National Health Interview Survey, United States, 1985 and 2006§

* N = 23,679 (10,457 men and 13,222 women).

Based on response to the following question: "On average, how many hours of sleep do you get in a 24-hour period?" Respondents could indicate getting 1 to 24 hours of sleep.

§ Estimates were based on household interviews of a sample of the noninstitutionalized, U.S. civilian population.

From 1985 to 2006, the percentage of men and women who reported an average of <6 hours of sleep per 24-hour period increased in all age groups. In 2006, for both men and women, the percentage of respondents reporting <6 hours of sleep per 24-hour period was highest among those aged 30--44 years and 45--64 years.
