The annual per capita GDP in an MDC (More Developed Country) is 270,000, while in an LDC (Less Developed Country) it is 4000. This means that the average income per person in an MDC is significantly higher than in an LDC. MDCs generally have more advanced economies, higher levels of industrialization, and better infrastructure, which contribute to their higher per capita GDP. On the other hand, LDCs often face challenges such as poverty, limited access to education and healthcare, and underdeveloped economic sectors, resulting in lower per capita GDP.
