To understand migration flows from one poor country to another,
it is not sufficient to analyze the flow at the global scale. 

We need to understand where the region fits into the global interaction picture
and to see how different locations within the region fit into interaction patterns at both the global and regional scales. 

Cities in the developing world are typically where most foreign investment goes,
where the vast majority of paying jobs are located, and where infrastructure is concentrated. 

These port cities become islands of economic development within larger undeveloped regions. 

Geographers call these cities islands of development (Fig. 3.12).

Within the region of West Africa, the oil-producing areas of Nigeria are islands of development.
In the mid-1970s, poorer people in Togo, Benin, Ghana, and the northern regions of Nigeria,
perceiving that economic life was better in coastal Nigeria,
were lured to the coast for short-term jobs while the oil economy was good. 

The migrants, usually young men, worked as much as they could and sent almost all of the money 
they earned home as remittances to support their families. 

They worked until the oil economy took a fall in the early 1980s,
and at that point, the Nigerian government decided the foreign workers were no longer needed. 

The Nigerian government forcibly pushed out 2 million foreign workers.

Global economic processes and the lasting effects of European colonialism certainly played a role in this West African migration flow. 

If we study such a fl ow only at the global scale, we see migrants moving from one poor country to another poor country. 

But if we use both the global and regional scales to study this flow,
we understand regional economic influences and the pull of islands of development in Nigeria.
