The article describes the nature of population policies during the las
t half-century, with focus mainly but not exclusively on what is defin
ed as the 'hard' sector of the policies, in designing interventions -
mainly the area of fertility control. Concerns that population growth
is too rapid emerged after the destructions of the Second World War, w
hen the acceleration of the rate of growth in the poor world became ev
ident. Japan's experience in reducing the rate of growth opened the wa
y to other experiences which, however, became successful only in the 1
970s and 1980s. The article describes the emergence of an internationa
l consensus on population issues, focuses on a few significant experie
nces, like those of China and India, and discusses some of the major c
ontroversies of the current debate, notably the role of 'demand' and '
supply' oriented policies.
