Chapter 1 World Population: Major Trends Figure C1_1 Table C1_1 World population will grow significantly - despite falling fertility. There is a most striking paradox in global population trends: on one hand we have had a rapid decline in fertility for over two decades in many developing countries - not to mention the already very low fertility in most of the highly developed nations; on the other hand we will almost certainly experience a further massive increase of the world population. In their most recent projection ("World Population Assessment and Projection. The 1996 edition") the United Nations Population Division projects a global population of 8.04 billion for the year 2025 and 9.37 billion for 2050 (see Figure C1_1 and Table C1_1). According to this medium variant , an increase of some 2.35 billion people can be expected worldwide between 1995 and 2025; and an additional 1.3 billion between 2025 and 2050. These numbers are a little smaller than previous UN estimates, leading some mass media to jump to the conclusion that world population growth will be over soon. This rash judgment might be premature. This UN medium variant projection is based on the assumption that almost all

UN demographers also predict that fertility in most of the developing world will fall below the replacement level (2.1 children per woman) before the end of the 21st century. Factors leading to falling birth rates include increased level education for women, the use of contraceptives, and urbanization. 20 less developed countries where fertility is at or below replacement levels Armenia, Barbados, Chile, China, Cuba, Cyprus, Georgia, Guadeloupe, Hong Kong, Iran, Kazakhstan, Macao, Martinique, North Korea, Puerto Rico, Saint Lucia, Singapore, Thailand, Trinidad and Tobago.

WASHINGTON - Fewer births and more deaths from AIDS are helping slow world population growth, the Census Bureau says. In a report Monday, the bureau forecast a world population of about 9.1 billion people by 2050, a nearly 50 percent increase from the 6.2 billion in 2002. However, the growth rate is slowing significantly. The global population grew 1.2 percent from 2001 to 2002, or about 74 million people, but growth will slow to 0.42 percent by 2050. That's far below the peak growth of 2.2 percent between 1963 and 1964. The projections are generally in line with separate forecasts from the United Nations and private researchers. The 2050 world projection is slightly lower than the 9.3 billion forecast in a previous bureau report on the topic in 1998. Bureau officials warned that such forecasts are based on two factors that could change: fertility rates in developing countries and the AIDS epidemic.

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 following table lists some of those estimates, based in part on data considered "most reliable" in a 1970 paper and in part on both overlapping and more recent data from the U. S. Census Bureau . Of course, the earliest entries are at best educated guesses. The later entries are more likely to be correct at least to have the right order of magnitude but you should be aware that there is no "world census" like the decennial U.

BILLIONS AND BILLIONS AND BILLIONS When we talk about world population growth statistics, we get into very large numbers with many confusing zeroes at the end. While lots of 0's may bring back fond memories of our days of test scores and playing hooky from school, they do nothing to help us understand a factual sentence like: "The earth's population is projected to rise from 6,400,000,000 in 2004 to 8,900,000,000 in 2050." That means we will likely increase world population by 2.5 billion people in the next half-century, but how do we put such a large number in context to make it easier to grasp? Does population growth just mean a few more people at the next block party, or will the teeming masses start falling off the edge of whatever cliff they're closest to? In this article, we'll try to make sense of world population growth statistics, and then we'll discuss why this increase in global population is significant.

Home Overpopulation: An Introduction to the Issues Population Growth: 1960-2000 Overpopulation.Com Guests Logon Account Signup Links Population Growth: 1960-2000 Those predicting an overpopulation disaster were right about one thing – the world’s population increased substantially over the last 40 years. In 1970, world population was about 3.7 billion. By the year 2000, world population will top 6 billion – an increase of 62 percent. Although the total world population continues to increase, the rate that the world’s population is growing began declining in the 1970s. The table below shows how fast world population grew for each decade beginning in the 1960s: Year Percentage increase in world population The rate of world population growth peaked in the 1970s and has been falling ever since. In fact the decline accelerated dramatically in the 1990s. Why is the population falling now? Largely because women are choosing to have fewer children. Trends in child birth rates are usually tracked by following the total fertility rate Why did the total fertility rates fall? At the moment there is no consensus on this question. Among the various proposed reasons are: increased economic opportunity; increased educational opportunity; women’s expanding access to family planning resources; cultural changes within societies. Studying human societies and finding one or two causes is probably doomed to fail – ultimately fertility declined because women and men chose to have fewer children and simplifying those individual decisions to form a simple theory is unlikely to prove fruitful.

World Population Growth. Population growth is basic to any environmental issue. Humans exert a profound physical impact on their immediate, regional and global environment. Space considerations We take up space that was once forest, wetland, prairie or mountainside. While the space taken up by each individual varies. For example, it can be minimal such as in the cities of India or considerable such as in the late 1990 American single-family home which averages 2100 ft (0.05 acres or 0.02 hectares). Food considerations We need to eat so land is required for agriculture. Much of that land is irrigated and fertilized with industrially produced fertilizers. Meat production produces animal wastes that can result in water pollution via runoff. Transportation Roads cover permeable land with impervious paving and generate polluted runoff. They impact animals by dividing animals habitats which may accelerate species loss. Roads also provide human access to wilderness and forestland resulting in alterations of these areas. Waste Production People in developed countries produce huge amounts of sewage as well as commercial, residential and industrial wastes. In the U.S. alone each individual produces about 725 Kg of municipal waste each year (exclusive of mining and other industrial waste.)

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.

Barbara Crosette, "Experts Scale Back Estimates of World Population Growth," New York Times , 20 August 2002 Demography has never been an exact science. Ever since social thinkers began trying to predict the pace of population growth a century or two ago, the people being counted have been surprising the experts and confounding projections. Today, it is happening again as stunned demographers watch birthrates plunge in ways they never expected. A few decades ago in certain countries like Brazil, Egypt, India and Mexico fertility rates were as high as five or six. As a result, United Nations demographers who once predicted the earth's population would peak at 12 billion over the next century or two are scaling back their estimates. Instead, they cautiously predict, the world's population will peak at 10 billion before 2200, when it may begin declining. Some experts are wary of too much optimism, however. At the Population Council, an independent research organization in New York, Dr. John Bongaarts has studied population declines in various countries over the last half century. He questions the assumption that when fertility declines begin they will continue to go down at the same pace, especially if good family planning services are not widely available. Sharp fertility declines in many industrialized and middle-income countries had already challenged another old belief: that culture and religion would thwart efforts to cut fertility. In Italy, a Roman Catholic country whose big families were the stuff of cinema, family size is shrinking faster than anywhere else in Europe, and the population is aging rapidly as fewer children are born. Islamic Iran has also had great success with family planning.
