What is the poorest nation in the world?

Excuse me, could you possibly enlighten me on a matter? I am quite intrigued by the subject of global economics and statistics, and I have a particular question that has been puzzling me for quite some time. I was wondering, based on current available data and statistics, what would be considered the poorest nation in the world? I realize that this question might be quite complex, considering various factors such as GDP, poverty rates, and infrastructure development. However, I am quite curious to understand which country, or perhaps region, would rank the lowest in terms of overall economic well-being. Thank you for your time, and I appreciate any insights or perspectives you might have on this matter.
