Causes of Migration
We can divide factors causing migrations into two groups of factors as push and pull factors.
Push and Pull factors
Push and pull factors are those factors that either forcefully push people into migration or attract them. A push factor is forceful, and a factor that relates to the country from which a person migrates.
A pull factor is something concerning the country to which a person migrates. It is generally a benefit that attracts people to a certain place. Push and Pull factors are usually considered as north and south poles on a magnet.

Overpopulation is the state whereby the human population rises to an extent exceeding the carrying capacity of the ecological setting. In an overpopulated environment, the number of people might be more than the available essential materials for survival such as transport, water, shelter, food, or social amenities.
This regularly contributes to environmental deterioration, worsening in the quality of life, or even the disintegration of the population. Due to immigration, the decline in mortality rates, medical breakthroughs, and increased birth rates, populations will always increase and eventually gives rise to overpopulation.
