How many children should each woman have to do no more than replace herself and her mate (assuming one mate)?
As a global average, she should have about 2.1 children. The number is slightly higher than two to account for infant mortality.
Reproduction at this level is calledreplacement level fertility ("RLF")

What is population replacement level?
Population replacement level refers to the fertility rate needed for a population to replace itself without migration, typically around 2.1 children per woman. This rate ensures the current population size is maintained over time. A fertility rate below the replacement level can lead to a declining population and various social and economic challenges.

What is a replacement level (In geography)?
In geography, replacement level refers to the fertility rate at which a population exactly replaces itself from one generation to the next, without migration. This level is typically estimated to be around 2.1 children per woman in developed countries, accounting for infant mortality and other factors. When a population is at replacement level, its size remains stable over time, assuming no significant changes in migration patterns.
What is meant by population momentum and what is its cause?
Population momentum refers to population growth at the national level which would occur even if levels of childbearing immediate declined to replacement level. Replacement level- replace the husband and wife with two children so when the parents both die the children will take their place in the population. The cause of this is fertility rates
What exactly does a fertility monitor do?
Fertility monitors test the level of LH or luteinizing hormone in the urine. An increase in the level of this hormone indicates that the ovaries are about to release an egg. Using a fertility monitor may increase a woman's chances of conceiving.
How do the population profile and fertility rates of developed countries differ from those of developing countries?
Developed countries typically have older population profiles with lower fertility rates, often below the replacement level of 2.1 children per woman, due to factors such as increased access to education, family planning, and economic opportunities for women. In contrast, developing countries generally have younger populations and higher fertility rates, often exceeding replacement levels, driven by limited access to education and healthcare, cultural norms favoring larger families, and higher child mortality rates. These differences contribute to varying demographic challenges and economic growth potentials in each group of countries.
Can a woman have a baby after menopause?
Yes, with the help of fertility drugs (replacement hormones) and donor eggs it is very possible for a woman to have a baby years after menopause.
Are silt deposits usefull as soil replacement?
Many farming areas in the world depend on silt deposited during floods to replenish the fertility in their soil. RB
What is the pH level of oil?
The pH leve of soil depends upon it's fertility. If the soil is used to fertilizers or pesticides, it becomes acidic, loses it's fertility and pH level goes down.
Define demographic momentum?
Demographic momentum is the idea that a population will continue growing long after replacement fertility has been reached. Replacement fertility means that women are averaging 2.1 children each. Demographic momentum happens because of a large fraction of it's population entering their reproductive years.
How can I determine my fertility status and find out if I'm fertile"?
To determine your fertility status and find out if you're fertile, you can consult a healthcare provider for a fertility evaluation. This may include tests such as hormone level checks, ovulation tracking, and semen analysis for males. Additionally, discussing your medical history and lifestyle factors with a healthcare provider can help assess your fertility potential.
