Migration is the demographic process that links rural to urban areas, generating or spurring the growth of cities. The resultant urbanization is linked to a variety of policy issues, spanning demographic, economic, and environmental concerns. Growing cities are often seen as the agents of environmental degradation. Urbanization can place stress on the land through sprawl; coincident industrial development may threaten air and water quality. In the eyes of many observers, rapid urbanization is also linked to problems of unemployment and the social adaptation of migrants in their new urban setting. Cities advertise society's inequalities in income, housing, and other social resources, whether these problems are new or just newly manifest in urban settings.

Most of the migration conventionally liked to these urban issues was seen as following a conventional pattern. In this policy brief I raise some issues about the nature of contemporary, migratory behavior, both for our understanding of processes of population redistribution directly, and for understanding some of the implications of that redistribution. Contemporary research is sketching the contours of this migratory behavior and the social adjustment that accompanies it. New research is beginning to shed light on the rate of migrant adaptation, on the connection between origin and destination communities through remittances, and the demographic structure and dynamics of refugee movements.

The New Migration?

Is there an evolving pattern of migratory behavior and composition that warrants a reconsideration of our prevailing models? The first round of migration models presumed that movement -- permanent movement -- was induced by prevailing wage differentials and economic opportunities. Thus one observed transatlantic migration from Old to New World as part of a permanent population redistribution within and across generations. To be sure the emptying of the countryside in the 19th century made London, Paris and New York into huge urban agglomerations.
