日本の各種統計データの可視化 (人口・国土)

1.概要

「Google Chartsを使ってデータの可視化」で各種グラフパターン のテンプレートを作成しましたが、実際のデータでないとピンとこないので、今回は、その第一弾として、日本の人口や国土(面積など)のデータを 利用してグラフパータンに当て嵌めて見ました。グラフによる可視化で全体の把握や相互の比較ができて分かりやすくなったと思います。 文字や表だけのデータでは味気ないですね。グラフは作っている途中で眺めていても楽しいものです。


2.利用方法

グラフは下記の14種類を作成しました。下記のデモ(DEMO)日本の各種統計データの可視化 (人口・国土)をクリックすると実際のグラフが確認できます。

・ 1. 全国人口の推移－総人口
・ 2. 全国人口の推移－日本人人口
・ 3. 総人口男女別割合
・ 4. 日本人人口男女別割合
・ 5. 年齢階級別(総人口－男)
・ 6. 年齢階級別(総人口－女)
・ 7. 年齢階級別(日本人人口－男)
・ 8. 年齢階級別(日本人人口－女)
・ 9. 地域別の面積 (2020年)
・10.地域別の面積割合（2020年)
・11.都道府県別の面積（2020年)
・12.面積の広い島（2020年) ※本島を除く
・13.面積の広い島（2020年) ※本島とその他
・14.面積の広い島（2020年) (割合)
