Around 1/5 of the US population is elderly ~1/4 by 2050, add in moderately disabled people and this isn’t a small population we are talking about.

Paratransit is for a far smaller percentage of the population due to the significant expense.

So elderly that they can't walk to the bus? I suspect your data mean retirement age, i.e. 60-65+. They don't all need paratransit.
