       On the clock at 2 a.m.

Whos working at 2 a.m.? Data from the U.S. Bureau of Labor Statistics (BLS) can tell you. According to the BLS American Time Use Survey, more than 3 percent of all full-time workers aged 15 and over were at their primary job at 2 a.m. on the day that they were surveyed. The chart shows the occupational groups that were most likely to have workers clocked in at this early hour.

Occupations of many working night owls are not surprising. Protective services workers must work around the clock to keep people and property safe. And healthcare workers are on call at all hours in hospitals and nursing homes. But workers in other groups might be more unexpected, such as the almost 6 percent of workers in farming, fishing, and forestry occupations toiling at 2 a.m.

The American Time Use Survey gathers detailed information on how Americans spend their time. Data are averaged across 4 years, 2003 to 2006. For more information about this survey, write to BLS, 2 Massachusetts Avenue NE., Suite 4675, Washington, D.C. 20212; call (202) 6916339; or visit
