Human population planning

From Wikipedia, the free encyclopedia
Map of countries by fertility rate (2018), according to CIA World Factbook

Human reproduction planning is the practice of intentionally controlling the rate of growth of a human population. Historically, human population planning has been implemented with the goal of increasing the rate of human population growth. However, in the period from the 1950s to the 1980s, concerns about global population growth and its effects on poverty, environmental degradation and political stability led to efforts to reduce human population growth rates. More recently, some countries, such as China, Iran, and Spain, have begun efforts to increase their birth rates once again. While population planning can involve measures that improve people's lives by giving them greater control of their reproduction, a few programs, most notably the Chinese government's "one-child policy and two-child policy", have resorted to coercive measures.

Types

Four types of population planning goals pursued by governments can be identified:
  1. Increasing the overall population growth rate
  2. Reducing the overall population growth rate
  3. Decreasing the relative population growth of a less favored subgroup of a national population or ethnic group, such as people of low intelligence or people with disabilities. This is known as eugenics.
  4. Instead of trying to control the rate of population growth per se, trying to arrange things so that all population groups of a certain type (e.g. all social classes within a society) have the same average rate of population growth.

Methods

While a specific population planning practice may be legal/mandated in one country, it may be illegal or restricted in another, indicative of the controversy surrounding this topic.

Reducing population growth

Population planning that is intended to reduce a population or sub-population's growth rates may promote or enforce one or more of the following practices, although there are other methods:
  • War (Wars that are done on purpose or in aggression can cause casualties that lower the population. For instance in the Iraq War approximately 1 million people died.)
  • Higher taxation of parents who have too many children
  • Contraception
  • Abstinence

The method(s) chosen can be strongly influenced by the religious and cultural beliefs of community members. The failure of other methods of population planning can lead to the use of abortion or infanticide as solutions.

Increasing population growth

Population policies that are intended to increase a population or subpopulation growth rates may use practices such as:
  • Higher taxation of married couples who have no, or too few, children
  • Politicians imploring the populace to have bigger families
  • Tax breaks and subsidies for families with children
  • Loosening of immigration restrictions, and/or mass recruitment of foreign workers by the government

History

Ancient times through Middle Ages

A number of ancient writers have reflected on the issue of population. At about 300 BC, the Indian political philosopher Chanakya (c. 350-283 BC) considered population a source of political, economic, and military strength. Though a given region can house too many or too few people, he considered the latter possibility to be the greater evil. Chanakya favored the remarriage of widows (which at the time was forbidden in India), opposed taxes encouraging emigration, and believed in restricting asceticism to the aged.

In ancient Greece, Plato (427-347 BC) and Aristotle (384-322 BC) discussed the best population size for Greek city-states such as Sparta, and concluded that cities should be small enough for efficient administration and direct citizen participation in public affairs, but at the same time needed to be large enough to defend themselves against hostile neighbors. In order to maintain a desired population size, the philosophers advised that procreation, and if necessary, immigration, should be encouraged if the population size was too small. Emigration to colonies would be encouraged should the population become too large. Aristotle concluded that a large increase in population would bring, "certain poverty on the citizenry and poverty is the cause of sedition and evil." To halt rapid population increase, Aristotle advocated the use of abortion and the exposure of newborns (that is, infanticide).

Confucius (551-478 BC) and other Chinese writers cautioned that, "excessive growth may reduce output per worker, repress levels of living for the masses and engender strife." Confucius also observed that, "mortality increases when food supply is insufficient; that premature marriage makes for high infantile mortality rates, that war checks population growth."

Ancient Rome, especially in the time of Augustus (63 BC-AD 14), needed manpower to acquire and administer the vast Roman Empire. A series of laws were instituted to encourage early marriage and frequent childbirth. Lex Julia (18 BC) and the Lex Papia Poppaea (AD 9) are two well-known examples of such laws, which among others, provided tax breaks and preferential treatment when applying for public office for those that complied with the laws. Severe limitations were imposed on those who did not. For example, the surviving spouse of a childless couple could only inherit one-tenth of the deceased fortune, while the rest was taken by the state. These laws encountered resistance from the population which led to the disregard of their provisions and to their eventual abolition.

Tertullian, an early Christian author (ca. AD 160-220), was one of the first to describe famine and war as factors that can prevent overpopulation. He wrote: "The strongest witness is the vast population of the earth to which we are a burden and she scarcely can provide for our needs; as our demands grow greater, our complaints against Nature's inadequacy are heard by all. The scourges of pestilence, famine, wars, and earthquakes have come to be regarded as a blessing to overcrowded nations since they serve to prune away the luxuriant growth of the human race."

Ibn Khaldun, a North African Arab polymath (1332–1406), considered population changes to be connected to economic development, linking high birth rates and low death rates to times of economic upswing, and low birth rates and high death rates to economic downswing. Khaldoun concluded that high population density rather than high absolute population numbers were desirable to achieve more efficient division of labour and cheap administration.

During the Middle Ages in Christian Europe, population issues were rarely discussed in isolation. Attitudes were generally pro-natalist in line with the Biblical command, "Be ye fruitful and multiply."

