Final answer:
Mexico's classification as a developing country is influenced by its semi-periphery status and the challenges it faces in terms of limited resources and financing development.
Step-by-step explanation:
One factor that helps classify Mexico as a developing country is its semi-periphery status. Mexico is industrializing and positioned between a core and a periphery country. This means that while Mexico has made progress in industrial development, it still faces challenges such as limited resources, political obstacles, and a lack of large sums of money for financing development.
