Abstract

This work aims to redesign the large regions of Brazil based on agglomerations of municipalities with similar socioeconomic characteristics. Based on data from the last two censuses, 2000 and 2010, a matrix of 41 socioeconomic variables was selected for each one of the Brazilian municipalities. Then, the size of this matrix was reduced using the principal component analysis (PCA) method. The main components were selected to compose the algorithm of hierarchical agglomeration that defined the municipal clusters. The results of the agglomeration indicated the existence of eleven regions of municipalities for the year 2000 and ten regions for the year 2010, showing that the current political‐administrative map of the regions does not represent the junction of cities that maintain a relation of homogeneity. Este trabajo tiene como objetivo rediseñar las grandes regiones de Brasil a partir de aglomeraciones de municipios con características socioeconómicas similares. Con base en los datos de los dos últimos censos, 2000 y 2010, se seleccionó una matriz de 41 variables socioeconómicas para cada uno de los municipios brasileños. A continuación, se redujo el tamaño de esta matriz mediante el método de análisis de componentes principales (ACP). Los componentes principales fueron seleccionados para formar el algoritmo de aglomeración jerárquica que definió los conglomerados (clusters) municipales. Los resultados de la aglomeración indicaron la existencia de once regiones de municipios para el año 2000 y diez regiones para el año 2010, lo cual muestra que el mapa político‐administrativo actual de las regiones no representa la confluencia de ciudades que mantienen una relación de homogeneidad. 本稿では、ブラジルの5つの地域を、社会経済的な特性が似ている自治体の集積度に基づいて再編することを目的する。2000年および2010年の、最近の2回の国勢調査のデータに基づき、41の社会経済変数の行列を自治体ごとに選択した。次に、主成分分析を用いて行列のサイズを縮小した。自治体のクラスターを定義する階層的集積のアルゴリズムを構成する主要な要素を選択した。集積の結果から、2000年には地方自治体の11の地域、2010年には10の地域の存在が示され、現在の行政区域の地図は、同質性による関連を維持する都市のつながりを表すものではないことが示された。
