This figure presents the results of a
probabilistic projection of China's children under the age of 15 prepared by the
Population Division of the United Nations Department of Economic and
Social Affairs.
The projection is based on
probabilistic projections of total fertility that have been used in
the 2010 Revision of the World Population Prospects. For this
projection 5,000 trajectories of total fertility were randomly
sampled from the original 100,000 probabilistic trajectories of
total fertility that were calculated using a Bayesian Hierarchical
Model (BHM). Methodological details of the probabilistic model are
available
here. The results of the
probabilistic fertility projections have been published
here.
As illustrated by this
figure, China's population age 0-14 has been declining since 1975
and is projected to decline further to around 140 million by the end of the century. It is very likely for
Chinas population under the age of 15 to decline in the future as
indicated by the 80% confidence interval for a decline. There is
only a 1 in 40 chance for China's population under 15 to
stagnate or slightly increase..
