American Time Use Survey

The American Time Use Survey (ATUS) measures the amount of time people spend doing various activities, such as paid work, childcare, volunteering, and socializing.
For example - in 2009, employed persons worked an average of 7.5 hours on the days that they worked; they worked longer on weekdays (7.9 hours) than on weekend days (5.0 hours). Eighty-five percent of women and 67 percent of men spent some time doing household activities such as housework, cooking, lawn care, or financial and other household management on a given day.
