This chart shows the Percentage of Population aged 60 plus in 2015,2030 and 2050.
The world population has been experiencing significant ageing that results in rising proportions of older persons in the total population since the mid-twentieth century.Ageing has profound consequences on a broad range of economic, political and social processes. First and foremost is the increasing priority to promoting the well-being of the growing number and proportion of older persons in most countries of the world.
Ageing is a dynamic process, determined by the relative size of the younger and older cohorts in the population at different moments in time. The initial size of each cohort depends on the population in childbearing ages at a given point in time, and the prevalent fertility rates. Mortality rates determine the number of people of each cohort that survives to old-age. Migration may also affect ageing in different ways, although its actual impact at the national level is usually small.
