Has the world's population distribution changed much over time? find out answer In 2000, the world had 6.1 billion human inhabitants. This number could rise to more than 9 billion in the next 50 years. For the last 50 years, world population multiplied more rapidly than ever before, and more rapidly than it will ever grow in the future. Anthropologists believe the human species dates back at least 3 million years. For most of our history, these distant ancestors lived a precarious existence as hunters and gatherers. This way of life kept their total numbers small, probably less than 10 million. However, as agriculture was introduced, communities evolved that could support more people. World population expanded to about 300 million by A.D. 1 and continued to grow at a moderate rate. But after the start of the Industrial Revolution in the 18th century, living standards rose and widespread famines and epidemics diminished in some regions. Population growth accelerated. The population climbed to about 760 million in 1750 and reached 1 billion around 1800 (see chart, "World population growth, 1750–2150,").

Report: World population growth eases 'We're not out of the woods' December 27, 1996 Web posted at: 8:10 p.m. EST (0110 GMT) WASHINGTON (CNN) World population is growing more slowly than in recent years and with a concerted effort to defuse a "demographic time bomb," population could stabilize at 8 billion by 2025, an advocacy group said Friday. Werner Fornos, president of the Washington-based Population Institute, said the world's population is growing by almost 90 million annually, more slowly than the 100-million-person growth of recent years. While he described the reduced rate of growth as an encouraging trend, population growth is still too high for the planet to support. "That's analogous to a tidal wave hitting any one of our coastal cities at 90 feet rather than 100 feet," Fornos said. "So we're not out of the woods. But it is a turnaround and spells for the future much promise." The world's population is nearing 5.9 billion, and will be over 6 billion by the year 2000. But he said it was "a dream and a possibility" to stabilize the population at 8 billion by 2025 "if we keep doing what works." Fornos attributed the recent slowing of the growth rate partly to better education and opportunities for girls and women.

Press Release POP/815 FUTURE WORLD POPULATION GROWTH TO BE CONCENTRATED IN URBAN AREAS OF WORLD According to New Report Issued by United Nations Population Division New York These findings are from just-released United Nations official estimates and projections of urban, rural and city populations, prepared by the Population Division of the Department of Economic and Social Affairs. Major findings of the study "World Urbanization Prospects:  The 2001 Revision" are: Half the world population is expected to live in urban areas in 2007 5 billion by 2030.  Whereas 30 per cent of the world population lived in urban areas in 1950, the proportion of urban dwellers rose to 47 per cent by 2000 and is projected to attain 60 per cent by 2030. Almost all of the population increase expected during 2000-2030 will be absorbed by the urban areas of the less developed regions .  During that period the urban population of the less developed regions is expected to increase by 2.0 billion persons, nearly as much as will be added to the world population, 2.2 billion.

Global Issues >> Population Population Attitudes About World Population Growth An overwhelming majority correctly perceives the world's population as growing and believes that world population growth is a significant problem. However, this majority is divided as to how pressing this problem is-both as a general matter and in terms of security and environmental concerns. An overwhelming majority correctly perceives the world population as growing. In a September 1998 Belden and Russonello poll, 83% described population as growing while only 16% said it was stable (13%) or shrinking (3%). (Only 1% said they did not know-unusually low for a poll question that quizzes respondents on their knowledge. These responses were almost exactly the same to the same question in a 1994 poll.) [ ] The median estimate of world population was fairly accurate, but the median estimate of the rate of population growth was exaggerated. [ An overwhelming majority views overpopulation as a significant problem, but this majority is divided as to how pressing this problem is. This pattern came up in several polls. Eighty-eight percent said in an October 1999 Gallup poll that "population growth internationally" was or would be a problem, while only 11% said they "don't expect it to become a problem." However the 88% was divided between those who said it was "a major problem now" (47%) and those who characterized it as "not a problem now, but likely to become a problem for the future" (41%).[

World Population Growth 1997 Ms Holly In this world many many problems are caused by not having enough... Not enough time, Not enough space, Not enough sleep, Not enough food, Not enough room, Not enough of anything... If you have room for only two people to live in a small house and they have six to seven children - (as they do in many many poorer countries where they have so many problems often they do not have the ability to choose how many children they have) - You will end up being crowded. If you only have enough food for two people that means that those two people have to share that food between themselves and six to seven children when they are born....In these countries often the children starve and die...and suffer greatly....In these countries often there are great wars and plagues because there is not enough - because there are too many children being born because they cannot afford to stop all these children from being born - because they do not have the means or education to do so... Those of us who go to bed every night with food, and shelter... because our system has provided for us to be able to choose how many children we want to have or not have. We have the things we have because we choose how many children we have. But in poorer countries they cannot do that...for many do not have the benefits of good food, shelter, and and education such that they can learn how to stop having too many children...

