Most settlers who came to America in the 17th century were English, but there were also Dutch, Swedes and Germans in the middle region, a few French Huguenots in South Carolina and elsewhere, slaves from Africa, primarily in the South, and a scattering of Spaniards, Italians and Portuguese throughout the colonies.
After 1680 England ceased to be the chief source of immigration. Thousands of refugees fled continental Europe to escape the path of war. Many left their homelands to avoid the poverty induced by government oppression and absentee-landlordism.
By 1690 the American population had risen to a quarter of a million. From then on, it doubled every 25 years until, in 1775, it numbered more than 2.5 million.
Although a family could move from Massachusetts to Virginia or from South Carolina to Pennsylvania, without major readjustment, distinctions between individual colonies were marked. They were even more so between the three regional groupings of colonies.
