...Comparing 1950 and 1980, the population in Southern Kanto increased from 15.5% to 24.5%, while the population in Tohoku and Kyushu/Okinawa dropped significantly from 10.7% to 8.2% and 15.5% to 12.0%, respectively. Methods for expressing population distribution include population density, center of population (the position of the point that horizontally supports the entire region when the region is considered as a plane and the weight of each person distributed there is assumed to be the same), population potential (the result of expressing the state of population distribution based on physical concepts, assuming that it has some kind of energy that influences each other), and Gini coefficient. In addition, population distribution is divided into regions based on the characteristics of the region, such as urban, rural, and urban areas. *Some terminology explanations that mention "population potential" are listed below.

…1950年と80年を比較して,南関東が15.5%→24.5%へと増大しているのに対し,東北10.7%→8.2%,九州・沖縄15.5%→12.0%へと著しい減少を示している。このような人口分布の状態を表す方法としては,人口密度,人口重心center of population(当該地域を平面と考え,そこに分布する個々の人間の重さを同じと仮定した場合に,この地域全体を水平に支える点の位置),人口ポテンシャルpopulation potential(人口分布が相互になんらかの影響を与えるエネルギーをもつと想定し,その状態を物理的概念に基づいて表現した結果),ジニ係数等がある。また,都市,農村,都市圏といった地域の特性による人口分布の地域区分が行われる。… ※「population potential」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
