I looked at economic data for 2025, and the list of the world's poorest countries is indeed concentrated in Sub-Saharan Africa and parts of Asia. South Sudan ranks last with a per capita GDP of only $251, followed by Yemen at $417 and Burundi at $490. African countries make up the vast majority, and this phenomenon actually reflects long-term development disparities.

Interestingly, within the regions listed as the world's poorest countries, some differences can also be observed. Although India has a large population, its per capita GDP is only $2,878, which shows how big the wealth gap is. Countries like Lesotho and Uganda, while ranking lower, are already better off compared to the poorest few countries.

This data reminds us that there is still a huge gap in global economic development. These countries face not only income issues but also challenges in infrastructure, education, healthcare, and other areas.
