In the nineteenth century, the majority of documented migration from other areas of the Americas to the United States was primarily migration from the British colonies in Canada and Newfoundland, as the economic opportunities in the United States were much greater than those to the north. Migration around the turn of the century was slow, as migration from Canada decreased, as well as migration from across the world. Migration from the Americas gradually increased again at the beginning of the twentieth century, peaking in 1924, which saw record numbers of migrants arriving from all three regions. Migration fell again following the Great Depression, however it increased again towards the middle of the century, particularly from Mexico.