16th and 17th centuries

European cities grew more rapidly than before, and throughout the 16th century and early 17th century discussions on the advantages and disadvantages of population growth were frequent. Niccolò Machiavelli, an Italian Renaissance political philosopher, wrote, "When every province of the world so teems with inhabitants that they can neither subsist where they are nor remove themselves elsewhere... the world will purge itself in one or another of these three ways," listing floods, plague and famine. Martin Luther concluded, "God makes children. He is also going to feed them."

Jean Bodin, a French jurist and political philosopher (1530–1596), argued that larger populations meant more production and more exports, increasing the wealth of a country. Giovanni Botero, an Italian priest and diplomat (1540–1617), emphasized that, "the greatness of a city rests on the multitude of its inhabitants and their power," but pointed out that a population cannot increase beyond its food supply. If this limit was approached, late marriage, emigration, and the war would serve to restore the balance.

Richard Hakluyt, an English writer (1527–1616), observed that, "Through our longe peace and seldom sickness... we are grown more populous than ever heretofore;... many thousands of idle persons are within this realme, which, having no way to be sett on work, be either mutinous and seek alteration in the state, or at least very burdensome to the commonwealth." Hakluyt believed that this led to crime and full jails and in A Discourse on Western Planting (1584), Hakluyt advocated for the emigration of the surplus population. With the onset of the Thirty Years' War (1618–48), characterized by widespread devastation and deaths brought on by hunger and disease in Europe, concerns about depopulation returned.

Population planning movement

In the 20th century, population planning proponents have drawn from the insights of Thomas Malthus, a British clergyman and economist who published An Essay on the Principle of Population in 1798. Malthus argued that, "Population, when unchecked, increases in a geometrical ratio. Subsistence only increases in an arithmetical ratio." He also outlined the idea of "positive checks" and "preventative checks." "Positive checks", such as diseases, wars, disasters, famines, and genocides are factors which Malthus believed could increase the death rate. "Preventative checks" were factors which Malthus believed could affect the birth rate such as moral restraint, abstinence and birth control. He predicted that "positive checks" on exponential population growth would ultimately save humanity from itself and he also believed that human misery was an "absolute necessary consequence." Malthus went on to explain why he believed that this misery affected the poor in a disproportionate manner. 

There is a constant effort towards an increase in population which tends to subject the lower classes of society to distress and to prevent any great permanent amelioration of their condition…. The way in which these effects are produced seems to be this. We will suppose the means of subsistence in any country just equal to the easy support of its inhabitants. The constant effort towards population... increases the number of people before the means of subsistence are increased. The food, therefore which before supplied seven million must now be divided among seven million and a half or eight million. The poor consequently must live much worse, and many of them are reduced to severe distress.
Finally, Malthus advocated for the education of the lower class about the use of "moral restraint" or voluntary abstinence, which he believed would slow the growth rate.

Paul R. Ehrlich, a US biologist and environmentalist, published The Population Bomb in 1968, advocating stringent population planning policies. His central argument on population is as follows:
A cancer is an uncontrolled multiplication of cells; the population explosion is an uncontrolled multiplication of people. Treating only the symptoms of cancer may make the victim more comfortable at first, but eventually, he dies - often horribly. A similar fate awaits a world with a population explosion if only the symptoms are treated. We must shift our efforts from the treatment of the symptoms to the cutting out of cancer. The operation will demand many apparently brutal and heartless decisions. The pain may be intense. But the disease is so far advanced that only with radical surgery does the patient have a chance to survive.

In his concluding chapter, Ehrlich offered a partial solution to the "population problem," "[We need] compulsory birth regulation... [through] the addition of temporary sterilants to water supplies or staple food. Doses of the antidote would be carefully rationed by the government to produce the desired family size".

Ehrlich's views came to be accepted by many population planning advocates in the United States and Europe in the 1960s and 1970s. Since Ehrlich introduced his idea of the "population bomb," overpopulation has been blamed for a variety of issues, including increasing poverty, high unemployment rates, environmental degradation, famine and genocide. In a 2004 interview, Ehrlich reviewed the predictions in his book and found that while the specific dates within his predictions may have been wrong, his predictions about climate change and disease were valid. Ehrlich continued to advocate for population planning and co-authored the book The Population Explosion, released in 1990 with his wife Anne Ehrlich.

However, it is controversial as to whether human population stabilization will avert environmental risks.

Paige Whaley Eager argues that the shift in perception that occurred in the 1960s must be understood in the context of the demographic changes that took place at the time. It was only in the first decade of the 19th century that the world's population reached one billion. The second billion was added in the 1930s, and the next billion in the 1960s. 90 percent of this net increase occurred in developing countries. Eager also argues that, at the time, the United States recognised that these demographic changes could significantly affect global geopolitics. Large increases occurred in China, Mexico and Nigeria, and demographers warned of a "population explosion," particularly in developing countries from the mid-1950s onwards.

In the 1980s, tension grew between population planning advocates and women's health activists who advanced women's reproductive rights as part of a human rights-based approach. Growing opposition to the narrow population planning focus led to a significant change in population planning policies in the early 1990s.

Population planning and economics

Opinions vary among economists about the effects of population change on a nation's economic health. US scientific research in 2009 concluded that the raising of a child cost about $16,000 yearly ($291,570 total for raising the child to its 18th birthday). In the US, the multiplication of this number with the yearly population growth will yield the overall cost of the population growth. Costs for other developed countries are usually of a similar order of magnitude.

