I should add that I live with another person, who does his share of the chores, so this time would probably increase if I wanted the same level of clean/tidy while living alone. I’m not sure how time per person scales with changes in the number of people though… probably not linearly, but it must depend on all sorts of things like how exactly you share out the chores, what the overhead sort of times are like for doing a task once regardless of how much task there is, and how size of living space changes with respect to number of people living in it. Also, if you add actively non-useful people like babies, I expect all hell breaks loose.
