The book "The Age of Migration" by Stephen Castles and Mark J. Miller, in its second edition, provides an updated overview of global migration and its societal impacts. The authors acknowledge the growing politicization of migration issues, which has led to anti-immigration movements and racist violence in many countries. They discuss significant developments such as the 1993 'asylum compromise' in Germany, changes in France's Nationality Code, and cuts to welfare rights for legal immigrants in the USA. The book also examines new areas of migration, including Eastern Europe, the Arab region, Africa, and Latin America, and the impact of these movements on labor markets and domestic service industries. It highlights the expansion of international cooperation efforts, such as the Schengen Agreement, and the lack of a global agency responsible for observing and coordinating responses to migration. The authors emphasize the increasing polarisation of labor markets and the feminisation of international migration, as well as the ongoing debate on multiculturalism versus assimilation. They conclude that international migration is a major force of social transformation, shaping both sending and receiving societies, and that the age of migration is just beginning.The book "The Age of Migration" by Stephen Castles and Mark J.
