# What does poorest country by population mean?

I understand poorest countries based on GDP but what does poorest countries by population mean? Below is the link to the information I was looking at. http://worldpopulationreview.com/countries/poorest-countries-in-africa/

• The measure used seems to be GDP divided by population (i.e. per capita) – Henry Aug 14 '19 at 19:58

$$\text{GDP Per Capita}=\frac{\text{GDP}}{\text{population}}.$$
