alt Hacker News>we have historically low average number of people per house.
I'd like to see the actual statistics method used to calculate that. Saying it's marriages alone just doesn't past the smell test for me. Just because people aren't married doesn't mean they don't live together and the number of unmarried people living together is higher than ever. What makes far more sense is the number of children people have has fallen off a cliff which drastically drops the number of live at home adult children.

It's basically this graph. In 60's almost nobody was living alone (less than 400k people). In 2024 about 3,3 million people live alone. When you look at the infographic, ages 30-60 add up to like 1,2 million people.

Here we have an estimation that the country is missing like 400k houses. So if two-thirds of those 1,2 million married each other and started living together, they would nicely plug the housing crisis by freeing 400k houses.
Either way, we have a huge societal change that lots of people live alone, which did not use to be the case.
People living together out of necessity (roommates) still has the optics of a housing crisis of those people wish they didn’t live together. This is the opposite for couples who want to live together.