Craighead Environmental Research Institute The mission of the Institute is to increase humankind's understanding, appreciation, and protection of our natural environment; particularly wildlife populations and wild landscapes. Our goal is to enable human beings to live in harmony with other species. The Problem: World Population Growth The Solution One obvious solution is to reduce the number of human beings to levels at which all can enjoy a high quality of life without endangering other species. This is clearly not going to happen overnight (at least not in any humane fashion). Another possible solution is to develop sustainable economies and to maintain large areas of natural habitat in order to provide ecosystem functions and provide space for other species. This is the approach we are working toward at CERI. (World Population Odometer applet courtesy of Michael Gilpin) For problems or questions regarding this website contact ursus@grizzlybear.org

The End of World Population Growth Will world population grow to double its present size by 2050? Will growth slow down and stop soon? With the personal computer we can narrow the likely trajectory of future world population growth far more than ever before possible. Before the PC, the necessary calculations were too tedious. So demographers prepared widely different projections. United Nations long range projections . . . United Nations long range projections include a "high variant" that has world population growing to 28 billion by the year 2150, a "medium variant" that has growth levelling off at 11.5 billion around 2075, and a "low variant" that has world population growth ending at 7 billion around 2050 followed by population decrease. If it were a weather forecast . . . A weather forecast like that would have us preparing for a blizzard, rain, and a hot dry spell all at the same time. Which is most likely? The medium variant is usually considered the most likely because it is in the middle. But there is another method for finding the most likely path of future world population growth.

Tallying Tomorrow's Consumers: World Population Growth Sets a Slower Pace For U.S. agriculture, global population growth is both a source of confidence in long-term trade prospects, and a source of concern about future world food security. How fast is population growing? According to the U.S. Census Bureau's latest estimates, the global head count (now near 5.9 billion) is increasing at a rate of 8,900 people an hour, nearly 214,000 a day and 78 million this year. World population reached the 3-billion mark in 1959, 4 billion in 1974 and 5 billion in 1987. It is currently projected to top 6 billion in 1999, 7 billion in 2012, 8 billion in 2026 and 9 billion around 2043. Although their underlying assumptions could change, Census Bureau demographers see world population totaling roughly 9.3 billion by the middle of the next century, given present trends. Population growth continues, but at a slowing rate. Current trends suggest a net increase of about 3.2 billion people between 2000 and 2050a lot of new mouths to feed, but less than the 3.5-billion increase from 1950 to 2000. Expressed in percentages, the difference is dramatic: a projected gain of slightly over 50 percent in the first half of the next century, compared with 138 percent over the last half-century. Annual population growth, which averaged 2 percent in the 1960s, is now near 1.3 percent and could drop below 1 percent after 2015. If the slowing continues, global population may approach the replacement rate, or zero net growth, by the end of the 21st century. Had the high growth rates of the 1960s persisted, population already would top 6 billion and would be climbing toward more than 18 billion by 2050.

National Security Study Memorandum 200: World Population Growth And U.S. Security delineates the development and major findings of this important study. Author Stephen D. Mumford reveals: In March, 1970, the U.S. Congress created The Commission on Population Growth and the American Future, which completed its work in March 1972. Its final report offered more than 70 recommendations. Collectively, they constituted a detailed blueprint for a superb national population policy. And uncovers why this commission's final report was ignored. In the words of a Commission member, Congressman James Scheuer (D.-NY): "The reasons were obvious the fear of attacks from the far right and from the Roman Catholic Church because of our positions on family planning and abortion. With the benefit of hindsight, it is now clear that this obstruction was the first of many similar actions to come from high places." Then he goes on to describe the commissioning of the NSSM 200 study, its major findings and the Vatican s responsibility in the failure to implement the study s recommendations.
