The paper presents the problem of choosing the representatives in an assembly when the whole electoral region is subdivided into electoral districts. Because of the two dimensions, geographical (districts) and political (parties), the problem is called bi-apportionment. The main focus of the paper is to discuss fairness and proportionality axioms as well as their implementation.
