[176] Paul Ehrlich also advocates making "modern contraception and back-up abortion available to all and give women full equal rights, pay and opportunities with men," noting that it could possibly "lead to a low enough total fertility rate that the needed shrinkage of population would follow. Worldometer About FAQ Licensing Newsletter Contact. There is no less than 500,000 White people in Puerto Rico. [44], During the European Agricultural and Industrial Revolutions, the life expectancy of children increased dramatically. View the complete population historical table, View population projections for all years (up to 2100). A tremendous change occurred with the industrial revolution: whereas it had taken all of human history until around 1800 for world population to reach one billion, the second billion was achieved in only 130 years (1930), the third billion in 30 years (1960), the fourth billion in 15 years (1974), and the fifth billion in only 13 years (1987). We are fighting a losing battle, UN admits", "Half of all food 'wasted' report claims", "Oil shock could push world food prices higher", "Global food production will have to increase 70% for additional 2.3 billion people by 2050", "The State of Food Insecurity in the World, 2008: High food prices and food security – threats and opportunities", "One sixth of humanity undernourished – more than ever before", "The biodiversity of species and their rates of extinction, distribution, and protection", "Accelerated modern human–induced species losses: Entering the sixth mass extinction", "Biological annihilation via the ongoing sixth mass extinction signaled by vertebrate population losses and declines", "World Scientists' Warning to Humanity: A Second Notice", "Population explosion fuelling rapid reduction of wildlife on African savannah, study shows", "Human society under urgent threat from loss of Earth's natural life", "Humans exploiting and destroying nature on unprecedented scale – report", "Animal populations worldwide have declined by almost 70% in just 50 years, new report says", "The best way to reduce your carbon footprint is one the government isn't telling you about", "China one-child policy leads to forced abortions, mothers' deaths", "Paul Ehrlich: 'Collapse of civilisation is a near certainty within decades, "Morgan Freeman on the 'Tyranny of Agriculture' and the Doomed Human Race", "Agriculture and Human Population Growth", "Fact or Fiction? Jean-Noël Biraben (1980), "An Essay Concerning Mankind's Evolution". [56][57] After the collapse of the Soviet Union, Russia's population declined significantly – from 150 million in 1991 to 143 million in 2012[58] – but by 2013 this decline appeared to have halted. watch as we increase. [135] The transition from hyperbolic growth to slower rates of growth is related to the demographic transition. Fewer than 15,000 individuals, according to the, An approximation based on figures from different sources as listed at the US Census Bureau's, Some population control programs, such as China's. While just 170 million people … [32] In that year, the population of Western Han was recorded as 57,671,400 individuals in 12,366,470 households, decreasing to 47,566,772 individuals in 9,348,227 households by AD 146, towards the End of the Han Dynasty. During the 20th century alone, the population in the world has grown from 1.65 billion to 6 billion. The InterAcademy Panel Statement on Population Growth, which was ratified by 58 member national academies in 1994, states that "unprecedented" population growth aggravates many environmental problems, including rising levels of atmospheric carbon dioxide, global warming, and pollution. [98], In 2006, the United Nations stated that the rate of population growth was visibly diminishing due to the ongoing global demographic transition. [134] The hyperbolic growth of the world population observed until the 1970s was later correlated to a non-linear second order positive feedback between demographic growth and technological development. "He was making his statement in 1968. Different ethnicities also display varying birth rates. Many scientists think Earth has a maximum carrying capacity of 9 billion to 10 billion people. [53] The population of the United Kingdom reached 60 million in 2006. A number of factors contributed to this increase, including the lessening of the mortality rate in many countries by improved sanitation and medical advances, and a massive increa… In 1968, Paul R. Ehrlich reprised Malthus' argument in The Population Bomb, predicting that mass global famine would occur in the 1970s and 1980s. [42] According to the most extreme scholarly claims, as many as 90% of the Native American population of the New World died of Old World diseases such as smallpox, measles, and influenza. So, let us consider that the "normal" growth was such as to produce only the earth's population as many people have been born into the world as it was at the time of Christ, about 200 million people. Haub also stated that "life expectancy at birth probably averaged only about ten years for most of human history",[184] which is not to be mistaken for the life expectancy after reaching adulthood. [9], Total annual births were highest in the late 1980s at about 139 million,[10] and as of 2011 were expected to remain essentially constant at a level of 135 million,[11] while deaths numbered 56 million per year and were expected to increase to 80 million per year by 2040. [123][124] The 2019 Revision of the UN estimates gives the "medium variant" population as; nearly 8.6 billion in 2030, about 9.7 billion in 2050 and about 10.9 billion in 2100. This is staggeringly incorrect. [34] New crops that were brought to Asia and Europe from the Americas by Portuguese and Spanish colonists in the 