With European colonization and migration, positive aspects of European culture spread across the globe in spite of obstacles.

In the process known as step migration, migrants move from rural to urban areas through a series of smaller moves, or steps.

Each migration produces a counter migration of people returning to their country of origin.

The gravity model predicts that most migrants will move to the closest large metropolitan area in search of economic opportunities.

Migrants leave their homelands because of push factors and move to places with pull factors, but they often face barriers as they migrate.
