What is the primary reason for migration described as push factors?

Push factors are conditions that drive individuals to leave their home locations, typically due to negative circumstances. These can include factors such as economic hardship, lack of safety, political oppression, environmental disasters, or other unfavorable situations that compel people to seek better living conditions elsewhere.

In this context, the correct answer identifies that negative conditions—such as conflict, poverty, or persecution—are what push individuals to migrate from their established communities. The focus on adverse elements highlights why people might feel compelled to seek new opportunities in different areas where such conditions are absent or less severe.

On the other hand, the other options describe what are known as pull factors. These are attractive elements in a new location that draw individuals in, such as new job opportunities, political stability, or the availability of resources, but they do not explain why someone would leave their current situation.
