Abstract

このノートは各区の人口に比例して各区に議席を配分する議員定数配分問題を解くことである.人口比例そのものを考察し,1人あたりの議席分布のエントロピーと1議席あたりの人口分布のエントロピーをそれぞれ最大にし,人口と配分議席数が比例する関係とは対称な2項関係であることから,人口に最も比例する配分方式を明らかにする.

This note solves the apportionment problem where legislative seats are allocated in proportion to the population of electoral districts. We define the entropy of the numbers of seats per person (and also the entropy of the numbers of persons per seat) for all districts. By considering the maximization of these two entropies and the symmetry with respect to the number of seats given to each electoral district and the population of the district, we identify an apportionment method as best.
