Which of the following is a push factor in migration?

A push factor in migration refers to circumstances that drive people away from their current location. Natural disasters exemplify this concept perfectly, as they can create unsafe living conditions, destroy homes, and disrupt normal life activities. When individuals or families experience events such as earthquakes, floods, or hurricanes, they often feel compelled to leave their area to seek safety, stability, and basic necessities elsewhere.

In contrast, the other options represent pull factors that attract people to new locations. Job opportunities in another country draw people towards locations promising employment. A low cost of living can be appealing, as it often signifies a better standard of living in a different area. Similarly, access to healthcare attracts individuals who prioritize their health and that of their families. Each of these factors indicates a positive aspect of a new location rather than a negative condition in the current one, thus distinguishing them from push factors like natural disasters.
