Completed fertility

From Demography
Jump to: navigation, search
This article describes a measure that can be evaluated for a particular individual person, household, or family. It is not a statistical aggregate, though it may be statistically aggregated to provide average measures and distributions.
The measure is a lifetime constant, i.e., it does not vary with time.
The measure is not subjective, as the measurement of its value is not based on people's beliefs, opinions, and/or values. Note that the actual value itself is influenced by people's decisions, and hence by their subjective preferences, but the measurement of these values is not.

Definition

The completed fertility of a particular female who has completed her childbearing years will not have any more children is the number of children the female has had (here, a "child" is counted as a live birth by the female). Completed fertility is a particular form of female fertility that applies only to females who can no longer have children.

In practice, a fixed age range (such as 15-44 or 15-49) is used as a proxy for childbearing years.
