New results from statistics New Zealand show that 20% of 20- to 34-year-old men live with their parents — but only 13% of women in the same age range do. In Australia, 27% of men in the same age group live at home.
Here’s a quote from Bernard Salt, a social demographer, from an article from press.co.nz:
Men are living at home well into their 20s because they get free meals, free board, free laundry and free access to the family car. And you can have your girlfriend stay in your bedroom overnight, so why would you ever leave home?”
