Answer:
A. Demography can help us plan for the needs of our population.
Step-by-step explanation:
Demography is the statistical study of the population.
It analyzes the size of the population and their various characteristics – education, ethnicity, religion, nationality, places of origin, where they live, how old are they, etc.
With this information, various conclusions about people and their needs can be gathered. For example, we can get how educated the population is, and see if there is a need for better education and more facilities, or we can see if the average population is too old and “dying out” and if there is a need for benefits to the new families, etc.
Therefore, by studying the information gathered with demography, we can learn about the needs of the population and plan changes and policies in order to meet them.
