The potential support ratio (PSR) is the number of people age 15–64 per one older person aged 65 or older. 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. In 2015, Japan has the lowest PSR in the world, at 1.8.
