Final answer:
Groups displaced from their homeland and settling elsewhere are part of a diaspora population, driven by factors like conflict, opportunity or environmental disasters, and understanding these movements is vital to population studies.
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 population. This can occur due to a variety of reasons such as warfare, institutionalized violence, or pursuit of opportunity through education or employment. When people are displaced due to persecution, conflict, or violence, it involves refugees and those seeking asylum. This is known as forced migration or displacement. Moreover, environmental migration occurs when individuals are displaced due to natural disasters like earthquakes, hurricanes, or droughts. Understanding these movements is crucial when studying populations and their dynamics, including migration, which can be voluntary, involuntary, or forced.
