Effects Of Aging Population
Current world population is around 7,320,000,000 people (United States Census Bureau, 2016), a figure that is predicted to surpass nine billion by 2050. Most of this additional rise will be seen in the developing regions of the world, most notably in Africa where fertility and mortality levels are still high. In contrast, the developed regions of the world will only experience a small rise in population. A figure that would be negative if it wasn’t for large projected net migration figures (United Nations Department of Economic and Social Affairs Population Division, 2009).
The ever increasing levels of population make for interesting study when comparing them against the changing demographic trends across the globe. Defined as a shift in age distribution of a population toward older ages, an aging population is a direct result of declining mortality figures, and declining fertility (Gavrilov & Heuveline, 2003). It is noted by Coleman (2001) and demonstarted in Figure 1, that the more developed countries slowly began to see the transition …show more content…
As seen in Figure 2, the proportion of global population over the age of 60 is predicted to increase substantially over coming years. In 2013, it was recorded that 11.7% of world population was aged above 60, this is a figure predicted to rise to 21.1% by 2050 (United Nations Department of Economic and Social Affairs, 2013).
For the majority of human history, most populations have seen relatively low growth with fertility and mortality being relatively stable (Gould, 2015). As the current situation of aging populations is something that has not been previously seen in human history, there are many questions and unknowns regarding the effect such a transition may have on not only global population structures but also global economic
