a random sample of 176,702 adults, aged 18 and older, living in all 50 U.S. states and the District of Columbia. For results based on the total sample of national adults, the margin of sampling error for the Well-Being Index score is ±0.1 percentage points at the 95% confidence level. The margin of sampling error for most states is about ±0.6 percentage points, although this increases to about ±1.6 points for the smallest-population states such as North Dakota, Wyoming, Hawaii and Delaware. All reported margins of sampling error include computed design effects for weighting. 
 
 Each sample of national adults includes a minimum quota of 50% cellphone respondents and 50% landline respondents, with additional minimum quotas by time zone within region. Landline and cellular telephone numbers are selected using random-digit-dial methods.

 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. 
 
 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. 
 
 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. 
 
 States can implement initiatives to improve specific aspects of their residents' well-being — for example, they can work with schools, grocery stores and restaurants to include more wholesome food options, and they can work with the government and other entities to make changes that may improve community life, such as making areas more walkable or increasing the number of social activities, 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.

– Dark horse Alaska has come from behind to claim the title of the happiest state in the US, LiveScience reports. Snagging the designation from 2013 winner North Dakota, Alaska—which didn't even make the top 10 in 2013—topped Gallup's Well-Being Index in 2014 for the first time since tracking began in 2008. North Dakota crashed to the 23rd spot, while Hawaii, which has stayed in the top 10 every year, slid into second place. The top score, based on 176,000 interviews about health, finances, relationships, community, and purpose, fell from 70 out of 100 in 2013 to the mid-60s. Here's how other states fared: Alaska: 64.7 Hawaii: 64.5 South Dakota: 64.3 Wyoming: 63.9 Montana: 63.7 The unhappiest states: West Virginia: 59 Kentucky: 59.8 Indiana: 60 Ohio: 60.1 Mississippi: 60.2 Check out the full list or discover the world's happiest language.
