A growing realization on the part of scholars and the general public has been the increasing interdependence of the world. Technology and communications have narrowed distance and time between diverse cultures, resulting in increased contact, if not increased cultural harmony.
The immigration of millions of persons to new homes has heightened this interdependence. In the Western Hemisphere not only the United States but also Mexico, Brazil, Argentina, and Chile received substantial numbers of immigrants.
Brazil, alone, was the recipient of more than 5 million immigrants. The majority of the immigrants, apart from those of the Iberian Peninsula, came from Germany, Italy, and Japan. Chronologically, the Germans arrived first, the Italians second, and the Japanese third. Numerically, Italy has contributed 1.5 million, Germany 300,000, and Japan 170,000 to date.