16th century are believed to have contributed to population growth. [163][164][165][166] By 2050 population growth, along with profligate consumption, could result in oceans containing more plastic than fish by weight. This feedback can be described as follows: technological advance → increase in the carrying capacity of land for people → demographic growth → more people → more potential inventors → acceleration of technological advance → accelerating growth of the carrying capacity → faster population growth → accelerating growth of the number of potential inventors → faster technological advance → hence, the faster growth of the Earth's carrying capacity for people, and so on. Global population increases by 2.5 people per second • Per minute: 150 people • Per day: 216,000 people • Per Year: 78 million people According to global statistics, the world population on earth increases by 2.5 people every second. The greater number of men is possibly due to the significant sex imbalances evident in the Indian and Chinese populations. Malthus wrote the essay to refute what he considered the unattainable utopian ideas of William Godwin and Marquis de Condorcet, as presented in Political Justice and The Future Progress of the Human Mind. When looking at how many people have smartphones in the world over time, the average global figures have increased to 45.1% at the start of 2020. The United Nations Population Division (UNPD), which keeps track of the world population, projects that the world's human population will hit 7 billion on Halloween Day 2011. The U.S. population clock is based on a series of short-term projections for the resident population of the United States. The question, “how many people can Earth support?” has been asked and answered many times. Cite Warren, Stephen G. "Did agriculture cause the population explosion?." During the 20th century, the global population saw its greatest increase in known history, rising from about 1.6 billion in 1900 to over 6 billion in 2000. Elaboration of data by United Nations, Department of Economic and Social Affairs, Population Division. Gender Populations Across the Globe Gender ratios between men and women vary across the globe for numerous reasons. [16], Estimates of world population by their nature are an aspect of modernity, possible only since the Age of Discovery. [155] In 2009, the UK government's chief scientific advisor, Professor John Beddington, warned that growing populations, falling energy reserves and food shortages would create a "perfect storm" of shortages of food, water, and energy by 2030. The points at which it reached three and four billion were not officially noted, but the International Database of the United States Census Bureau placed them in July 1959 and April 1974 respectively. The world population counter displayed on Worldometer takes into consideration data from two major sources: the United Nations and the U.S. Census Bureau. [158] The 2009 FAO estimates showed an even more dramatic increase, to 1.02 billion. How many people speak English? Population size fluctuates at differing rates in differing regions. when the ancestors of Homo sapiens appeared, or several million years ago when hominids were present), taking into account that all population data are a rough estimate, and assuming a constant growth rate applied to each period up to modern times, it has been estimated that a total of approximately 106 billion people have been born since the dawn of the human species, making the population currently alive roughly 6% of all people who have ever lived on planet Earth. Pick a number", "The Story Of... Smallpox – and other Deadly Eurasian Germs", "By 2050, 70% of the world's population will be urban. The above world population clock is based on the latest estimates released in June of 2019 by the United Nations and will show the same number wherever you are in the world and whatever time you set on your PC. It states that the people alive today outnumber those who have ever lived and died throughout human history. The population debate: Are there too many people on the planet? The period encompasses the first 10,000 years of human's foray into the world. Is that a good thing? [103], During the 2010s, Japan and some countries in Europe began to encounter negative population growth (i.e. [43] Over the centuries, the Europeans had developed high degrees of immunity to these diseases, while the indigenous peoples had no such immunity. [81], The CIA estimated nominal 2013 gross world product at US$74.31 trillion, giving an annual global per capita figure of around US$10,500. The world's two most populated countries, China and India, together constitute about 36% of the world's population. The shaded regions correspond to the range of projections by the United Nations Department of Economic and Social Affairs. Resource demands are expected to ease as population growth declines, but it is unclear whether mass food wastage and rising living standards in developing countries will once again create resource shortages. [21], It is difficult for estimates to be better than rough approximations, as even modern population estimates are fraught with uncertainties on the order of 3% to 5%. The pre-agrarian period refers to the era when humans were starting to make their way up the pyramid of life. [52] Improved material conditions led to the population of Britain increasing from 10 million to 40 million in the 19th century. Others have estimated the number of human beings who have ever lived to be anywhere from 45 billion to 125 billion, with most estimates falling into the range of 90 to 110 billion humans. A number of factors contributed to this increase, including the lessening of the mortality rate in many countries by improved sanitation and