Slate has an article about the latest study of how much difference there is between the amount of work men and women do. According to this study,
The 24 hours we all have each day can be divided into four broad activities: “market work” that is, work for pay, typically outside the house; “homework,” including housework and child care; “tertiary time,” including sleep, eating, and other biological necessities that people can do only for themselves; and the time left over, which is leisure. Leisure is not essential to survival, but we like it.
Throughout the world, men spend more time on market work, while women spend more time on homework. In the United States and other rich countries, men average 5.2 hours of market work a day and 2.7 hours of homework each day, while women average 3.4 hours of market work and 4.5 hours of homework per day. Adding these up, men work an average of 7.9 hours per day, while women work an average of—drum roll, please—7.9 hours per day.
The Slate writer observes, “Although men in many rich countries do not work less than women, they do enjoy about 20 to 30 minutes more leisure per day (over an hour more in Italy) because they spend less time on sleep and other biological necessities. Men spend almost all of this additional leisure time watching television.”
