厚生労働省から全国的な生命表として公表される平均余命について、ご紹介
いたします。

生命表の分類

厚生労働省から公表される生命表は、簡易生命表と完全生命のふたつに分類
されています。

それぞれの生命表の特徴には、以下のような特徴があります。

簡易生命表

各年10月1日時点における以下の項目をベースとして簡略化された方法
により作成されます。

  • 推計人口
  • 死亡数(概数)
  • 出生数(概数)

完全生命表

5年毎に実施される国勢調査の確定人口および人口動態統計の確定データ
に基づいて、精密に作成されます。

交通事故と平均余命

交通事故による損害算定に当たっては確定数値に基づいた精密な平均余命が
求められことは少なく、簡易生命表が用いられることが多いです。

近年、平均寿命の伸びしろが減少してきていることを理由に、簡易生命表・
簡易生命表のいずれを用いるかの差が生じることはなくなってきています。

実務上は、完全生命表が自賠責保険に採用されていることが多いです。
