Migration Theory explains the reasons and patterns behind human movement from one place to another. It encompasses various factors, including economic opportunities, social networks, and environmental conditions. The theory helps to understand why people leave their home countries and what influences their destination choices. Different models within Migration Theory, such as the Push-Pull Model, identify "push" factors that drive people away, like conflict or poverty, and "pull" factors that attract them, such as job availability or better living conditions. This framework aids researchers and policymakers in addressing migration's impacts on societies and economies.