Some economists, such as Thomas Sowell and Walter E. Williams, have argued that poverty and famine are caused by bad government and bad economic policies, not by overpopulation.

In his book The Ultimate Resource, economist Julian Simon argued that higher population density leads to more specialization and technological innovation, which in turn leads to a higher standard of living. He claimed that human beings are the ultimate resource since we possess "productive and inventive minds that help find creative solutions to man’s problems, thus leaving us better off over the long run". He also claimed that, "Our species is better off in just about every measurable material way."

Simon also claimed that when considering a list of countries ranked in order by population density, there is no correlation between population density and poverty and starvation. Instead, if a list of countries is considered according to corruption within their respective governments, there is a significant correlation between government corruption, poverty and famine.

Views on population planning

Population increase reductions

Support

As early as 1798, Thomas Malthus argued in his Essay on the Principle of Population for implementation of population planning. Around the year 1900, Sir Francis Galton said in his publication Hereditary Improvement: "The unfit could become enemies to the State if they continue to propagate." In 1968, Paul Ehrlich noted in The Population Bomb, "We must cut the cancer of population growth", and "if this was not done, there would be only one other solution, namely the 'death rate solution' in which we raise the death rate through war-famine-pestilence, etc.”

In the same year, another prominent modern advocate for mandatory population planning was Garrett Hardin, who proposed in his landmark 1968 essay Tragedy of the commons, society must relinquish the "freedom to breed" through "mutual coercion, mutually agreed upon." Later on, in 1972, he reaffirmed his support in his new essay "Exploring New Ethics for Survival", by stating, " We are breeding ourselves into oblivion." Many prominent personalities, such as Bertrand Russell, Margaret Sanger (1939), John D. Rockefeller, Frederick Osborn (1952), Isaac Asimov, Arne Næss and Jacques Cousteau have also advocated for population planning. Today, a number of influential people advocate population planning such as these:
The head of the UN Millennium Project Jeffrey Sachs is also a strong proponent of decreasing the effects of overpopulation. In 2007, Jeffrey Sachs gave a number of lectures (2007 Reith Lectures) about population planning and overpopulation. In his lectures, called "Bursting at the Seams", he featured an integrated approach that would deal with a number of problems associated with overpopulation and poverty reduction. For example, when criticized for advocating mosquito nets he argued that child survival was, "by far one of the most powerful ways," to achieve fertility reduction, as this would assure poor families that the smaller number of children they had would survive.

Opposition

The Roman Catholic Church has opposed abortion, sterilization, and artificial contraception as a general practice but especially in regard to population planning policies. Pope Benedict XVI has stated, "The extermination of millions of unborn children, in the name of the fight against poverty, actually constitutes the destruction of the poorest of all human beings." The reformed Theology pastor Dr. Stephen Tong also opposes the planning of human population.

Natalism

The Nation has criticised some white Quiverfull families for having large families motivated by demographic change and worries about "race suicide".

Pro-natalist policies

In 1946, Poland introduced a tax on childlessness, discontinued in the 1970s, as part of natalist policies in the Communist government. From 1941 to the 1990s, the Soviet Union had a similar tax to replenish the population losses incurred during the Second World War. 

The Socialist Republic of Romania under Nicolae Ceaușescu severely repressed abortion, (the most common birth control method at the time) in 1966, and forced gynecological revisions and penalties for unmarried women and childless couples. The surge of the birth rate taxed the public services received by the decreţei 770 ("Scions of the Decree 770") generation. A consequence of Ceaușescu's natalist policy is that large numbers of children ended up living in orphanages, because their parents could not cope. The vast majority of children who lived in the communist orphanages were not actually orphans, but were simply children whose parents could not afford to raise them. The Romanian Revolution of 1989 preceded a fall in population growth.

Balanced birth policies

Nativity in the Western world dropped during the interwar period. Swedish sociologists Alva and Gunnar Myrdal published Crisis in the Population Question in 1934, suggesting an extensive welfare state with universal healthcare and childcare, to increase overall Swedish birth rates, and level the number of children at a reproductive level for all social classes in Sweden. Swedish fertility rose throughout World War II (as Sweden was largely unharmed by the war) and peaked in 1946.

Modern practice by country

Australia

Australia currently offers fortnightly Family Tax Benefit payments plus a free immunization scheme, and recently proposed to pay all child care costs for women who want to work.

China

One-child era (1979–2015)

The most significant population planning system in the world was China's one-child policy, in which, with various exceptions, having more than one child was discouraged. Unauthorized births were punished by fines, although there were also allegations of illegal forced abortions and forced sterilization. As part of China's planned birth policy, (work) unit supervisors monitored the fertility of married women and may decide whose turn it is to have a baby.

