ABSTRACT
Until lately, economic nationalism had not interfered greatly with immigration (apart from Oriental immigration). After the war the great migration movement began to ebb. Ethnical conceptions came to the forefront; immigration policies were no longer directed by economic considerations. The making of a new nation was becoming a “synthetic” process, for which the proper choosing of the constituent elements—by limitation of alien admixtures—was essential. The U.S.A. restricted oversea immigration quantitatively and qualitatively by fixing a quota of 150,000 a year. Most new countries followed their example in some form or other; some of the Dominions interrupted migration even from the mother country.
