Demography refers to the scientific study of human population and the demographer is a researcher involved in carrying out such scientific study. A demographer needs to answer several questions to determine whether a country is reaching its demographic transition. Some of these questions are as follows:
1. What is the birth rate of the population?
2. What is the death rate of the population?
3. What is the growth rate of the population?
4. How does the age-structure diagram of the said population looks?
5. Has there been decline in the death rate? Why?
6. Has there been a decline in the birth rate? Why?
7. Has there been a life threatening disease in the population?
8. Is the birth rate equal to the death rate?