The Chinese government introduced the policy in 1978 to alleviate the social and environmental problems of China. According to government officials, the policy has helped prevent 400 million births. The success of the policy has been questioned, and reduction in fertility has also been attributed to the modernization of China. The policy is controversial both within and outside of China because of its manner of implementation and because of concerns about negative economic and social consequences e.g. female infanticide. In oriental cultures, the oldest male child has responsibility of caring for the parents in their old age. Therefore, it is common for oriental families to invest most heavily in the oldest male child, such as providing college, steering them into the most lucrative careers, and so on. To these families, having an oldest male child is paramount, so in a one-child policy, a daughter has no economic benefit, so daughters, especially as a first child, is often targeted for abortion or infanticide. China introduced several government reforms to increase retirement payments to coincide with the one-child policy. During that time, couples could request permission to have more than one child.

According to Tibetologist Melvyn Goldstein, natalist feelings run high in China's Tibet Autonomous Region, among both ordinary people and government officials. Seeing population control "as a matter of power and ethnic survival" rather than in terms of ecological sustainability, Tibetans successfully argued for an exemption of Tibetan people from the usual family planning policies in China such as the one-child policy.

Two-child era (2015-)

Map of population density by country, per square kilometer

In November 2014, the Chinese government allowed its people to conceive a second child under the supervision of government regulation.

On October 29, 2015, the ruling Chinese Communist Party announced that all one-child policies would be scrapped, allowing all couples to have two children. The change was needed to allow a better balance of male and female children, and to grow the young population to ease the problem of paying for the aging population. Two-child policy begin from January 1, 2016 and one-child policy abolished follow the beginning of two-child policy.

Hungary

The Second Orbán Government made saving the nation from the demographic abyss a key aspect and therefore has introduced generous breaks for large families and greatly increased social benefits for all families. Those with three or more children pay virtually no taxes. In just a couple years, Hungary went from being one of the countries that spend the least on families in the OECD to being one of those that do so the most. In 2015, it was almost 4% of GDP.

India

Only those with two or fewer children are eligible for election to a gram panchayat, or local government.

Us two, our two ("Hum do, hamare do" in Hindi) is a slogan meaning one family, two children and is intended to reinforce the message of family planning thereby aiding population planning.

Facilities offered by government to its employees are limited to two children. The government offers incentives for families accepted for sterilization. Moreover, India was the first country to take measures for family planning back in 1952.

Iran

After the Iran–Iraq War, Iran encouraged married couples to produce as many children as possible to replace population lost to the war.

Iran succeeded in sharply reducing its birth rate from the late 1980s to 2010. Mandatory contraceptive courses are required for both males and females before a marriage license can be obtained, and the government emphasized the benefits of smaller families and the use of contraception. This changed in 2012, when a major policy shift back towards increasing birth rates and against population planning was announced. In 2014, permanent contraception and advertising of birth control were to be outlawed.

Israel

In Israel, Haredi families with many children receive economic support through generous governmental child allowances, government assistance in housing young religious couples, as well as specific funds by their own community institutions. Haredi women have an average of 6.7 children while the average Jewish Israeli woman has 3 children.

Japan

Japan has experienced a shrinking population for many years. The government is trying to encourage women to have children or to have more children – many Japanese women do not have children, or even remain single. The population is culturally opposed to immigration.

Some Japanese localities, facing significant population loss, are offering economic incentives. Yamatsuri, a town of 7 000 just north of Tokyo, offers parents $4 600 for the birth of a child and $460 a year for 10 years.

Myanmar

In Myanmar, the Population planning Health Care Bill requires some parents to space each child three years apart. The measure is expected to be used against the persecuted Muslim Rohingyas minority.

Russia

Russian President Vladimir Putin directed Parliament in 2006 to adopt a 10-year program to stop the sharp decline in Russia's population, principally by offering financial incentives and subsidies to encourage women to have children.

Singapore

Singapore has undergone two major phases in its population planning: first to slow and reverse the baby boom in the Post-World War II era; then from the 1980s onwards to encourage couples to have more children as the birth rate had fallen below the replacement-level fertility. In addition, during the interim period, eugenics policies were adopted.

The anti-natalist policies flourished in the 1960s and 1970s: initiatives advocating small families were launched and developed into the Stop at Two programme, pushing for two-children families and promoting sterilisation. In 1984, the government announced the Graduate Mothers' Scheme, which favoured children of more well-educated mothers; the policy was however soon abandoned due to the outcry in the general election of the same year. Eventually, the government became pro-natalist in the late 1980s, marked by its Have Three or More plan in 1987. Singapore pays $3,000 for the first child, $9,000 in cash and savings for the second; and up to $18,000 each for the third and fourth.

Spain

In 2017, the government of Spain appointed Edelmira Barreira, as "minister for sex", in a pro-natalist attempt to reverse a negative population growth rate.

Turkey

In May 2012, Turkey's Prime Minister Recep Tayyip Erdogan argued that abortion is murder and announced that legislative preparations to severely limit the practice are underway. Erdogan also argued that abortion and C-section deliveries are plots to stall Turkey's economic growth. Prior to this move, Erdogan had repeatedly demanded that each couple have at least three children.

United States

Enacted in 1970, Title X of the Public Health Service Act provides access to contraceptive services, supplies and information to those in need. Priority for services is given to people with low incomes. The Title X Family Planning program is administered through the Office of Population Affairs under the Office of Public Health and Science. It is directed by the Office of Family Planning. In 2007, Congress appropriated roughly $283 million for family planning under Title X, at least 90 percent of which was used for services in family planning clinics. Title X is a vital source of funding for family planning clinics throughout the nation, which provide reproductive health care, including abortion. 

