Quizplus · Accepted Answer

The dependency ratio for high-income countries has increased primarily because life-spans are longer, often as a result of improved healthcare and living conditions. This leads to a larger proportion of the population being in the dependent age groups (either young or old), especially the elderly, following a period known as the demographic window when the working-age population was exceptionally large compared to the dependent population.
