The term used by gerontologists to gauge the burden that the old (and the young) place on people in middle age is the overall dependency ratio. This ratio compares the number of dependent individuals (under 15 and over 64) to the number of individuals in the working-age population (15-64). The higher the dependency ratio, the greater the burden on the working-age population to support the young and old.
