Why migration

If economic conditions are not favourable and appear to be at risk of declining further, a greater number of individuals will probably migrate to countries with a better outlook. According to the UN International Labour Organization, migrant workers - defined as people who migrate with a view to being employed - stood at roughly million worldwide in and represented nearly two thirds of international migrants.

The environment has always been a driver of migration, as people flee natural disasters, such as floods, hurricanes and earthquakes. However, climate change is expected to exacerbate extreme weather events, meaning more people could be on the move. According to the International Organization for Migration , "Environmental migrants are those who for reason of sudden or progressive changes in the environment that adversely affect their lives or living conditions, are obliged to leave their habitual homes, either temporarily or permanently, and who move either within their country or abroad.

It is hard to estimate how many environmental migrants there are globally due to factors such as population growth, poverty, governance, human security and conflict, which have an impact. Estimates vary from 25 million to one billion by the year Managing migration effectively to deal with asylum seekers and protect external borders has been an EU priority for many years. The new pact is a revision of the Dublin regulation, which determines the country responsible for processing each asylum claim.

Persecution and discrimination based on nationality, race, religion, political beliefs, or membership status in a particular social group [ii] will prompt people to move large distances in search of a safer living location where they can have freedom over their lives.

Danger can be imposed upon individuals by something formal, like war [iv] , or informal, such as widespread gang activity. In , the Northern Triangle, composed of Guatemala, Honduras and El Salvador, was named one of the most violent regions in the world.

All three Northern Triangle countries record thousands of crimes by local and international gangs and armed criminal groups, and most crimes are met with impunity. Economic migration, whether permanent or seasonal, is a commonly cited reason for migration. In general, it is believed that in economic migration people move from poorer developing areas into richer areas where wages are higher and more jobs are available [vi].

It is also common for people from rural areas to move to more competitive urban areas in order to find more opportunities.

Mexican migration [vii] into the United States portrays the importance of both push and pull factors in economic migration. All throughout the 20 th century, seasonal Mexican laborers have crossed the border in search of work in the American agricultural industry, as the economic state of Mexico did not match the level of economic prosperity found in America.

In the 21 st century however, Mexican migration has slowed down significantly, and after the American recession of , economic migration from Mexico to the United States began to decline.
