Something I am curious to see is the "share of housing inventory owned by each age group" over the years. For example, "25% of housing is owned by people over 75 years old, 50% 55-75, 25% under 55", etc. broken down for each year.<p>Basically, I suspect that today a larger share of homes are owned by the older generations, making it more and more difficult over time for young families to find houses to buy. A crude way to phrase this would be that the older generations are hoarding all the housing supply. The older generations are increasing in numbers and financial means, and the housing supply is not increasing fast enough to give the younger generations the same opportunities to buy.<p>The end result of this seems to be a massive wealth shift to the older generations, leaving the current younger generations less well-off than their parents were at the same age. This seems to be the opposite of what you want to see in a well functioning society.
