サムネイル|年齢中央値の国別地図 CIA World Factbook, 2016年推計 国別の年齢中央値リスト（くにべつのねんれいちゅうおうちリスト、List_of_countries_by_median_age）は、国別に表した年齢中央値リストである。
概説 年齢中央値とは、全人口を、その年齢より若い年齢層と、その年齢より高い年齢層の2つの数値的に等しい年齢層に分ける指数である。人口の年齢分布に関連する唯一の指数である。
現在、年齢中央値は、ほとんどの後発開発途上国での18歳以下という低いものから、ほとんどのヨーロッパ諸国、カナダ、日本、台湾、キューバ、韓国で40歳以上という幅がある。女性の年齢の中央値は、旧ソビエト連邦諸国の一部では男性よりもはるかに高い傾向があるが、グローバル・サウスでは、その差ははるかに小さいか、逆転している。
この記事では、中央情報局（CIA）と国連（UN）の推計に基づく2つのデータを提供する。
