Completed cohort fertility
The completed cohort fertility (CCF), also called the completed fertility rate (CFR) for a cohort of females (typically, a birth cohort) who have all completed their childbearing years is the arithmetic mean of the values of completed fertility for all females in that cohort.
For a given birth order
Completed fertility rates can be computed only for cohorts that have completed their childbearing years. This creates a huge time lag: we can only calculate completed fertility rates for cohorts that were born 49 or more years ago.
Some sources, such as the Human Fertility Database, provide a piece of information called CCF40: this is the parity at age 40 for the cohort. This may also be broken down by birth order.
