Population
A population is a summation of all the organisms of the same group or species, which live in a particular geographical area, and have the capability of interbreeding.
In ecology, the population of a certain species in a certain area is estimated using the Lincoln Index. The area that is used to define a sexual population is defined as the area where inter-breeding is potentially possible between any pair within the area. The probability of interbreeding is greater than the probability of cross-breeding with individuals from other areas. Under normal conditions, breeding is substantially more common within the area than across the border.
In sociology, population refers to a collection of humans. Demography is a social science which entails the statistical study of human populations. This article refers mainly to human population.
Population genetics (ecology)
In population genetics a sexual population is a set of organisms in which any pair of members can breed together. This means that they can regularly exchange gametes to produce normally-fertile offspring, and such a breeding group is also known therefore as a gamodeme. This also implies that all members belong to the same of species, such as humans. If the gamodeme is very large (theoretically, approaching infinity), and all gene alleles are uniformly distributed by the gametes within it, the gamodeme is said to be panmictic. Under this state, allele (gamete) frequencies can be converted to genotype (zygote) frequencies by expanding an appropriate quadratic equation, as shown by Sir Ronald Fisher in his establishment of quantitative genetics.

Populations
050 - Populations Paul Andersen explains how populations interact in an ecosystem. The symbiosis of several populations is based on effects that may be neutral, positive, or negative. Interactions like mutualism, commensalism and parasitism are included. Human impacts to ecosystems are also considered using the invasive species kudzu. Do you speak another language?

How Populations Grow and Change: Crash Course Geography #33
Is the world overpopulated or underpopulated? While we worry about there being too many people for the planet to support, we can also worry about how fewer people in a given place may affect the economy, what may happen when there are more elderly people who need care than there are healthcare workers, or even be concerned about how many people are necessary to carry on other aspects of culture. Today, we'll discuss Malthusian and Boserup predictions on the planet's carrying capacity and take a close look at a popular demography tool geographers use to predict population change: the Demographic Transition Model or DTM.

Population Ecology: The Texas Mosquito Mystery - Crash Course Ecology #2
Population ecology is the study of groups within a species that interact mostly with each other, and it examines how they live together in one geographic area to understand why these populations are different in one time and place than they are in another. How is that in any way useful to anyone ever? Hank uses the example of the West Nile virus outbreak in Texas to show you in this episode of Crash Course: Ecology.

Human Population Through Time (Updated in 2023)
It took most of human history for our population to reach 1 billion—and just over 200 years to reach 8 billion. But growth has begun slowing, as women have fewer babies on average. When will our global population peak? And how can we minimize our impact on Earth’s resources, even as we approach 10 billion? #humans #population #humanevolution #overpopulation Related content: Population Connection http://worldpopulationhistory.org/map/1/mercator/1/0/25/ UN World Population Prospects https://esa.un.org/unpd/wpp/ Real-time population counter http://www.worldometers.info/world-population/ NASA EarthData https://earthdata.nasa.gov NASA Socioeconomic Data and Applications Center http://sedac.ciesin.columbia.edu Video credits: Writer/Producer AMNH/L.

China's ageing population: Can the country afford to grow old? | BBC News
China's leaders are trying to find ways to battle what many economists have described as a demographic ticking time bomb. A slowing economy, shrinking government benefits and a decades-long one-child policy have created a creeping demographic crisis in Xi Jinping's China. The pension pot is running dry and the country is running out of time to build enough of a fund to care for the growing number of elderly. Over the next decade, about 300 million people, who are currently aged 50 to 60, are set to leave the Chinese workforce. So can China afford to grow old?

It took most of human history for our population to reach 1 billion—and just over 200 years to reach 8 billion. But growth has begun slowing, as women have fewer babies on average. When will our global population peak? And how can we minimize our impact on Earth’s resources, even as we approach 10 billion?

Population statistics are like crystal balls -- when examined closely, they can help predict a country's future (and give important clues about the past). Kim Preshoff explains how using a visual tool called a population pyramid helps policymakers and social scientists make sense of the statistics, using three different countries' pyramids as examples.

China's leaders are trying to find ways to battle what many economists have described as a demographic ticking time bomb.
A slowing economy, shrinking government benefits and a decades-long one-child policy have created a creeping demographic crisis in Xi Jinping's China.
The pension pot is running dry and the country is running out of time to build enough of a fund to care for the growing number of elderly.
Over the next decade, about 300 million people, who are currently aged 50 to 60, are set to leave the Chinese workforce.
So can China afford to grow old?

Paul Andersen explains how populations interact in an ecosystem. The symbiosis of several populations is based on effects that may be neutral, positive, or negative. Interactions like mutualism, commensalism and parasitism are included. Human impacts to ecosystems are also considered using the invasive species kudzu.

Is the world overpopulated or underpopulated? While we worry about there being too many people for the planet to support, we can also worry about how fewer people in a given place may affect the economy, what may happen when there are more elderly people who need care than there are healthcare workers, or even be concerned about how many people are necessary to carry on other aspects of culture. Today, we'll discuss Malthusian and Boserup predictions on the planet's carrying capacity and take a close look at a popular demography tool geographers use to predict population change: the Demographic Transition Model or DTM.

Population ecology is the study of groups within a species that interact mostly with each other, and it examines how they live together in one geographic area to understand why these populations are different in one time and place than they are in another. How is that in any way useful to anyone ever? Hank uses the example of the West Nile virus outbreak in Texas to show you in this episode of Crash Course: Ecology.

It took most of human history for our population to reach 1 billion—and just over 200 years to reach 8 billion. But growth has begun slowing, as women have fewer babies on average. When will our global population peak? And how can we minimize our impact on Earth’s resources, even as we approach 10 billion?

China's leaders are trying to find ways to battle what many economists have described as a demographic ticking time bomb.
A slowing economy, shrinking government benefits and a decades-long one-child policy have created a creeping demographic crisis in Xi Jinping's China.
The pension pot is running dry and the country is running out of time to build enough of a fund to care for the growing number of elderly.
Over the next decade, about 300 million people, who are currently aged 50 to 60, are set to leave the Chinese workforce.
So can China afford to grow old?

Population
A population is a summation of all the organisms of the same group or species, which live in a particular geographical area, and have the capability of interbreeding.
In ecology, the population of a certain species in a certain area is estimated using the Lincoln Index. The area that is used to define a sexual population is defined as the area where inter-breeding is potentially possible between any pair within the area. The probability of interbreeding is greater than the probability of cross-breeding with individuals from other areas. Under normal conditions, breeding is substantially more common within the area than across the border.
In sociology, population refers to a collection of humans. Demography is a social science which entails the statistical study of human populations. This article refers mainly to human population.
Population genetics (ecology)
In population genetics a sexual population is a set of organisms in which any pair of members can breed together. This means that they can regularly exchange gametes to produce normally-fertile offspring, and such a breeding group is also known therefore as a gamodeme. This also implies that all members belong to the same of species, such as humans. If the gamodeme is very large (theoretically, approaching infinity), and all gene alleles are uniformly distributed by the gametes within it, the gamodeme is said to be panmictic. Under this state, allele (gamete) frequencies can be converted to genotype (zygote) frequencies by expanding an appropriate quadratic equation, as shown by Sir Ronald Fisher in his establishment of quantitative genetics.
