Factors that contribute to persons becoming refugee

There are several factors that may lead to people becoming refugees, including warfare, political instability and natural disasters such as floods, tsunamis and famines. Refugees are defined as people who must leave their homes or native areas for reasons of safety and survival. Natural and man-made disasters can cause large segments of the population to flee from their native states, regions and countries into neighboring territories to wait temporarily until it is safe to move back home, or relocate for good.
