...When calculating how many children a group of girls born in a certain year will give birth to in their lifetime, or the death rate of the population born in a certain year, this is called the fertility or mortality rate (or survival rate) of an "actual cohort." However, when considering how many children a group of women born in a certain year will give birth to in their lifetime, given their age-specific fertility rate (the fertility rate of multiple cohorts), these cohorts are called "hypothetical cohorts." Life tables also use this concept. *Some of the terminology used to refer to "hypothetical cohort" is listed below. Source | Heibonsha World Encyclopedia 2nd Edition | Information |
…ある年次に生まれた出生女児集団が一生涯にどのくらいの子どもを産んだか,またある年次の出生の人口がどのような死亡率で死亡していったかを計算する場合,これを〈実際コーホートactual cohort〉の出生力とか死亡率(あるいは生残率)とよばれる。しかし,ある年次の年齢別の女子人口の特殊出生率(多数のコーホートの出生率)をもって,生涯を経過している間にどのくらいの出生児を産むことになるかを考えた場合,これらのコーホートを〈仮設コーホートhypothetical cohort〉という。生命表もこの概念を利用したものである。… ※「hypothetical cohort」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
