It would also be interesting to see the numbers relative to mortgage rates and availability. It looks like the 1950's had mortgages starting around the 5% range, but that steadily increase to a peak of near 20% in the 80's before dropping through the 90's and bottoming out around 2.5% in 2021. Along with that I imagine qualifying / getting a mortgage in 1950's was more difficult than modern times with 0% down first time home buyer loans.
