Does anyone know what percentage of urban dwellers remain in the city for their lifetime? I would imagine this number tracks inversely to the decreasing birth rate YoY decline (among this same demographic group) in the US. Specifically, I&#x27;m interested in the birthrates for the 50-75th income percentile for living in major cities (not metropolitan areas).<p>A couple cursory Google searches hasn&#x27;t yielded any hard data, but hopefully someone has come across data on this.<p>tldr; I don&#x27;t disagree with your assumption for decreased ownership for personal transportation, but I don&#x27;t see this changing for families that live outside the Urban core until decades from now.
