The OECD study includes tasks like yardwork, etc. It encompasses all unpaid labor and is self-reported by both women and men. Unlike the BLS study, it's not just focused on household "chores" (relatively easy to see and divvy up) but also invisible/emotional labor -- tasks like finding childcare, finding contractors, locating medical care, dropping off/picking up children, emailing teachers, volunteering at school, signing field trip forms, etc etc. I could go on, but I'll spare you. This is the type of labor that's rarely acknolwedged and tends to fall largely to women who are in otherwise fairly equitable relationships.

You are correct that all efforts are valuable. So why are our country's paid caregivers making less than a living wage? Why do female-dominated fields pay less? Why do so many people ignore or refuse to acknowledge the mental/emotional toll of invisible labor? Why don't full-time unpaid stay-at-home parents receive Social Security benefits outside the context of their spouse? I will stop making work contribution a source of resentment when caregivers and teachers are paid what they're worth, when the Senate and House is comprised of 50% women, and when school PTAs are comprised of 50% men.