The education and services supplied by the Title X-funded clinics support young individuals and low-income families. The goals of developing healthy families are accomplished by helping individuals and couples decide whether to have children and when the appropriate time to do so would be.

Title X has made the prevention of unintended pregnancies possible. It has allowed millions of American women to receive necessary reproductive health care, plan their pregnancies and prevent abortions. Title X is dedicated exclusively to funding family planning and reproductive health care services.

Title X as a percentage of total public funding to family planning client services has steadily declined from 44% of total expenditures in 1980 to 12% in 2006. Medicaid has increased from 20% to 71% in the same time. In 2006, Medicaid contributed $1.3 billion to public family planning.

Natalism in the United States

In a 2004 editorial in The New York Times, David Brooks expressed the opinion that the relatively high birthrate of the United States in comparison to Europe could be attributed to social groups with "natalist" attitudes. The article is referred to in an analysis of the Quiverfull movement. However, the figures identified for the demographic are extremely low. 

Former US Senator Rick Santorum made natalism part of his platform for his 2012 presidential campaign. This is not an isolated case. Many of those categorized in the General Social Survey as "Fundamentalist Protestant" are more or less natalist, and have a higher birth rate than "Moderate" and "Liberal" Protestants. However, Rick Santorum is not a Protestant but a practicing Catholic.

Uzbekistan

It is reported that Uzbekistan has been pursuing a policy of forced sterilizations, hysterectomies and IUD insertions since the late 1990s in order to impose population planning.

Population decline

From Wikipedia, the free encyclopedia

A population decline (or depopulation) in humans is a reduction in a human population caused by events such as long-term demographic trends, as in sub-replacement fertility, emigration, for example as a result of economic recession, urban decay, rural flight, food resource decline or high death rates due to violence, disease, or other catastrophes. Depopulation in humans can be largely beneficial for a region, allocating more resources with less or no competition for the new population. In addition to exempting the disadvantages of overpopulation, such as increased traffic, pollution, real estate prices, environmental destruction, and fossil fuel usage, etc. Per-capita wealth may increase in depopulation scenarios, in addition to improvement of environmental quality-of-life indicators such as improved air and water quality, reforestation, return of native species such as coral reefs and mangroves, reduction of carbon emissions, etc. The accompanying benefits of depopulation have been termed shrink and prosper, with benefits being similar to the post-Civil War Gilded Age, post-World War I economic boom, and the post-World War II economic boom.

Causes

A reduction over time in a region's population can be caused by several factors including sub-replacement fertility (along with limited immigration), heavy emigration, disease, famine, and war. History is replete with examples of large-scale depopulations. Many wars, for example, have been accompanied by significant depopulations. Before the 20th century, population decline was mostly due to disease, starvation, epidemic or emigration. The Black Death in Europe, the arrival of Old World diseases to the Americas, the tsetse fly invasion of the Waterberg Massif in South Africa, and the Great Irish Famine all caused sizable population declines. In modern times, the AIDS epidemic caused declines in the population of some African countries. Less frequently, population declines are caused by genocide or mass execution; for example, in the 1970s, the population of Cambodia declined because of wide-scale executions by the Khmer Rouge.

Underpopulation

Sometimes the term underpopulation is applied to a specific economic system does not refer to carrying capacity, and is not a term in opposition to overpopulation, which deals with the total possible population can be sustained by available food, water, sanitation and other infrastructure. "Underpopulation" is usually defined as a state in which a country's population has declined too much to support its current economic system. Thus the term has nothing to do with the biological aspects of carrying capacity, but is an economic employed to imply that the transfer payment schemes of some developed countries might fail once the population declines to a certain point. An example would be if retirees were supported through a social security system which does not invest savings, and then a large emigration movement occurred. In this case, the younger generation may not be able to support the older generations.

Positive effects of a population decline

A long-term decline in birth rates has a positive effect on the labour market due a decreasing number of job applicants. A phenomenon of a declining youth unemployment was observed in Germany in 2010 and 2011. From population decline the competition for resources within the population is reduced. Population decline also can rise the income per capita. Additionally, the life quality increases due to lower motorised traffic, less environmental destruction, reduced carbon and nitrogen emissions, reduced pollution, reforestation and better air and water quality due to industries operating for fewer hours and increased carbon sinks. 

The human carrying capacity of the Earth is estimated to 500 million according to the National Strategy for a Sustainable America, other authors estimate 1 to 12 billion. According to these studies, the human carrying capacity is already exceeded or would be exceeded by 2100, therefore a global population decline would counteract the negative effects of human overpopulation.

Changing historic trends in world population growth

From pre-history (cir 10,000 BC) to the beginning of the Early Modern Period (generally 1500 – 1800), world population grew very slowly, around 0.04% per year.  During that period, population growth was governed by conditions now labeled the “Malthusian Trap”.

After 1700, driven by increases in human productivity produced by the Industrial Revolution, population growth accelerated to around 0.6% per year, a rate that was over ten times the rate of population growth of the previous 12,000 years. This rapid increase in global population caused Malthus and others to raise the first concerns about “overpopulation”.

