Your paper should be argumentative in character, which means you need to develop your own perspective on the issue. In developing your argument, consider the following:
1) What is your thesis (meaning, what is your main point)?
2) What do other people have to say about this issue (these ‘people’ are your research)?
3) Why is this topic important within Population Geography?
4) Why is this topic important where your study focuses?
5) Can you offer a projection on the future of this issue within your specific context?
However, this is an essay, so you should not address these in turn, but should consider them within your paper.
