Chapter 33: Population Growth and Regulation
... Age Distributions Many MDCs have a stable age structure, but most LDCs have a youthful profile— a large proportion of the population is younger than age of 15. This means their populations will expand greatly in the near future. Zero population growth or replacement reproduction does not occur when ...
