Although potential migrants comprise perhaps 50 percent of the world's population, only 2 percent of people actually move from their birthplace to live elsewhere on the planet; one half of these move from one less economically prosperous nation to another. On the other hand, so many people move from just a few places: about 65 million people have moved from poorer nations in the global South to wealthier nations north of the equator (one-third of these end up in only six countries), and that number is dwarfed by the South–South movers. Each is likely to live lives increasingly described as transnational, neither time-specific (i.e. pre- or post-migration only) nor nation-centered (i.e. focused only “back home” or in the “new home”); instead, their lives are centered in communities that operate as if the passage of time is benign, and national boundaries porous. Faist 2000 asks why so many move from so few places, and how they make and keep transnational ties; he finds social networks are keys to the answers.
