This document discusses migration and refugees. It defines migration as movement between locations, such as from poor to rich states. Millions migrate illegally from the global South to the North for economic, political, educational, or religious reasons or to escape deprivation or displacement. Immigration creates winners and losers as immigrants provide cheap labor but may compete with local workers, though they generally benefit the host economy. States try to limit immigration due to fears over integration and illegal immigration. International law distinguishes migrants seeking economic opportunities from refugees fleeing war, disasters, or persecution who are entitled to asylum or refugee camps. Migration flows occur globally, such as within regions like South Asia or from regions like West Africa to other areas.
