It is difficult to provide an exact figure for the "white" population in Mauritania. This is because the concept of "whiteness" is often associated with racial categories that are not widely recognized or used in Mauritania.
Mauritania's population is primarily composed of Black African groups, with a smaller number of Arab and Berber groups. There is a significant amount of mixing between these groups, making it challenging to define a "white" population based on traditional racial classifications.
However, it is important to note that the term "white" can be subjective and can have different interpretations depending on the context. Some individuals might consider certain groups within Mauritania as "white" based on their physical appearance or cultural background.
Ultimately, it is crucial to understand that the concept of "whiteness" is a complex and often problematic one, especially when applied to diverse societies like Mauritania.
