The birth rate at which there is no net increase in population—a goal of some birth control programs—and the number of births equals the number of deaths

zero population growth

,

ZPG

The demographic equilibrium in which in a given period of time the population neither increases nor decreases, that is, the death and birth rates are equal.

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)
