China, officially the People's Republic of China (PRC), is a country in East Asia. With a population exceeding 1.4 billion, it is the world's second-most-populous country. China spans the equivalent of five time zones and borders fourteen countries by land. With an area of nearly 9.6 million square kilometers (3,700,000 sq mi), it is the third-largest country by total land area. The country is divided into 22 provinces, five autonomous regions, four municipalities, and two semi-autonomous special administrative regions. Beijing is the national capital, while Shanghai is the most populous city and largest financial center.
Population is the term typically used to refer to the number of people in a single area. Governments conduct a census to quantify the size of a resident population within a given jurisdiction. The term is also applied to non-human animals, microorganisms, and plants, and has specific uses within such fields as ecology and genetics.
The one-child policy was a population planning initiative in China implemented between 1979 and 2015 to curb the country's population growth by restricting many families to a single child. The program had wide-ranging social, cultural, economic, and demographic effects, although the contribution of one-child restrictions to the broader program has been the subject of controversy. Its efficacy in reducing birth rates and defensibility from a human rights perspective have been subjects of controversy.
Human population planning is the practice of managing the growth rate of a human population. The practice, traditionally referred to as population control, had historically been implemented mainly with the goal of increasing population growth, though from the 1950s to the 1980s, concerns about overpopulation and its effects on poverty, the environment and political stability led to efforts to reduce population growth rates in many countries. More recently, however, several countries such as China, Japan, South Korea, Russia, Iran, Italy, Spain, Finland, Hungary and Estonia have begun efforts to boost birth rates once again, generally as a response to looming demographic crises.
Family planning is the consideration of the number of children a person wishes to have, including the choice to have no children, and the age at which they wish to have them. Things that may play a role on family planning decisions include marital situation, career or work considerations, financial situations. If sexually active, family planning may involve the use of contraception and other techniques to control the timing of reproduction.
Paul Ralph Ehrlich is an American biologist known for his predictions and warnings about the consequences of population growth, including famine and resource depletion. Ehrlich is the Bing Professor Emeritus of Population Studies of the Department of Biology of Stanford University, and President of Stanford's Center for Conservation Biology.
Eco-capitalism, also known as environmental capitalism or (sometimes) green capitalism, is the view that capital exists in nature as "natural capital" on which all wealth depends. Therefore, governments should use market-based policy-instruments to resolve environmental problems.
Population ageing is an increasing median age in a population because of declining fertility rates and rising life expectancy. Most countries have rising life expectancy and an ageing population, trends that emerged first in developed countries but are now seen in virtually all developing countries. That is the case for every country in the world except the 18 countries designated as "demographic outliers" by the United Nations. The aged population is currently at its highest level in human history. The UN predicts the rate of population ageing in the 21st century will exceed that of the previous century. The number of people aged 60 years and over has tripled since 1950 and reached 600 million in 2000 and surpassed 700 million in 2006. It is projected that the combined senior and geriatric population will reach 2.1 billion by 2050. Countries vary significantly in terms of the degree and pace of ageing, and the UN expects populations that began ageing later will have less time to adapt to its implications.
Anne Howland Ehrlich is an American scientist and author who is best known for the predictions she made as a co-author of The Population Bomb with her colleague and husband, Paul R. Ehrlich. She has written or co-written more than thirty books on overpopulation and ecology, including The Stork and the Plow (1995), with Gretchen Daily, and The Dominant Animal: Human Evolution and the Environment (2008), among many other works. She also has written extensively on issues of public concern such as population control, environmental protection, and environmental consequences of nuclear war.
An only child is a person with no siblings, by birth or adoption.
Iran had a comprehensive and effective program of family planning since the beginning of the 1990s. While Iran's population grew at a rate of more than 3% per year between 1956 and 1986, the growth rate began to decline in the late 1980s and early 1990s after the government initiated a major population control program. By 2007 the growth rate had declined to 0.7 percent per year, with a birth rate of 17 per 1,000 persons and a death rate of 6 per 1,000. Reports by the UN show birth control policies in Iran to be effective with the country topping the list of greatest fertility decreases. UN's Population Division of the Department of Economic and Social Affairs says that between 1975 and 1980, the total fertility number was 6.5. The projected level for Iran's 2005 to 2010 birth rate is fewer than two.
Steven Westley Mosher is an American social scientist, anti-abortion activist, neoconservative, anti-communist, and president of the Population Research Institute (PRI), which opposes population control and abortion. In the early 1990s, he was the director of the Claremont Institute's Asian Study Center, as well as a member of the US Commission on Broadcasting to China. He is the author of several books concerning China.
The Population Research Institute (PRI) is a 501(c)3 non-profit organization based in Front Royal, Virginia, US. The organization opposes abortion. They believe that overpopulation is a myth, and oppose hormonal birth control in females and vasectomies in males. In addition, the organization issues opinion pieces questioning the veracity of human driven climate change and the natural origin of COVID-19.
Human overpopulation describes a concern that human populations may become too large to be sustained by their environment or resources in the long term. The topic is usually discussed in the context of world population, though it may concern individual nations, regions, and cities.
Overpopulation or overabundance is a phenomenon in which a species' population becomes larger than the carrying capacity of its environment. This may be caused by increased birth rates, lowered mortality rates, reduced predation or large scale migration, leading to an overabundant species and other animals in the ecosystem competing for food, space, and resources. The animals in an overpopulated area may then be forced to migrate to areas not typically inhabited, or die off without access to necessary resources.
In environmental science, a population "overshoots" its local carrying capacity — the capacity of the biome to feed and sustain that population — when that population has not only begun to outstrip its food supply in excess of regeneration, but actually shot past that point, setting up a potentially catastrophic crash of that feeder population once its food populations have been consumed completely. Overshoot can apply to human overpopulation as well as other animal populations: any life-form that consumes others to sustain itself.
John Paul Holdren is an American scientist who served as the senior advisor to President Barack Obama on science and technology issues through his roles as assistant to the president for science and technology, director of the White House Office of Science and Technology Policy, and co-chair of the President's Council of Advisors on Science and Technology (PCAST).
China's family planning policies have included specific birth quotas as well as harsh enforcements of such quotas. Together, these elements constitute the population planning program of the People's Republic of China. China's program should not be confused with the family planning programs instituted in other countries, which were designed to encourage parents to have the number of children they desired—in China, the provision of contraception through family planning programs was subservient to a birth planning program under which the government designated how many births parents could have in order to control the size of its population.
China has a history of female infanticide which spans 2,000 years. When Christian missionaries arrived in China in the late sixteenth century, they witnessed newborns being thrown into rivers or onto rubbish piles. In the seventeenth century Matteo Ricci documented that the practice occurred in several of China's provinces and said that the primary reason for the practice was poverty. The practice continued into the 19th century and declined precipitously during the Communist era, but has reemerged as an issue since the introduction of the one-child policy in the early 1980s. The 2020 census showed a male-to-female ratio of 105.07 to 100 for mainland China, a record low since the People's Republic of China began conducting censuses. Every year in China and India alone, there are close to two million instances of some form of female infanticide.
Sustainable population refers to a proposed sustainable human population of Earth or a particular region of Earth, such as a nation or continent. Estimates vary widely, with estimates based on different figures ranging from 0.65 billion people to 9.8 billion, with 8 billion people being a typical estimate. Projections of population growth, evaluations of overconsumption and associated human pressures on the environment have led to some to advocate for what they consider a sustainable population. Proposed policy solutions vary, including sustainable development, female education, family planning and broad human population planning.
