zero population growth (ZPG)

a state in a population in which births equal deaths, so that overall numbers remain in a steady state. ZPG (or even negative growth) has been achieved in many Western countries where the family size is low but has, so far, proved an impossible target for most Third World countries, the state being achieved only where there is widespread use of contraceptives (see BIRTH CONTROL, DEMOGRAPHIC TRANSITION)
