Question

Quizplus · Accepted Answer

Zero population growth refers to maintaining population at a steady level, with births and deaths balancing each other out. This means that the population neither grows nor declines in number over time. It does not refer to producing a perfect age-sex pyramid or keeping the sex ratio steady at 100, nor does it imply that the population will decline to zero.
