What are the factors that influence population growth?

Answer 1

In ancient times, population grew as food became plentiful, people were well-nourished, and life became easier.

However, today culture determines most population growth. Factors include religious/cultural taboos as well as economic prohibitions against birth control, plus illiterate women. Some families want to have many children in order to make sure that some will survive and grow up to help their parents in their old age.

Population growth of a particular country also depends upon its immigration policies.
