What they do is have multiple family members per household. It's not that unusual to see two or more families living in what would normally be a single family dwelling. Across the street from my old house in San Mateo (Silicon Valley mid-peninsula), there were what appeared to be a husband and wife, the wife's sister, a cousin, three or four children, the sister or cousin's live in boyfriend, and a renter, all in a two bedroom, one bath house that was about 1200 square feet. Oh and a couple of dogs as well. It was notable because there were six or seven cars for the household, and there were only a couple of parking spots in front of each house, so they ended up parking their cars in front of our house often, forcing us to park down the street somewhere. If you have four or five adult wage earners at low wages you can make it work. Otherwise you have to live very far away from your job.
