The U.S. Centers for Disease Control and Prevention have been conducting a huge survey of people's sleep. 403,981 people took part in the survey across all 50 states. Nearly 70% of people said that they had on bad night's sleep a month. Black people (13%) were most likely to say they never got enough sleep. 12% of women and 10% of men complained of an ongoing lack of sleep. West Virginia was the most sleep-deprived state with 19% of people being poor sleepers while North Dakota had the best sleepers with only 7% being affected.
