Total Fertility and the 2.1 Line
Captions available
The idea
The total fertility rate is the average number of children a woman would bear over her lifetime. Replacement level is the fertility that lets a population replace itself, roughly two point one. Below it, a population eventually shrinks without migration.
In practice
A cohort: a subset defined by age.
Where people slip
The anchor says roughly two point one.
