Answer:
A. Demography can help us plan for the needs of our population.
Explanation:
Demography is the statistical study of the population.
<u>It analyzes the size of the population and their various characteristics – </u><u>education, ethnicity, religion, nationality, places of origin, where they live, how old are they, etc. </u>
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,<u> 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.</u>
