In 2008 the Centers for Disease Control and Prevention set out to learn just what determines how much sleep Americans get. The lowdown from the survey’s 403,981 respondents follows.
Women are more likely than men to get an insufficient amount of sleep. The results were 12.4 percent of women surveyed versus 9.9 percent of men.
Work helps you sleep. People who are employed get more rest than those who aren’t. But retirees get more sleep than either of those groups. (Only 9.5 percent of retired respondents reported not getting enough z’s.)
More education = more sleep. People with a college degree snooze more than those without a high school diploma or a GED.
Married and single people sleep roughly the same amount. But being divorced, widowed, or separated increases your likelihood of insufficient sleep.
Where you live affects your sleep. West Virginia has the highest rate of sleeplessness—more than 19 percent of respondents. For more sufficient sleep, head to North Dakota, where only 7.4 percent reported inadequate sleep.
The good news? The older you grow, the more likely you are to get enough sleep. People over the age of 65 reported the lowest percentage of insufficient sleep.
