According to world systems theory, Mexico is a semi-periphery country, which means it is an industrializing, mostly capitalist country positioned between the periphery and the core countries. In this case, it lies between the United States and the rest of Latin America.
It is also not part of the core countries (US, Canada, Western Europe, Japan) and it is not part of the periphery or less developed countries (most of Africa, South America or Southeast Asia).
It is a gateway or semi-periphery country because it acts as a bridge or link between both worlds.
Periphery
I think it is a core country.
The largest country in land area within the eastern periphery region is Russia. With its vast expanse stretching from Eastern Europe to Northern Asia, Russia covers a significant portion of the eastern periphery region.
An example of a periphery country is Honduras in Central America. It is characterized by its economic dependence on more developed countries, limited industrialization, and reliance on agriculture for export earnings. Periphery countries often face challenges such as high levels of poverty and limited access to resources and technology.
Most people living in the Mexico City proper are born within Mexico City; there are some immigrants from central and southern states but most of them tend to live on the periphery, on greater Mexico City.
Think of it like this: The core are the exploiters and the periphery are the exploited. It's almost as if the core is a highly developed country, and the periphery is the less developed country in the space around it.
There are no countries in Mexico, Mexico is a country.
Sclera on the outer periphery and vitreous fluid on the inner periphery.
Core-periphery theory is the relationship between 2 countries, with the core being more developed while the periphery being the less developed. Usually, the core would benefit while the periphery would remain undeveloped because things like labour and raw materials travel from the periphery to the core.
