– Describe and suggest reasons for the rapid increase in the world’s population in recent times, ‘the population explosion’.
– Define the main components influencing population growth – birth rate, death rate and migration.
– Describe the relationship between population growth and resources and explain why problems may result in some areas such as over-population and underpopulation.
– Identify and suggest reasons for contrasting patterns of population growth in different world areas as influenced by differences in birth rate, death rate and migration. Factors affecting these influences should be considered such as differences in social, economic and other factors, e.g. government policies and their impact upon birth rates, differences in health care, social and other factors influencing death rates, especially the impact of HIV/AIDS. These factors should be illustrated by reference to selected examples.
