Push factors are reasons to leave a place.

Explanation:

Push factors are the factors that result in immigration. These factors are negative ones, or to put in other words, they are the reasons why people leave a place and move toward another better one. The push factors can cause the migration of people that is small, gradual, sudden, or on large scale.

This type of factor can be related to a lot of things, ranging from politics, economic reasons, lack of opportunities, to war, famine, oppression, etc. As mentioned, some of these reasons can result in a small scale or gradual migration, like politics and economics, like is the case in the Balkan Peninsula. On the other hand, some of these reasons, like war and famine cause sudden and large scale migration of people, which is hard to handle, and good examples of this are Syria and Somalia.
