Birth rates fell from 1957 to 1970, but then began to
rise as women of the postwar baby boom reached child-bearing
years.
The
government responded with policies intended to further reduce the
birth rate. Abortion and voluntary sterilization were legalized in
1970.
Between 1969 and 1972, a set of policies known as
"population disincentives" were instituted to raise the costs of
bearing third, fourth, and subsequent children.
Civil servants received no paid maternity leave for
third and subsequent children; maternity hospitals charged
progressively higher fees for each additional birth; and income tax
deductions for all but the first two children were eliminated.
Large families received no extra consideration in
public housing assignments, and top priority in the competition for
enrollment in the most desirable primary schools was given to only
children and to children whose parents had been sterilized before
the age of forty.
Voluntary sterilization was rewarded by seven days of
paid sick leave and by priority in the allocation of such public
goods as housing and education.
The policies were accompanied by publicity campaigns
urging parents to "Stop at Two" and arguing that large families
threatened parents' present livelihood and future security.
The penalties weighed more heavily on the poor, and
were justified by the authorities as a means of encouraging the
poor to concentrate their limited resources on adequately nurturing
a few children who would be equipped to rise from poverty and
become productive citizens.
Fertility declined throughout the 1970s, reaching
the replacement level of 1.006 in 1975, and thereafter declining
below that level.
With fertility below the replacement level, the
population would after some fifty years begin to decline unless
supplemented by immigration.
