- war torn areas aren’t very common nowadays as reasons people would leave
- government policy is likely when moving from country to country but areas is also given in the question. Therefore it is not as likely of an answer
- land and resources is a valid answer for when areas were less urbanized; but also for when moving from country to country and less of area to area.
