2,000 surveys were fielded between April 10-18, 2019 among a representative sample of U.S. adults (age 18+), using a questionnaire lasting approximately 15 minutes. Sample size provides a confidence interval of ±2.19% at 95%. The sample was provided by Dynata, one of the largest online sample providers in the country.

Analysis was conducted to establish a Sleep Index (SI) that can be used to track America’s sleep quality over time. The SI is calculated using the following questions:
Q2. On average, how would you describe your sleep within the past two weeks?
Excellent | Very Good | Good | Fair | Poor |
5 | 4 | 3 | 2 | 1 |
Q7. Within the past two weeks, how often have you felt the following when you wake up in the morning?
Frequently
(10 to 14 times) |
Often
(6 to 9 times) |
Occasionally
(3 to 5 times) |
Rarely
(1 to 2 times) |
Never | |
Tired (want to continue sleeping) | 1 | 2 | 3 | 4 | 5 |
Rested/refreshed | 5 | 4 | 3 | 2 | 1 |
The multiplicative index was scaled so the average score was 100. The index was used to create three groups, as depicted below, for analysis purposes.

(SI ˃ 90 and SI < 110 |

The State of America’s Sleep survey suggested that work-related circumstances correlated with poor sleep. Employers who develop strategies to alleviate these work-related stressors should expect a positive impact on their employees’ sleep and increased productivity. Alternatively, employees who suffer work-related stress can change employers and seek a work culture that is more conducive to better sleep, improving their productivity by the same token.
Other factors outside of work also impact employees’ sleep. Employers and employees alike can have an impact on these factors to improve sleep and impact productivity at work. For example, employers who educate staff about ways to improve their sleep and develop strategies to help employees gain better sleep should be rewarded with improved productivity.
