Case study: the challenge of aging in
Japan
Q1- The regions least affected by aging
are the regions which have a percentage of evolution of
the population equal to 0 in 2010-2040. We could
explain it by a correct fertility rate, as well as the
low presence of elderly people. Contrasts
spatial demographics will increase as the
regions affected by aging are far from
large cities. They are isolated and therefore the
presence of young people na will only focus on
regions least affected by aging.
Q2- In 2018, the total population is 126 million
inhabitants, a big evolution compared to
1900s. Note that 28.4% of this
population are people over the age of 65,
a percentage that has greatly increased by more than
20% and which will continue in 2065.
58.9% are aged 15 to 65, which represents
enormously, more than half of this population
total. However, only 12.7% remain
belong to those under 15, a figure that has
greatly dropped since 1965 and continues to
fall year after year.
In 2065, the increase of people over 65 is
considerable with more than 10% in 47 years. However
a slight drop of 7.5% can be observed on the 15-
65 years. While the population under 15
continues its fall.
The forecast evolution is then an evolution of
elderly population as well as a loss of labor,
young workers. A population greatly affected
through aging.
Q3- The expected natural balance can be described as a decline
demographic with a fall in consumption,
of GDP and on the other hand an increase in debts
public.
