Looking only at the availability of elevators may not fully illustrate the accessibility of a unit. A unit located on the tenth floor of a multi-story building without a working elevator is less accessible than a unit located on the third floor of the same building.

Data, presented in parentheses, indicate that the majority of people live in multi-family buildings with no more than five stories. The findings suggest that such buildings are unlikely to have elevators
