Aleks04 [339]

Push factor: many immigrants came to America from Ireland to escape a famine.

Pull factor: many Chinese immigrants came to America to work in new jobs, like building the transcontinental railroad.

Push factor: many Russian Jews migrated to America to escape harsh mistreatment.

Pull factor: many Scandinavians were encouraged to migrate by the land that the homestead act of 1862 made available.

Migration refers to the movement of the population from one place to another with the desire to settle down at that new location temporarily or permanently. There are certain forms of migration like:

  • Internal migration: moving within a state or country.
  • External migration: moving to a different state, country, or continent
  • Emigration:  leaving one place to move to another
  • Immigration: moving into a new place
  • Return migration: moving back to the place of origin
  • Seasonal migration: moving with each season

There are two types of a factor of migration:

  • Push factors: These are the negative factors that compel people to leave their place and move to a new location since no positive opportunities were available in the previous area. These factors include low employment, poverty, war, lack of services, and so on
  • Pull factors: These are the positive factors that attract people to move to a new place with a good environment and opportunities. These factors include high employment, wealth, political stability, better services, and so on.
