Explanation:
Population migrations are constant, and throughout history, they are an integral part of human nature. Sometimes the road to a better life can be tough, and hundreds of thousands of people throughout history have lost their lives when going to a better world. People in groups never migrate from natural needs. The reasons for migration are always caused by the inability to live a healthy life.

Often throughout history, migrations have also been affected by populations fleeing natural disasters. Natural disasters throughout history have often destroyed entire regions, cities, leading to the movement of survivors in these environments.
