Population planning in Singapore has always been linked to economic pl
anning. Lacking natural resources on an island 536 sq. kms. in size, t
he physical carrying capacity was not large so that the government had
to resort to careful economic planning to overcome this constraint. T
he ''stop at 2'' population policy of 1965-87 was designed to support
the economic plans to improve the quality of life of the people. Restr
aint of population growth was promoted as a necessary move serving the
common good of Singaporeans as the country struggled in her early yea
rs of independence to build a nation. By 1983, however, Singapore swit
ched from being antinatal to being pronatal. The environmental determi
nism school that influenced population planning gave way to environmen
tal possibilism in which man is the main agent determining his own act
ions in the population-environment relationship. Technology has allowe
d the leadership of Singapore to make use of the global economy as its
hinterland. By concentrating on the high-end service sector, such as
mercantile banking or currency markets, Singapore has used the new inf
ormation age of computers to take advantage of the changing world mark
et. The ''quality'' population required to do this job is missing, thu
s the ''have 3 or more if you can afford it'' policy.
