The researchers studied the division of household tasks between intimate partners and how work hours, relative income, marital status and children's duties influenced housework at different life stages.
The results showed that:
• Men are most likely to pitch in when they are in their 20s if they earn less. Women generally do the housework, no matter what they earn;
• In their 30s, men are less likely to do housework if they work long hours and help with raising the children while women do chores despite this; and
• When couples are in their 40s, housework generally falls to women.
Horne said: "When couples are in their 40s, gender again becomes the biggest predictor of who will do what around the house."
