How does Lee’s Push and Pull model explain migration?

Lee’s model of migration suggests there are pull factors and push factors within the origin country (where the migrant moves from) and the destination country (where the migrant moves to). Pull factors are factors that attract a person to move to a new area. Examples include higher wages, higher standards of living, higher standards of education and more job opportunities.Push factors are factors that force people to move from an area. Examples include drought, conflict, fewer job opportunities and poor standards of living.Another element of Lee’s model is intervening obstacles. These are factors that can prevent or make it more difficult for a person to migrate to another country. Examples include transport difficulties, passport and visa requirements or lack of money to migrate. In recent decades, intervening obstacles may have reduced for people trying to migrate. Globalisation has helped reduced these intervening obstacles. For example, with developments in transport technology, such as aircrafts, it takes a much shorter time for people to migrate elsewhere. Additionally, with the increased flow of information through communication websites, potential migrants can communicate with people who have already migrated to another country to gain an insight into their experiences of migration and their life in their new country.
