Final answer:
Civilians who flee conflict within their country without crossing borders are considered internally displaced persons, facing challenges such as loss of property and need for aid.
Step-by-step explanation:
Civilians who flee conflict but choose to remain within their country's borders are considered internally displaced persons. These individuals have fled their homes due to serious threats such as war, persecution, or natural disasters but have not crossed international boundaries. Internally displaced persons are distinguished from refugees, who have been forced to leave their country, and asylum-seekers, whose claims to refugee status are in the process of being reviewed. Despite staying within their home country, internally displaced persons often face significant challenges, including loss of property, lack of access to basic services, and the need for humanitarian assistance.
