         In 
        designing certain features of our built physical world, one should try 
        to accommodate all the population in question. 
        ¡@ 
        A specific 
        design dimension or feature is a limiting factor that might restrict the 
        use of the facility for some people. 
        ¡@ 
        That 
        limiting factor can dictate either a "maximum" or minimum" value of the 
        population variable or characteristic ¡@  |
