Periphery countries are nations that are less developed economically and politically compared to core countries. They often rely on agriculture and raw material exports, facing challenges like poverty, limited industrialization, and political instability. Examples of periphery countries include Bangladesh, Haiti, and Ethiopia. These countries are often situated on the outskirts of the global economy, which is dominated by core countries like the United States and Germany. Periphery countries may benefit from foreign investment and trade, but they frequently struggle with issues such as inadequate infrastructure and education, which hinder their development.
