Fertility Rate and Mortality Rate, Distinguished
Captions available
The idea
Fertility measures births: crude birth rate is per 1,000 people, general fertility rate is per 1,000 women aged 15–44, total fertility rate is lifetime births per woman; mortality's crude rate is deaths per 1,000 people.
In practice
A region's births and deaths in one year show whether population grows or shrinks.
Where people slip
Fertility and fecundity differ: fecundity is potential births, fertility is actual.
