which is a set of push and pull factors tied ...

# Brief Explanations: Push factors drive people out of an area (like famine), and pull factors attract people to an area (like jobs). Famine creates a need to leave, and jobs offer an incentive to move to a new place. War and peace are more about general conditions rather than direct push - pull related to economic or survival needs for migration.
