This ratio describes the burden placed on the working population (unemployment and children are not considered in this measure) by the non-working elderly population. [1] As a population ages, the potential support ratio tends to fall. Between 1950 and 2009, the potential ratio declined from 12 to 9 potential workers per person aged 65 or over.
