Final answer:
Groups of people who are displaced from their homeland and settle elsewhere form a diaspora. Displacement can lead to becoming a refugee, asylum-seeker, or internally displaced person, often caused by conflict, persecution, or environmental disasters. Migration involves the movement of individuals or groups to reestablish a household, often under varied circumstances.
Step-by-step explanation:
Groups of people who are displaced or dispersed from their original homeland and take up permanent residence elsewhere are said to belong to a diaspora. This term relates to the movement and dispersal of large ethnic groups due to reasons such as warfare, institutionalized violence, or opportunity, including education or employment. People who are part of a diaspora maintain ties to their ancestral homeland even as they live in new regions or countries.
Displacement refers specifically to migration caused by more dire circumstances, such as persecution, conflict, or violence, which can result in the status of being a refugee, an asylum-seeker, or an internally displaced person, depending on their situation and location. Environmental migration is another type of displacement, which happens due to natural disasters like earthquakes, hurricanes, or droughts.
On a broader scale, migration includes the movement from one place to another to reestablish a household, which could be temporary or permanent. This broader category can encompass various types of movement, including voluntary and involuntary migration, as well as forced migration, each with its own set of causes and implications.
