Overall patterns in migration and urbanization can be observed. There is however a lack of empirical data and the absence of systematically collected information of a comparative quality and content, especially in low income countries. This lack of data inhibits a deep understanding of migrants in urban environments. Cities, with their high concentration of migrants, often from different places of origin, offer a unique spatial domain for researching and understanding the dynamics of migration, urbanization and the intersection of national and local governance and policy.
