The latest survey of time use in America suggests women still 2 most of the housework, spending on average an hour a day scrubbing, hoovering and shopping, compared with barely 20 minutes for the unfairer sex. Standard 3 for this division of labour rest on the pay gap between the sexes. A recent report shows women still earn about 20% less than men in America. Couples can maximise earnings if the lower-paid(usually female)partner does the 4 work at home. But in a new paper Leslie Stratton of Virginia Commonwealth University asks whether different attitudes to housework also play a 5 in sharing the dusting. Mr Stratton draws on data from the Time Use Survey in Britain, which shows how people spent their day and which tasks they enjoyed. Attitudes certainly 6: women disliked laundry less than men. Ironing was generally dreaded; weirdly large numbers of both sexes liked shopping for food. Mr Stratton found some 7 for the pay-gap hypothesis. Women with higher wages did a little less work at home. A woman who earned 10% more than average ducked out of two minutes' housework per weekday. Her partner heroically 8this time at the weekend. But his wages made no difference to the extent of his efforts around the house. There is truth in the idea 9 chores go to the lower-paid partner. But cause and effect are 10. Do women do more because of lower pay, or might their careers suffer from a disproportionate burden at home?
