American mothers’ and fathers’ perceptions of who does the most work when it comes to different parenting tasks

The survey was conducted among parents who are married to or living with an opposite-sex partner. The question about homework was asked only of parents with children ages 5 to 17, and the question about basic needs like feeding, bathing or changing diapers was asked only of parents with children younger than 5.
