The geographical bias on Wikipedia is an inequality in the distribution of its content with respect to the geographical association of article subjects. It is an element of criticism of Wikipedia, in addition to other biases, such as gender bias, racial bias, or ideological. The research shows that despite considerable differences of this distribution depending on the language of Wikipedia, there is a common trend towards more content related to the United States and Western Europe coupled with the scarcity of information about certain regions in the rest of the world.[1]
