These low variant population projections for China from the United Nations
Population Division can be used to demonstrate that even very small variations in
fertility assumptions have a huge impact on total population projections when the initial
population is very large.
Both the 1994 and the 1998 revision of the UN Population Projections use for 1990 an
initial population of 1.155 billion. With the fertility assumptions from the 1994 revision
the Chinese population was projected to increase to a little less than 1.2 billion people;
with the only slightly modified fertility assumptions from the 1998 revision, the
population was projected to increase to more than 1.25 billion. Please note that the
projected difference of 50.2 million people is only due to the
minimal difference in fertility assumptions of 0.07 children per woman (between 1990 and
2000) and 0.05 children per woman between 2000 and 2010. Of course, no one is able to
predict China's future Total Fertility Rate with a two-digit accuracy. In other words, we
have to expect that China's total population in 2050 can be only predicted with an error
range of at least 50 to 100 million people. |
