Human migration
Human migration is the movement of people from one place to another with intentions of settling, permanently or temporarily, at a new location (geographic region).The movement often occurs over long distances and from one country to another (external migration), but internal migration (within a single country) is the dominant form of human migration globally.Migration is often associated with better human capital at both individual and household level, and with better access to migration networks, facilitating a possible second move. It has a high potential to improve human development, and some studies confirm that migration is the most direct route out of poverty.Age is also important for both work and non-work migration.People may migrate as individuals, in family units or in large groups. There are four major forms of migration: invasion, conquest, colonization and emigration/immigration.People moving from their home due to forced displacement (such as a natural disaster or civil disturbance) may be described as displaced persons or, if remaining in the home country, internally-displaced persons. People who flee to a different country due to political, religious, or other types of persecution in their home country can formally request shelter in the host country. These people are commonly referred to as an asylum seekers.
