This is the age of migration. There have, of course, been times of great population flow: the mass movements at the end of World War II, or the early years of the 20th century, when the populations of US cities began to surge. Others would point to the move across the Western United States, or further back to the age of colonialism and exploration by Europe.
But I firmly contend that migration, as it exists right now, is the mega-trend of our times, and is ineffably changing the world as we know and experience it.
