The document defines several key demographic terms related to population such as crude birth rate, total fertility rate, and crude death rate. It then discusses factors that contributed to the global population explosion in the 20th century, including declining death rates and high birth rates in developing countries. It also covers population growth rates, doubling times, and UN projections for future world population growth and trends toward slowing growth rates.

14. How do we measure development?

16. What demands will population and development changes place on the worlds human and physical resources? What will the implications of these demands be in terms of sustainable development?

19. Personal Investigation Your enquiry should aim to investigate the relationship between development and one of the key demographic indicators associated with fertility , mortality and natural population change .
