First published in 1885, Ernst Ravenstein's Laws of Migration includes a theory highlighting the inverse relationship between the distance and volume of migration between a source and destination.  Ravenstein's work still forms the basis of modern human migration theory.

This type of gradual migration, from farm to village to town to big city, is known as a “step migration” because it happens in a series of steps. It is a common way by which rural families arrive in an urban setting.

Migrants do tend to relocate after they have reached their desired destination. It is also common for migrants to return to their original location. All of the other statements are true.

Internal migration involves movement within a nation-state (e.g., the United States). Mikey's movement from New York to New Hampshire is a good example of internal migration.

"Mobility" is the ability of something or someone to move from one place or region to another. "Migration" refers specifically to groups of people or animals moving from one region or country to another. "Travel" is voluntary movement from one region to another.

Hearth, relocation, expansion, hierarchical, contagious, and stimulus are all different types of diffusion.

Great Britain's North American Colonies saw a wide variety of people take the opportunity to settle America's Atlantic coast. Due to the wide variety of colonies and locations from which people came, the reasons for traveling to the New World ran the gamut from political and religious reasons to simple economic necessity and serving punishment in the colonies. Almost all of the colonists were middle or lower class individuals seeking a better life, rather than individuals trying to get rich quickly.

The Pilgrims who migrated to America in the early seventeenth century did so in order to escape religious persecution in Europe. They were motivated by reasons of political repression and a desire for personal freedom.

In the early years of the American republic, white settlers and the native population clashed violently and frequently, often resulting in massacres and atrocities (more frequently, but not exclusively, committed by white settlers). In 1830, the American government passed the Indian Removal Act, which forced a large number of Native Americans (most of whom were living in the South) to migrate west of the Mississippi. The subsequent death march is referred to as the Trail of Tears. This took place during the Presidency of Andrew Jackson.

Brazil and the Caribbean were by far the most common destinations for enslaved Africans during the era of the Atlantic Slave Trade. This is because the climates of Brazil and the Caribbean were perfect for growing all sorts of different plantation-based cash crops like sugar, rubber, and cotton.
