The U.S. ranks second, just 12 minutes behind at about 8.6 hours of sleep per day. People in Korea and Japan get the least sleep at about 7.8 hours per day.

The report indicates that Americans work an average of 41.3 hours per week. People in France work an average of 37.3 hours per week.
A 2007 study in the journal Sleep analyzed data from previous American Time Use Surveys. Results suggest that work time is the strongest indicator of sleep time.
Tomorrow we’ll take a closer look at the survey data. We’ll see what it does and doesn’t tell us about the sleep of people in the U.S.
