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.
What is natural decrease?
Natural decrease refers to the situation where the number of deaths in a population exceeds the number of births over a specific period. This phenomenon often leads to a decline in population size and can result from factors such as low birth rates, high mortality rates, or an aging population. Natural decrease is an important demographic trend that can impact economic growth, social services, and community sustainability.
Formula of death Rate?
usually birth and death rates are calculated based on 1000 people, not per capita (1 people), because per capita rates are very small. Nonetheless, both per capita rates are calculated by simply dividing the total number of births (or deaths) by the total population. The total population should be the one at the beginning of a specified period (or, better, an average for the entire period) whereas the births /deaths are counted for the entire period. For example, China had an estimated population of 1,300,000,000 in January 2005. In the whole year 2005 about 17,100,000 births were expected. This corresponds to a per capita birth rate of 17.1 mio./1300 mio. = 0.01315 Similarly China's per capita death rate can be estimated to be about 0.00694, which means the Chinese population is growing overall.
Replacement rate the number of births needed to keep a population at a stable level without immigration requires a total fertility of?
2.1
How does the definition of deathrate and birthrate differ?
Birth rate means the number of births per thousand persons in a particular year and at a particular area.Death rate means the number of deaths per thousand persons in a particular year and at a particular area.
What does natural change mean?
Natural change refers to changes that occur in a population due to factors such as births and deaths, without the influence of migration. It is calculated by subtracting the number of deaths from the number of births in a given population over a specified period of time.
What does zero population mean?
Zero population means that there is no growth in the number of people or animals or plants in an area. The number of deaths equal the number of births.
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.
Calculate the natural increase in a country?
To calculate the natural increase of a population, you take the the countries' birth rate (number of live births per 1000 population per year) minus the countries' death rate (number of deaths per 1000 population per year) -- BR-DR
The number of births is a process that affects population size Name three other process that also affect whether a population will increase or decrease in number?
I mmigration and emigration; birth and deaths
What is population of the world?
Now, in 2010, the world's population is about 6,800,000,000.
When the number of births plus immigration exceeds the number of deaths plus emigration will population size increase?
Yes. If there are more "coming" than there are "going" then the numbers increase.
How is a populations growth in rate determined for growth rate to be zero what must occur?
The number of births must be the same as the number of deaths in a population for a growth rate to be zero.
What population in Le Cameroun?
As of 2021, the population of Cameroon is estimated to be around 26 million people. This number is continually changing due to factors such as births, deaths, and migration.
What is the relationship between birth rate and death rate?
There are more people who are born then die.
Define carrying capacity and its impact on populations.?
a carrying capacity is the part of the population trend that has a stable trend with little to no changes making the population have a steady trend. its impact on populations has a major impact if the population is below the carrying capacity then deaths exceed births while if it is over then births exceed deaths.
What factors can change a population's size?
Birth Death Immigration Emigration In addition the availability of resources such as food, water, space etc ; the presence of predators, climatic conditions, natural disasters, epidemics also could affect a population size.
