What is the term for migration that is usually prompted by a threat to one's safety, such as war or disaster?

The term that describes migration often prompted by a threat to one's safety, such as war or disaster, is indeed forced migration. This type of migration occurs when individuals are compelled to leave their homes against their will due to urgent or dangerous circumstances. Examples include refugees fleeing armed conflict or people evacuating an area affected by natural disasters.

In contrast, voluntary migration refers to the movement of individuals based on personal choices, such as pursuing job opportunities or better living conditions. Internal migration involves the movement of people within a country, often related to economic factors rather than life-threatening situations. Pro-natalist migration is not a widely recognized term in migration studies, but it generally refers to policies aimed at encouraging higher birth rates rather than addressing issues related to safety or conflict.

Understanding the specific motivations and circumstances behind forced migration highlights important humanitarian and geopolitical concerns that impact global populations today.
