Demography: Shape your future

Since the advent of industrialization, the global population has been growing inexorably. By 2050, the number of people populating the earth will have risen to more than nine billion. But in contrast to previous eras, the main factor driving the growth of the global population today has been increasing life expectancy across the world. Conversely, birth rates are falling and the number of children (individuals below the age of 15) is likely to decrease slightly from 2020, while the number of people aged over 65 will increase by nearly one billion. There will therefore be dramatic changes in the age structure of the population.

Despite this trend being observed across the globe, there are substantial differences in the speed and extent of this change in individual countries. The key factors for demographic development are the onset of the decline in birth rate, the extent to which the rate slowed, and whether it will remain at the low level or rebound later on. Migrational movements are also extremely important for the devlopment of population size.
