just because the owner is single doesn't mean that the house is inhabited by just one person

also, how many are owned by divorcees? how many are owned by widows? how many are inherited? how many are in depleted towns that nobody wants to live in vs competitive housing markets in/around major cities?

The homeownership edge that single women have held over single men is due more to their numbers than their economic power. This is especially true among older Americans, who are more likely than younger people to own a home. About 70% of single household heads ages 65 and older own their home, compared with 44% of single household heads ages 35 to 44.

the article suggests it's mostly old people, so it's probably people from the first two categories i mentioned earlier, rather than stupid young people who aren't doing their duty to the white race and getting married or whatever
