What is the reason for this? Does it have something to do with the fact that the women who don't have any children somehow contribute more to the statistic than women who do have children?
Ygggdrasil said:It accounts for the children who die before they have the chance to reproduce.
No, by definition the fertility rate is the expected number of children of a woman who lives to the end of her reproductive life.swampwiz said:OK, this makes sense - but shouldn't those non-survivors count as simply folks that go childless, and therefore be included in the denominator?
People who don't reproduce still are people, they can't be reasonably considered as nonexistent.swampwiz said:OK, this makes sense - but shouldn't those non-survivors count as simply folks that go childless, and therefore be included in the denominator?
How can you count someone that hasn't survived? (no longer exists.)swampwiz said:OK, this makes sense - but shouldn't those non-survivors count as simply folks that go childless, and therefore be included in the denominator?
The replacement fertility rate of 2.1 is based on the assumption that not all children will reach reproductive age. This accounts for factors such as infant mortality and individuals who may choose not to have children.
The replacement fertility rate of 2.1 represents the number of children a woman needs to have in her lifetime to replace herself and her partner in the population. This is necessary to maintain a stable population size.
The replacement fertility rate is determined using mathematical models that take into account factors such as mortality rates, life expectancy, and fertility patterns. It is also based on observed fertility rates in different populations.
No, the replacement fertility rate has changed over time as societal and environmental factors have influenced fertility patterns. In the past, it was generally lower due to higher mortality rates and the need for larger families for economic and social reasons.
If the replacement fertility rate falls below 2.1, it means that the population is not replacing itself and is expected to decline over time. This can have significant impacts on society, such as an aging population and potential workforce shortages.
