It is a well-known
fact that the world population has been aging since mid-20th century. The
number of older people aged 60 years and above has more than quadrupled since
1950’s and older people’s share of the world population reached 11.7 percent in
2013.
The older
population itself is also aging. In 2013, 14 percent of the older population
consisted of those who were 80 years of age or older. The trend in aging is
expected to accelerate in the next four decades.
Population aging
has major implications for several sectors of the society. In the health
sector, these demographic changes will likely result in increasing pressures
for geriatric services.
