The inverse dependency ratio is an indicator that gives insight into the amount of people of nonworking age compared to the number of those of working age. It is defined as the ratio between the number of dependents, (aged zero to 14 and over the age of 65,) and the number of the total population, aged 15 to 64.
A high ratio means those of working age, and the overall economy, face a greater burden in supporting the aging population.
