You're not adjusting for inflation, which they are. Still, I have no idea where they're getting their numbers, which seem comically wrong.

> Accounting for inflation, house prices have soared by 118% since 1965, despite the fact that income has only increased by 15%.

They use the median for that, which seems to have actually increased by 60%:

I'm not sure why nobody else seems to have brought this up- it's a serious flaw in the article.