medical advances, and a massive increase in agricultural productivity attributed to the Green Revolution. [84] 83% of the world's over-15s are considered literate. The use of abortion in some population control strategies has caused controversy,[173] with religious organizations such as the Roman Catholic Church explicitly opposing any intervention in the human reproductive process. Nonetheless, population growth is the long-standing trend on all inhabited continents, as well as in most individual states. The following table gives estimates, in millions, of population in the past. It has been undertaken as a response to factors including high or increasing levels of poverty, environmental concerns, and religious reasons. [119] The UN has issued multiple projections of future world population, based on different assumptions. The rate of increase has nearly halved since then, and will continue to decline in the coming years. This figure is up from 33.5% back in 2016, a substantial increase in a few short years. Just 10,000 years ago there might have been no more than a … [48][49] Between 1700 and 1900, Europe's population increased from about 100 million to over 400 million. It implies per minute: 150 people. By contrast, it is estimated that around 50–60 million people lived in the combined eastern and western Roman Empire in the 4th century AD. All on this page, one by one. China's population rose from approximately 430 million in 1850 to 580 million in 1953,[60] and now stands at over 1.3 billion. Such estimates can only be rough approximations; as even modern population estimates are subject to uncertainty of around 3% to 5%. Between 1950 and 1984, as the Green Revolution transformed agriculture around the world, grain production increased by over 250%. The tables below list the world's most densely populated countries, both in absolute terms and in comparison to their total populations. Figures include the former Soviet countries in Europe. [22] Kapitza (1996) cites estimates ranging between 80 and 150 billion. [130], Scientists contend that human overpopulation, continued human population growth and overconsumption, particularly by the wealthy, are the primary drivers of mass species extinction.

The median age of the world's population was estimated to be 30.4 years in 2018. This increase appears to be extraordinary. Average global birth rates are declining fast, but vary greatly between developed countries (where birth rates are often at or below replacement levels) and developing countries (where birth rates typically remain high). [35][36][37] Since their introduction to Africa by Portuguese traders in the 16th century,[38] maize and cassava have similarly replaced traditional African crops as the most important staple food crops grown on the continent. September 11, 2019. With seven billion people on Earth, pollution from industry and cars is a growing element in climate change — which affects our planet in ways we can’t predict. One characteristic feature of exponential growth is the time a population takes to double in size. [142], In 2004, a meta-analysis of 70 quantitative studies estimating a sustainable limit to the world population generated a meta-estimate of 7.7 billion people. This statistic shows the most spoken languages in the world. Check out this simple wizard or this more elaborated one to find out. [77] In June 2014, there were around 3.03 billion global Internet users, constituting 42.3% of the world population. [127] Some analysts have questioned the sustainability of further world population growth, highlighting the growing pressures on the environment,[128] global food supplies, and energy resources.[129][130][131]. [120][121] 2003 UN Population Division population projections for the year 2150 range between 3.2 and 24.8 billion. [5], The world population has experienced continuous growth following the Great Famine of 1315–1317 and the end of the Black Death in 1350, when it was near 370 million. Approximately 4.45 billion people live in these ten countries, representing around 57% of the world's population as of September 2020. But once an estimate is made (based on the best data and analysis available), the world population clock should be showing the same number at any given time anywhere around the world. [72] Projected figures vary depending on underlying statistical assumptions and the variables used in projection calculations, especially the fertility variable. Ehrlich places the optimum global population size at 1.5 to 2 billion people. [160][161] On this page you can see every single one of us. [67] Thereafter, the global population reached four billion in 1974, five billion in 1987, six billion in 1999 and, according to the United States Census Bureau, seven billion in March 2012. [41] Encounters between European explorers and populations in the rest of the world often introduced local epidemics of extraordinary virulence. [69][70][71], According to current projections, the global population will reach eight billion by 2024, and is likely to reach around nine billion by 2042. The world population has grown rapidly, particularly over the past century: in 1900 there were fewer than 2 billion people on the planet; today there are 7.7 billion.. Approximately 83 million people are born each year. [182] Haub (1995) prepared another figure, updated in 2002 and 2011; the 2011 figure was approximately 107 billion. [99][100][101], In 2000, the United Nations estimated that the world's population was growing at an annual rate of 1.1% (equivalent to around 75 million people),[102] down from a peak of 88 million per year in 1989. The highest global population growth rates, with increases of over 1.8% per year, occurred between 1955 and 1975 – peaking at 2.1% between 1965 and 1970.
