What causes rapid population growth?
Several factors are responsible for the rapid growth: a drop in mortality rates, a young population, improved standards of living, and attitudes and practices which favor high fertility.
How does migration affect growth rate?
The rate of population growth is the rate of natural increase combined with the effects of migration. Thus a high rate of natural increase can be offset by a large net out-migration, and a low rate of natural increase can be countered by a high level of net in-migration.

What is rapid population growth rate?
Rapid growth of population is known as Exponential growth where the population is increased with the constant increasing birth rate and is never limited to food and diseases. The birth rate alone controls the growth of population. This accelerating pattern of increasing population size is called as exponential growth.
What is the cause of high growth rate of population?
This rapid growth increase was mainly caused by a decreasing death rate (more rapidly than birth rate), and particularly an increase in average human age. By 2000 the population counted 6 billion heads, however, population growth (doubling time) started to decline after 1965 because of decreasing birth rates.
