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.

Pull factors include higher wages, better employment opportunities, a higher standard of living and educational opportunities. 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.
