This document discusses different types of migration including international and internal migration. International migration can be voluntary or involuntary. Internal migration includes rural-urban, seasonal, and planned migration within a country. International migration can have socio-economic, cultural, and political impacts on both the host and source countries. Socio-economic impacts include brain drain and challenges with social assimilation. Cultural impacts depend on the colonial history and ethnic composition of an area. Politically, immigrants may vote for parties that support their needs. Migration also affects the economies, societies, and cultures of both the host and source countries through impacts like remittances, changing family structures, pressure on resources, and the creation of multiethnic societies.
