To maintain a stable population, a nation's fertility rate should be at or near the replacement level, typically estimated at about 2.1 children per woman. This rate accounts for the number of children needed to replace the parents, considering factors like infant mortality. If the fertility rate falls significantly below this level, the population may decline over time, while rates significantly above it can lead to rapid population growth.
What else can I help you with?
With a fertility rate of 2.1 a developed country would be considered stable growing shrinking or endangered?
A fertility rate of 2.1 children is considered stable excluding migration flows.
Which nations would you expect to be concerned about declining population?
Nations with aging populations and declining fertility rates, such as Japan, Germany, Italy, and South Korea, would likely be concerned about declining population. These countries may face issues related to workforce shortages, economic stagnation, rising dependency ratios, and strains on social security and healthcare systems.
What will happen to population levels of TFRs become the same as the RR?
If total fertility rates (TFRs) become the same as replacement rates (RR), population levels would stabilize over time, assuming no significant changes in mortality or migration rates. This means each generation would be producing enough offspring to replace itself, leading to a balanced population size. However, the long-term effects would depend on age distribution and other demographic factors, as a stable birth rate does not necessarily guarantee a stable population if there are shifts in life expectancy or migration patterns.
Is it a stable population if it changes from year to year?
Stable reflect variation.We can use terms of being:Very stable, less stable, not so stable.At the same time in same but inverse order:A little variation, more variation, most variation.A stable population would be considered a population that does not vary in numbers that much. Fluctuation is considered normal. Stability of a population is its stability over time as in several generations.An unstable population would go drastically up or down within few generations.We do not count a population as stable the same way as we would categorise an element to be stable. A population is allowed to vary slightly over time, where as an element that vary slightly over the same time might be called unstable.Other factors are to be considered:If a population is very high as in numbers of older not propagating specimens then it could be considered an unstable population because it would be unable to sustain its numbers and diminish over time.If a population lives under conditions unsuitable for sustaining quality of life then it would affect its stability.More factors will apply.Stability is statistics. We can make statistics to suit our present needs even if the numbers does not lie.
Where would you expect to find in a country with zero population growth?
In a country with zero population growth, you would expect to find a stable population size where the number of births equals the number of deaths. This would mean the population is not increasing or decreasing over time.
If the birth rate equals the death rate then the is what?
The overall growth rate of the general population is stagnant .
Assuming that other factors are equal how are the immigration and emigration rates related in a stable population?
In a stable population, where births and deaths are roughly balanced, immigration and emigration rates would also be roughly balanced. This is because the population is neither growing nor declining, so the number of people entering the population through immigration would be offset by the number leaving through emigration.
When this is high the population increases?
There may be many different answers for this question, but the most obvious would seem to be that population increases when birth rates are high. Similarly, in countries where fertility rates are high then population is very likely to increase.
What is The state of a population where the number of births plus immigrants equals the number of deaths plus emigrants?
That would be called a "stable" or "static" population - essentially unchanging.
If over a per of ten years a population has a logistic growth rate you would expect to see?
A stable equilibrium phase
What would happen to fertility of a soil if all decomposers were removed?
if all the decomposers were removed the fertility would wouldnt grow :)
What would happen to the fertility of a soil of all decomposers were removed?
if all the decomposers were removed the fertility would wouldnt grow :)