After World War I birth rates in the United States and many European countries fell below replacement level.  This prompted concern about population decline. The recovery of the birth rate in most western countries around 1940 that produced the “baby boom”, with growth rates in the 1.0 – 1.5% range, and which peaked in 1962 at 2.1% per year, temporarily dispelled prior concerns about population decline, and the world [DJS - HOW CAN THE WORLD HAVE FEELINGS?] was once again fearful of overpopulation.

But, after 1962 the global population growth rate started a long decline and today (the period 2015-2020) is estimated to be about 1.1%, half of its peak in 1962. Although still growing, global population is predicted to level out around the end of the 21st century, and some sources predict the start of a decline before then.  The principle cause of this phenomenon is the abrupt decline in the global total fertility rate, from 5.0 in 1960 to 2.5 in 2016. The decline in the total fertility rate has occurred in every region of the world and has brought renewed concern for population decline.

The era of rapid global population increase, and concomitant concern about a population explosion, has been a relative short one compared with the span of human history.  It began roughly at the beginning of the industrial revolution and appears to be now drawing to a close in the Western world.

Interpretation of statistical data

Statistical data, especially those comparing only two sets of figures, can be misleading and may require careful interpretation. For instance a nation's population could have been increasing, but a one-off event could have resulted in a short-term decline; or vice versa. Nations can acquire territory or lose territory, and groups of people can acquire or lose citizenship, e.g. stateless persons, indigenous people, and illegal immigrants or long-stay foreign residents. Political instability can make it difficult to conduct a census in certain regions. Further, a country's population could rise in summer and decline in winter as deaths increase in winter in cold regions; a long census interval could show a rise in population when the population has already tipped into decline.

White nationalists use evidence of a declining birth rate in support of their extremist views and calls to violence. Lower fertility rates are generally associated with dramatic increases in population health and longevity. Increasing populations are not necessary to maintain economic growth and social vitality because of advances in automation and workers living healthy lives much longer into old age. Declining populations require fewer scarce resources and pollute less. Fewer dependents mean that families, regions, and societies can achieve more productive uses of available resources and increase their quality of life. While there were in the past advantages to high fertility rates, that "demographic dividend" has now largely disappeared.

Contemporary decline by country

The table below shows that a number of countries are declining in population, in particular Puerto Rico, Latvia, Lithuania and Venezuela

The term population used here is based on the de facto definition of population, which counts all residents regardless of legal status or citizenship, except for refugees not permanently settled in the country of asylum, who are generally considered part of the population of the country of origin. This means that population growth in this table includes net changes from immigration and emigration. For a table of natural population changes, see list of countries by natural increase.

Long-term future trends

A long-term population decline is typically caused by sub-replacement fertility, coupled with a net immigration rate that fails to compensate the excess of deaths over births. A long-term decline is accompanied by population aging and creates an increase in the ratio of retirees to workers and children. When a sub-replacement fertility rate remains constant, population decline accelerates over the long term.

Because of the global decline in the fertility rate, projections of future global population show a marked slowing of population growth and the possibility of long-term decline.

The table below summarizes the United Nations' predictions of future population growth. The UN divides the world into six regions. Their forecast shows that during the period 2045-2050 Europe's population will be in decline and all other regions will experience significant reductions in growth. Furthermore, the UN predicts that by the end of the 21st century (the period 2095-2100) three of these regions will be showing population decline and global population growth will be zero.

Annual Percent Change of Population for Three Periods in the Future
Region 2020-25 2045-50 2095-2100
Africa 2.4% 1.7% 0.6%
Asia 0.8 0.1 -0.4
Europe 0.0 -0.3 -0.1
Latin America & the Caribbean 0.8 0.2 -0.5
Oceania 1.2 0.8 0.4
The World 1.0 0.5 0.0

The table shows that the UN predicts long-term decline of population growth rates in every region; however, short-term baby booms and healthcare improvements, among other factors, can cause reversals of trends. Population declines in Russia (1995-2010), Germany (1975-1985), and Ireland (1950-1960) have seen long-term reversals. The UK, having seen almost zero growth during the period 1975-1985, is now (2015-2020) growing at 0.6% per year.

United States

Despite ever increasing population in the United States, some American municipalities have shrunk due to urban decay in large cities and rural flight in smaller towns. Detroit is the most notable of a number of cities with population smaller than in 1950 and whose population shrinkage has been the most dramatic; Detroit's population was almost 1.85 million as of the 1950 census but has plummeted to 677,000 as of 2015, with the most rapid decline occurring between 2000 and 2010.

Other American cities whose populations have shrunk substantially since the 1950s—although some have begun to grow again—include New Orleans; St. Louis; Buffalo; Philadelphia; Baltimore; Chicago; Cleveland; Pittsburgh; and Wilmington (Delaware).

Japan

Though Japan's population has been predicted to decline for years, and its monthly and even annual estimates have shown a decline in the past, the 2010 census result figure was slightly higher, at just above 128 million, than the 2005 census. Factors implicated in the higher figures were more Japanese returnees than expected as well as changes to the methodology of data collection. The official count put the population as of October 1, 2015, at 127.1 million, down by 947,000 or 0.7% from the previous census in 2010. The gender ratio is increasingly skewed; some 106 women per 100 men live in Japan. The total population is still 52% above 1950 levels. In 2013, Japan's population fell by a record-breaking 244,000. The Tōhoku region in Japan now has fewer people than in 1950.

