The issue of population aging, recently discussed across the entire society, has greatly affected all generations of the society. The aging is a long-term and natural process that governments should be ready to accommodate if they want to keep the demographic situation stable despite the increasing fertility and decreasing mortality of inhabitants.
The resultant changes in population can be attributed primarily to better healthcare, to social and economic development and to new patterns of reproductive behavior. Developing countries have lately been experiencing a more rapid pace of population aging than the developed ones, where the process has had much longer history (United Nations, 2019).
