Gallup has measured daily stress in its tracking survey since 2008. Hawaii has ranked as the state with the lowest percentage of residents reporting stress on the prior day all five years and is the only state to rank in the top five consistently since 2008. West Virginia, Kentucky, and Utah, have each ranked within the top five most stressed states for the past five years. West Virginia ranked as the most stressed state in 2012, Kentucky was the top state for stress in 2008 and 2011, and Utah was the top state for stress in 2009 and 2010.

For all of the states, stress levels were statistically unchanged in 2012 compared with 2011. Regionally, states with stress levels at or above 42% were clustered in the Northeast and Midwest, but also included Utah, Oregon, and Washington.
