doubling time

|
demographic transition
|
a model of the effect of economic development on population growth. the first stage involves both ihgh birth and death rates; the second phase displays high birth rates and falling mortality rates and population increases. Phase three shows reduction in population growth as birth rates decline to the level of death rates. The final, fourth , stage implies again a population stable in size but larger in numbers than at the start of the transition cycle.