Eastern Europe and former Soviet republics

Population is falling due to health factors and low replacement, as well as emigration of ethnic Russians to Russia. Exceptions to this rule are in those ex-Soviet states that have a Muslim majority (Uzbekistan, Turkmenistan, Tajikistan, Kyrgyzstan, and Azerbaijan), where high birth rates are traditional. Much of Eastern Europe has lost population due to migration to Western Europe. In Eastern Europe and Russia, natality fell abruptly after the end of the Soviet Union, and death rates generally rose. Together these nations occupy over 21 million km2 (8 million sq mi) and are home to over 400 million people (less than six percent of the world population), but if current trends continue, more of the developed world and some of the developing world could join this trend.

Albania

Albania's population in 1989 recorded 3,182,417 people, the largest for any census. Since then, its population declined to an estimated 2,893,005 in January 2015. This represents a decrease of 10% in total population since the peak census figure.

Armenia

Armenia's population peaked at 3,604,000 in 1991 and declined to 3,010,600 in the January 2015 state statistical estimate. This represents a 19.7% decrease in total population since the peak census figure.

Belarus

Belarus's population peaked at 10,151,806 in 1989 Census, and declined to 9,480,868 as of 2015 as estimated by the state statistical service. This represents a 7.1% decline since the peak census figure.

Bosnia and Herzegovina

Bosnia and Herzegovina's population is thought to have peaked at 4,377,033 in 1991 Census, shortly before splitting from Yugoslavia before the ensuing war. The latest census of 2013 reported 3,791,622 people. This represents a 15.4% decline since the peak census figure.

Bulgaria

Bulgaria's population declined from a peak of 9,009,018 in 1989 and since 2001, has lost yet another 600,000 people, according to 2011 census preliminary figures to no more than 7.3 million, further down to 7,245,000. This represents a 24.3% decrease in total population since the peak, and a -0.82% annual rate in the last 10 years.

Croatia

Croatia's population declined from 4,784,265 in 1991 to 4,456,096 (by old statistical method) of which 4,284,889 are permanent residents (by new statistical method), in 2011, a decline of 8% (11.5% by the new definition of permanent residency in 2011 census). The main reasons for the decline since 1991 are: low birth rates, emigration and war in Croatia. From 2001 and 2011 main reason for the drop in population is due to a difference in definition of permanent residency used in censuses till 2001 (censuses of 1948, 1953, 1961, 1971, 1981, 1991 and 2001) and the one used in 2011.

Estonia

In the last Soviet census of 1989, it had a population of 1,565,662, which was close to its peak population. The state statistics reported an estimate of 1,314,370 for 2016. This represents a 19.2% decline since the peak census figure.

Georgia

In the last Soviet census of 1989, it had a population of 5,400,841, which was close to its peak population. The state statistics reported an estimate of 4,010,000 for 2014 Census, which includes estimated numbers for quasi-independent Abkhazia and South Ossetia. This represents a 25.7% decline since the peak census figure, but nevertheless somewhat higher than the 1950 population.

Latvia

When Latvia split from the Soviet Union, it had a population of 2,666,567, which was very close to its peak population. The latest census recorded a population of 2,067,887 in 2011, while the state statistics reported an estimate of 1,986,086 for 2015. This represents a 25.5% decline since the peak census figure, only one of two nations worldwide falling below 1950 levels. The decline is caused by both a negative natural population growth (more deaths than births) and a negative net migration rate.

Lithuania

When Lithuania split from the Soviet Union, it had a population of 3.7 million, which was close to its peak population. The latest census recorded a population of 3.05 million in 2011, down from 3.4 million in 2001, further falling to 2,988,000 in September 1, 2012. This represents a 23.8% decline since the peak census figure, and some 13.7% since 2001.

Ukraine

Ukraine census in 1989 resulted in 51,452,034 people. Ukraine's own estimates show a peak of 52,244,000 people in 1993; however, this number has plummeted to 45,439,822 as of December 1, 2013. Having lost Crimean territory and experienced war, the population has plunged to 42,981,850 as of August 2014. This represents a 19.7% decrease in total population since the peak figure, but 16.8% above the 1950 population even without Crimea. Its absolute total decline (9,263,000) since its peak population is the highest of all nations; this includes loss of territory and heavy net emigration. Eastern Ukraine may yet lose many Russian-speaking citizens due to new Russian citizenship law.

Hungary

Hungary's population peaked in 1980, at 10,709,000, and has continued its decline to under 10 million as of August 2010. This represents a decline of 7.1% since its peak; however, compared to neighbors situated to the East, Hungary peaked almost a decade earlier yet the rate has been far more modest, averaging -0.23% a year over the period.

Romania

Romania's 1991 census showed 23,185,084 people, and the October 2011 census recorded 20,121,641 people, while the state statistical estimate for 2014 is 19,947,311. This represents a decrease of 16.2% since the historical peak in 1991.

Serbia

Serbia recorded a peak census population of 7,576,837 in 1991, falling to 7,186,862 in the 2011 census. That represents a decline of 5.1% since its peak census figure.

