最近実人口カバー率がどうとか言う話が増えて、昔ながらの人口カバー率について人口カバーと面積カバーの関係と言うのを作ったのがあまり役立たずになっちゃってる感じなので、実人口カバー率について、同じような分析をしてみました。

ネタは簡単で、国勢調査の500mメッシュデータを並べて、データにしただけです。しただけですと言いつつ、データ量が超多いのでめんどくさかったのですが。

で、このデータを作って気が付いたというか思い出したのですが、日本って、総面積の3割くらいしか人が住んでないんですね。ってことで、総面積に対する比率だとよくわからなくなるので、「人が住んでる面積に対する比率」を「実面積カバー率」と定義して、データを作成。

まずグラフ。

旧人口カバーと傾向はほぼ同じ。

次に、人口カバー率に対しての順引き・逆引き一覧表。
