10.9 billion. [2;7] The medium projection also points to global
population peaking around 2040 and then starting to fall.
I wrote the first version of this paper in 1996. In revising it,
I found it interesting that, less than a decade ago, the higher
projection allowed for 12 billion or more. Demographers had
continued their long tradition of over-estimating population
growth. This effect seems to have been reduced, but take all
projections (especially those longer than a generation) with a
healthy dose of skepticism.
FORCES OF POPULATION DECELERATION
Why, though, should we expect people in less developed
countries, even given contraceptives, to continue choosing to
have smaller families? This expectation is not merely specu-
lation based on recent trends. Sound economic reasoning
explains the continuing trend, and makes sense of why the
poorer nations are only just beginning to make the transition
to fewer births.
Decelerating population growth appears to be an inevitable
result of growing wealth. Early on in a countrys developmen-
tal curve, children can be regarded as producer goods (as
economists would say). Parents put their children to work on
the farm to generate food and revenue. Very little effort is put
into caring for the child: no expensive health plans, special
