S.P.Kapitza: The phenomenological theory of world population growth 3. Modelling world population growth Constructing a model entails the application of methods developed for the study of dynamic systems to data provided poorly by demography and anthropology. These facts and figures are poorly known to physicists and one of the purposes of this paper is of introduce them to a new set of problems. In a number of cases it will be possible to identify concepts and recognise well-known ideas in a new setting. On the other hand it should be kept in mind that both the data and the model itself are but crude images of the real world. In interdisciplinary studies, one of the main difficulties that of taking ideas and methods from one field and transferring them into another. This process is perhaps best developed in mathematics when models are suggested, and then in theoretical physics, although it is difficult to say when a model can reach the status of a theory, serve not as a description of events, but lead to greater insight into the nature of the phenomena treated. For a system as complicated as the population of the world it is this complexity that provides an opportunity. When many factors are relevant and different interactions simultaneously occur, it can be expected that a statistical approach is feasible. In this case, most of the spatial and temporal variations will average out with the consequence that of all the different processes taking place, those finally determining the systemic behaviour are left. Then we can expect to explore the resulting pattern of changes that have an objective nature and can be expressed numerically. The following treatment of the world population is based on the development of such a model [9-12].

World Population Grew by 76 Million People in 2004: 3 Million Added in the Industrial World and 73 Million in the Developing World Janet Larsen During 2004, 133 million people were born and 57 million died, expanding world population by 76 million. This excess of births over deaths was concentrated in the developing countries, which added 73 million people compared with only 3 million in the industrial countries. World population, growing by 1.2 percent annually, is projected to reach 6.4 billion in 2005. (See Figure 1 Six countries account for half the annual increase in population, and all of these but the United States are in the developing world. India accounts for 21 percent of this growth, China 12 percent, Pakistan 5 percent, and Bangladesh, Nigeria, and the United States 4 percent each. It took from the beginning of human existence until early in the nineteenth century for our ranks to grow to 1 billion. We reached the second billion 123 years later, in 1927. Since then, however, the milestones of each new billion have arrived much quicker: world population hit 3 billion in 1960, 4 billion in 1974, 5 billion in 1987, and 6 billion in 1999. We will likely hit 7 billion by 2013. As population grows, the land and water available per person shrinks. For the human population to stabilize, family size needs to fall to an average of two children per couple, known as replacement-level fertility. In 1950, women around the world had on average five children during their lifetimes. Today women in industrial countries give birth to one or two children on average, while those in developing countries have more than three. (See

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.

Jean Pierre Guengant of the French Institute for Research and Development said Tuesday that between 1960 to 1965 and 2000 to 2005, fertility rates declined in Latin America from six children for one woman to 2.9, and in Asia from 5.6 to 2.2 children one mother. But in Africa, the rate fell only from 6.9 to 5.0, said the French expert on the second day of the 25th International Population Congress that will last to July 23 in the French central city of Tours. "In Asia, a strong commitment to family planning programmes is the main reason behind the success of many countries to achieve high levels of contraception," he said.

World Population Trends and Challenges For much of the last half century, public discussion of population issues has focused on the proposition that the world faced a population explosion. Many predicted dire consequences as population growth rapidly used up supplies of exhaustible resources such as metals and petroleum.

G L O B A L I S S U E S Pop ula tion at the Millennium WORLD POPULATION: A MAJOR ISSUE FOR THE MILLENNIUM By Carl Haub G lobal population will hit 6,000 million next year. Five thousand million was reached just 12 years ago, in 1987. That fact alone reminds us that the contemporary explosion in world population is far from over. Where does the world population situation stand and what can we reasonably expect for the future? To consider the first of those questions, we have to rewind the clock a bit, back to the 1960s, when there was no doubt in anyone's mind that world population was indeed exploding. In 1960, global population had just reached 3,000 million. The addition of the third thousand million had taken the remarkably short time of 30 years. Paul Ehrlich's classic book, "The Population Bomb," appeared in 1968, and it opened by asserting that the battle to feed all of humanity had been lost. It is hardly the fashion today to offer any sort of defense of Ehrlich and those seen as the Cassandras of the past, but perhaps it is useful to take a look back and reconsider. Ehrlich's warning helped set the tone for the period. Such concerns were justified in the context of the times. In the 1960s, world population was growing at its fastest pace in history. The developing countries were increasing at the remarkable rate of 2.5 percent per year and they held more than 70 percent of the world total. At such a rate, their numbers would double every 27 years. This was all the more daunting when we realized that it took until 1800 for all of human history to reach the first thousand million and until 1930 to reach the second.

Versions of those prophecies have dominated the environmental debate over the last half century. Now the u-turn. The latest predictions suggest that world population growth is coming to an end. Forecasters say the world's population will peak at about 10 billion later this century, then could even begin to decline. And that creates a looming social problem, one that Australia, as we've heard, is already contemplating, the problem of the aging population.

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.

End of world population growth projected for 21st century November 1996 U.S. Water News Online LUXEMBURG, Austria The world's population, which has quadrupled over the past 80 years, may never double again, according to new population forecasts by the Population, Development and Environment Project at the International Institute for Applied Systems Analysis (IIASA). IIASA is a non-governmental research institution sponsored by a consortium of National Member Organizations in 17 nations. The Institute's research focuses on sustainability and the human dimensions of global change. According to IIASA's projections, there is a 66 percent chance that the world's population will not reach 11.5 billion double today's population within the next century, if ever. The projections reflect the impact of alternative assumptions for birth rates, migration, and death rates. Based on expert opinions, the projections include confidence levels for global populations and go up to the year 2100. The projections, and the assumptions on which they are based, are discussed in the new revised edition of The Future Population of the World: What Can We Assume Today?

Looking Ahead Human Population Growth The Rate of Natural Increase ( r Birth rate ( b d ) = rate of natural increase ( r birth rate expressed as number of births per 1000 per year (currently 14 in the U.S.); death rate expressed as the number of deaths per 1000 per year (currently 8 in the U.S.); So the rate of natural increase is 6 per thousand (0.006 or 0.6%). Although the value of r is affected by both birth rate and death rate, the recent history of the human population has been affected more by declines in death rates than by increases in birth rates. The graph shows birth and death rates in Mexico since 1930. The introduction of public health measures, such as better nutrition greater access to medical care improved sanitation more widespread immunization has produced a rapid decline in death rates, but until recently there was no corresponding decline in birth rates. In 2005, r is 1.9%. (Data from the Population Reference Bureau.) This situation, resulting in a rapid rate of population growth, is characteristic of many of the poorer regions of the world.
