The 60 hours of work a week for homemakers comes from a book called "More work for mother." It is a figure that has been stable for 300 years. I don't recall where specifically I got some of the other figures. I was trying to sort my life out, not prepare for debate on an internet forum I had not yet heard of and which did not exist when I was doing a lot of this reading in my 20s.
