Answer:
poverty
Explanation:
A push factor is a factor that is making the people to migrate away from a certain place. These factors are numerous, but one of the most common is the poverty. The poverty is a big push factor, as no one wants to be poor and to be barely able to survive, but instead everyone wants decent and better life standard. Considering the amount of poor people in the world, it is no wonder that this push factor is resulting in large scale migration from the poor nations around the world, toward the more developed nations, so that the people can escape the poverty and have much better living conditions.
