Essay on Aging Populations : 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 toward an older population in the early part of the 19th centuary, thus giving hundreds of years to adjust to the situation faced today. However, rapidly developing countries have only started to see this transition in the last 20-30 years, meaning that the period of adjustment has been minimal, therefore unique challenges have arisen.
Population aging is a phenomenon now occurring in the majority of…
