National Sleep Foundation's Sleep in America Poll

The 2005 Sleep in America Poll (55 pages, PDF) of the National Sleep Foundation finds that adults in the United States sleep 6.8 hours a night on weekdays and 7.4 hours a night on weekends. About half the poll respondents — primarily those fifty years old and older — reported having a good night's sleep every night or almost every night, while 26 percent claimed to enjoy a good rest only a few nights a month or less. When asked if they feel more alert, productive, and energetic in the morning or in the evening, 55 percent of respondents admitted to being larks, and 41 percent considered themselves owls.
