A World Without Borders
The internal migration occurred majorly between rural and urban areas. Due to the rapid urbanization, more people from rural areas moved to the urban regions. The urban regions provided more jobs and better pay for the people. The regions also had a lot of resources helpful to the people who migrated to the urban areas.
The occurrence of a government change increases the likelihood of subsequent changes. Political instability tends to be persistent. The uncertainty associated with an unstable political environment may reduce investment and the pace of economic development.
The most Highly Urbanized Societies
The most highly urbanized societies are in big cities like Tokyo, Mexico City, New York and other majorly populated and metropolitan cities.
The Challenging Transformation
With the onset of the agricultural and industrial revolution in the late 18th century this relationship was finally broken and an unprecedented growth in urban population took place over the course of the 19th century, both through continued migration from the countryside and due to the tremendous demographic expansion that occurred at that time.
In cities like Bombay, Mexico City and Buenos Aires face problems because of the thousands of people crammed into a small area. The resources the city can provide for its people is limited, causing there to be a lot of poverty and starvation. Issues like this grow in those cities as the population keeps increasing.
Voluntary and Forced Migrations
During the Afghanistan war, thousands of Afghan refugees left their land to escape the ravages of the war and went to other lands. This was forced migration because they had nowhere to live and were required to migrate in order to find shelter, food and a job to support themselves and their family. Minorities like this would travel very often.
Xenophobia is the fear of foreigners. This fear was and is an effect of migration. The migration of millions of foreigners into certain lands caused resources to be used faster, and the people already habituated in the region were distressed by that. This led to violence as the people wanted to eliminate the foreigners, fearing them.
