zero population growth
type: Concept
definition: Zero population growth (zpg) refers to a state in nature at which the birth rate is equivalent to the death rate, meaning that the population remains exactly at a specific level. There has been speculation about the appropriate level of population that may be sustainable given the restraints of existing economic and environmental resources.
