Answer:
Step-by-step explanation:
Migration has been happening across the world for hundreds, if not thousands of years. People move from one place to another for various reasons (war, persecution, seeking better opportunities, unemployment, etc.). This migration of people can result in consequences for both the place they left behind and their new place of residence. These consequences can be economic, social, political, and demographic. Let's take a look.
Causes of migration
There are many different reasons why migration occurs. Let's take a look at the 'push and pull factor' idea, a helpful way of understanding the movement of migrants.
Push factors are the things going on in their place of residence that make people want to leave. Pull factors are those which attract people to a place.
Push factors for migration include:
Extreme weather (droughts, which can affect things like agriculture).
Lack of economic or social opportunities (work, school).
Lack of safety - (war, the threat to life, persecution).
