Zero Population Growth

A situation in which the number of persons born in a population equals the number of persons who die. The fertility rate necessary for zero population growth varies, but is generally between 2 and 3. Some countries concerned about overpopulation aim for zero-population growth, while others dealing with an aging population may wish to increase the growth rate.