Halted declines

Russia

The decline in Russia's total population is among the largest in numbers, but not in percentage. After having peaked at 148,689,000 in 1991, the population then decreased, falling to 142,737,196 by 2008. This represents a 4.0% decrease in total population since the peak census figure. However, since then the Russian population has risen to 146,870,000 in 2018. This recent trend can be attributed to a lower death rate, higher birth rate, the annexation of Crimea and continued immigration, mostly from Ukraine and Armenia. It is some 40% above the 1950 population.

Germany

In Germany a decades-long tendency to population decline has been offset by waves of immigration. The 2011 national census recorded a population of 80.2 million people. At the end of 2012 it had risen to 82 million according to federal estimates. This represents about 14% increase over 1950.

Ireland

In the current area of the Republic of Ireland, the population has fluctuated dramatically. The population of Ireland was 8 million in 1841, but it dropped due to the Irish famine and later emigration. The population of the Republic of Ireland hit bottom at 2.8 million in the 1961 census, but it then rose and in 2011 it was 4.58 million. As of 2020 it is estimated to be just under 5 million according to the country's Central Statistics Office 

Declines within race or ethnicity

Such is the case in California, where the segment of the population considered Non-Hispanic Whites declined from 15.8 million to 14.95 million, while the total population increased from 33 million to over 37 million between 2000 and 2010 mostly thanks to immigration from Mexico and Asian countries. 

Singapore has one of the world's lowest birthrates. The ratio of native Singaporeans (whatever their ethnicity) towards immigrants and migrants continues to erode, with natives decreasing in absolute figures, despite the country planning to increase the population by over 20% in coming years.

Economic consequences

The effects of a declining population can be adverse or beneficial for an economy. Possible negative consequences are:
  1. Permanent recession
  2. A rise in the dependency ratio
  3. A crisis in end of life care for the elderly
  4. Difficulties in funding entitlement programs
  5. A decline in military strength
  6. A decline in innovation
  7. A strain on mental health
  8. Deflation
Possible benefits include:
  • Higher wages due to more demand for fewer workers.
  • More labor-saving technologies to make up for the shortfall in workers
  • More money available for investment in human capital
  • Lower rents and commodity prices, which benefits lower-class consumers
Conversely, the effects of a declining population can be positive. The single best gauge of economic success is the growth of GDP per person, not total GDP. GDP per person (also known as GDP per capita or per capita GDP) is a rough proxy for average living standards. A country can both increase its average living standard and grow total GDP even though its population growth is low or even negative. The economies of both Japan and Germany went into recovery around the time their populations began to decline (2003–2006). In other words, both the total and per capita GDP in both countries grew more rapidly after 2005 than before. Russia's economy also began to grow rapidly from 1999 onward, even though its population had been shrinking since 1992–93. Many Eastern European countries have been experiencing similar effects to Russia. Such renewed growth calls into question the conventional wisdom that economic growth requires population growth, or that economic growth is impossible during a population decline. 

More recently (2009–2017) Japan has experienced a higher growth of GDP per capita than the United States, even though its population declined over that period. In the United States, the relationship between population growth and growth of GDP per capita has been found to be empirically insignificant. All of this is further proof that individual prosperity can grow during periods of population decline.

Predictions of the net economic (and other) effects from a slow and continuous population decline (e.g. due to low fertility rates) are mainly theoretical since such a phenomenon is a relatively new and unprecedented one. A recent meta-study found no relationship between population growth and economic growth.

In an attempt to better understand the economic impact of these pluses and minuses, Lee et al. analyzed data from 40 countries. They found that fertility well above replacement and population growth would typically be most beneficial for government budgets. However, fertility near replacement and population stability would be most beneficial for standards of living when the analysis includes the effects of age structure on families as well as governments. And fertility moderately below replacement and population decline would maximize standards of living when the cost of providing capital for a growing labor force is taken into account.

A smaller national population can also have geo-strategic effects, but the correlation between population and power is a tenuous one. Technology and resources often play more significant roles. Since WWII the “static” theory saw a population's absolute size as being one of the components of a country’s national power. More recently, the "human capital" theory has emerged. This view holds that the quality and skill level of a labor force and the technology and resources available to it are more important than simply a nation's population size.

National efforts to reverse declining populations

Many European countries, including France, Italy, Germany and Poland, have offered some combination of bonuses and monthly payments to families.

Paid maternity and paternity leave policies can also be used as an incentive. Sweden built up an extensive welfare state from the 1930s and onward, partly as a consequence of the debate following Crisis in the Population Question, published in 1934. Today, Sweden has extensive parental leave where parents are entitled to share 16 months' paid leave per child, the cost divided between both employer and State.

Many nations that are currently witnessing depopulation with fertility rates below sub-placement (like the west) are recommending quantitative easing to combat deflation, while other economists, such as Paul Krugman, believe governments should prioritize fiscal policy, such as bringing back Keynesian policies.

Alternative concept relative to skills

Sometimes the concept of population decline is applied where there has been considerable emigration of skilled professionals. In such a case, the government may have ceased to reward or value certain skills (e.g. science, medicine and engineering), and sectors of the economy such as health care and technology may go into decline. Such characterizations have been made of Italy, Bulgaria and Russia in the period starting about 1990.
