Chore Wars: Men, Women and Housework

Study confirms wives do most household chores

Husbands create an extra seven hours a week of housework for wives, according to a new study. But wives save husbands from about an hour of housework a week.

Based on a representative sample of all U.S. families, the study of housework trends was released April 3 by the University of Michigan in Ann Arbor as part of the world's longest running study on income dynamics.

"There's still a significant reallocation of labor that occurs at marriage," says economist Frank Stafford, who directs the study. "Men tend to work more outside the home, while women take on more of the household labor. Certainly there are all kinds of individual differences here, but in general, this is what happens after marriage."

Conducted since 1968 by the university's Institute for Social Research, the Panel Study of Income Dynamics (PSID) is funded by the National Science Foundation (NSF). It's a long-term, nationally representative study that collects data on the economic, health and social behavior of the same, nearly 8,000 U.S. families year after year.

"The PSID is the only instrument that lets us look at income mobility, people moving in and out of poverty, across three generations," says Dan Newlon, project manager for NSF. "The data allows us to look at the mid- to long-term socioeconomics of household dynamics."

Based on 2005 data, which have been compared to those from national time diaries, the research shows women, of all ages with no children, on average do 10 hours of housework a week before marriage and 17 hours of housework a week after marriage. Men of all ages with no children, on the other hand, do eight hours before marriage and seven hours afterwards.

"The situation gets worse for women when they have children," says Stafford.

Married women with more than three kids recorded an average of about 28 hours of housework a week, while married men with more than three kids logged only about 10 hours of housework a week.

According to the study, housework was defined as "core chores," or routine housework that people generally do not enjoy doing such as washing dishes, laundry, vacuuming floors and dusting.

"Routine housework, like cooking dinner or making beds, was captured in diaries, the primary tool used for the study of time allocation," says Stafford. Researchers supplemented the diaries with data from questionnaires asking both men and women to recall how much time they spent on basic chores in an average week.

Other activities such as home repairs, mowing the lawn, and shoveling snow were not in the study. "Items such as gardening are usually viewed as more enjoyable; the focus here is on core housework," says Stafford.

He says the fact that people generally do not enjoy core housework may explain the reason for so-called 'chore wars' between men and women. It may also explain the long steady decline in total core housework per week accomplished by both sexes.

Overall, U.S. women do considerably less housework today than in 1976, while the amount of housework men do has increased. In 1976, women did an average of 26 hours of housework a week, compared with about 17 hours in 2005. Men did about six hours of housework a week in 1976, compared with about 13 hours in 2005.

Single women, in 2005, who were in their 20s and 30s, did the least housework--about 12 hours a week on average, while married women in their 60s and 70s did the most--about 21 hours a week. The pattern for men was different. Older men did more housework than younger men, but single men did more in all age groups than married men.

"There has been an extraordinary increase in the number of women working outside the home over the last 30 years," says Newlon. "This study shows with men and women working, men still lag women in housework."
