what is a migration

Migration is the movement of people from one place to live in another. Emigrants leave their country, while immigrants enter a country. Migration impacts on both the place left behind, and on the place where migrants settle. People have many reasons why they might want to move from one place to another. These reasons may be economic, social, political or environmental. For migration to take place there are usually push factors and pull factors at work. Push factors are the reasons that make someone decide to move. This is their own experience of life in one place which gives them good reasons to leave it. Often push factors are negative things such as unemployment, crop failure, droughts, flooding, war, poor education opportunities or poor services and amenities. Pull factors, on the other hand, are the expectations which attract people to the new place. They are usually positive things such as job opportunities, a better standard of living, better education or better healthcare.
