  However, there were important regional variations within the general population increase. Broadly speaking, the industrialized nations of Europe and North America had their most rapid increase before the First World War; after that their rate of increase slowed considerably. In the less developed, or Third World nations of Africa, Asia and Latin America, the rate of population increase accelerated after the Second World War, and it was in these areas that population growth caused the most serious problems. The growth rate began to slow down in some Latin American countries after 1950, but in Asia and Africa the rate continued to increase. Figure 28.2, which is based on statistics provided by the United Nations, shows:

  The percentage rates at which the world’s population grew between 1650 and 1959.

  (b) Reasons for the population increase

  The population increase in Europe and North America in the later part of the nineteenth and the early twentieth centuries had several causes.

  Increasing industrialization, economic growth and prosperity meant that the necessary resources were available to sustain a larger population, and the two seemed to go hand in hand.

  There was a great improvement in public health, thanks to advances in medical science and sanitation. The work of Louis Pasteur and Joseph Lister in the 1860s on germs and antiseptic techniques helped to reduce the death rate. At the same time, the big industrial cities introduced piped water supplies and drainage schemes, which all helped to reduce disease.

  There was a decline in infant mortality (the number of babies who died before the age of 1). Again this was mainly thanks to medical improvements, which helped to reduce deaths from diseases such as scarlet fever, diphtheria and whooping cough, which were so dangerous to young babies. The improvement in some countries can be seen in Table 28.1, which shows how many babies per thousand born, died within their first year.

  Immigration helped to swell the population of the USA and, to a lesser extent, some other countries on the continents of America, such as Canada, Argentina and Brazil. In the 100 years after 1820, some 35 million people entered the USA; in the last few years before 1914 they were arriving at a rate of a million a year (see Section 22.2).

  After 1900 the growth rate in Europe began to slow down, mainly because more people were using modern contraceptive techniques. Later, the economic depression of the 1930s discouraged people from having as many children.

  The rapid population growth after 1945 in Third World countries had three main causes:

  Modern medical and hygiene techniques began to make an impact for the first time; the child mortality rate fell and people lived longer, as killer diseases like smallpox, malaria and typhoid were gradually brought under control.

  At the same time, the vast majority of the population made no attempt to limit their families by using contraceptives. This was partly through ignorance and partly because contraceptives were too expensive for ordinary people to buy. The Roman Catholic Church said that contraception was forbidden for its members, on the grounds that it prevented the natural creation of new lives, and was therefore sinful. Since the Roman Catholic Church was strong in Central and South America, its teaching had important effects. The population growth rate for many countries in these areas was over 3 per cent per annum. The average for the whole of Latin America was 2.4 per cent in 1960, whereas the average for Europe was only 0.75 per cent. An increase of 2 per cent per annum means that the population of that country doubles in about 30 years. This happened in Brazil and Mexico in the 30 years up to 1960.

  Many Third World countries have a long tradition of people having as many children as possible to combat high infant mortality, in order to make sure their family continues. Some cultures, Muslims, for example, attach great value to having many sons. The same attitudes persisted in spite of the reduction in infant mortality.

  28.2 CONSEQUENCES OF THE POPULATION EXPLOSION

  (a) The industrializing nations of Europe and North America

  The population growth of the nineteenth century helped to stimulate further economic development. There was a plentiful workforce and more people to buy goods, and this encouraged more investment and enterprise. Nor were there any great problems about feeding and educating these growing numbers, because prosperity meant that the necessary resources were available. Later on, there were unexpected effects on the age structure of the population in the developed nations. This was especially true in Europe where, because of the very low birth rates and longer life expectancy, a growing proportion of the population was over 65. By the 1970s, in countries such as Sweden, France and Britain, about 15 per cent of the population were over 65. In the early 1990s, with this proportion still increasing, questions were being asked about whether state welfare systems would be able to afford to pay pensions to all old people if this trend continued into the twenty-first century.

  (b) The Third World

  The rapid population growth caused serious problems: some countries, like India, Pakistan and Bangladesh, became overcrowded and there was insufficient land to go round. This forced people to move into towns and cities, but these were already overcrowded and there were not enough houses or jobs for all the new arrivals. Many people were forced to live on the streets; some cities, especially those in Latin America, were surrounded by shanty-towns and slums which had no proper water supply, sanitation or lighting.

  (c) It became increasingly difficult to feed the population

  All areas of the world succeeded in increasing their food production during the late 1960s and 1970s, thanks to what became known as the ‘green revolution’. Scientists developed new strains of heavy-cropping rice and wheat on short, fast-growing stems, helped by fertilizers and irrigation schemes. For a time, food supplies seemed to be well ahead of population growth; even a densely populated country like India was able to export food, and China became self-sufficient. In the USA crop yields increased threefold between 1945 and 1995, and the Americans were able to export surplus crops to over a hundred countries. However, in the mid-1980s, with the world’s population growing faster than ever, the ‘green revolution’ was running into problems and scientists became concerned about the future.

  A point had been reached beyond which crop yields could not be increased any further, and there was a limit to the water supply, topsoil and phosphates for fertilizers (see Section 27.4(a)).

  A survey carried out by scientists at Stanford University (California) in 1996 found that the amount of farmland available was dwindling because of industrialization, the spread of cities and soil erosion. They calculated that the number of mouths to feed in the USA would double by 2050.

  There seemed no way in which food production could be doubled from less land. In 1996, on average there were 1.8 acres of cropland to each American and the US diet was made up of 31 per cent animal products. By 2050 there was likely to be only 0.6 of an acre per head. The Stanford scientists came to the conclusion that the solution was for people everywhere to eat less meat; it was suggested that by 2050 the US diet would probably be about 85 per cent vegetarian. Matters were made worse in parts of Africa (Ethiopia, Angola, Mozambique and Somalia) during the 1980s and 1990s by drought and civil wars, which played a part in causing severe food shortages and tens of thousands of deaths from starvation.

  (d) Resource shortages in the Third World

  Third World governments were forced to spend their valuable cash to feed, house, and educate their growing populations. But this used up resources which they would have preferred to spend on industrializing and modernizing their countries, and so their economic development was delayed. The general shortage of resources meant that the poorest countries also lacked suffic
ient cash to spend on healthcare. Following a meningitis epidemic in the African state of Niger, Save the Children reported (April 1996) that one-sixth of the world’s population – over 800 million people – had no access to health-care. Health systems in many poorer countries were collapsing, and the situation was becoming worse because richer countries were reducing aid. The report estimated that it cost at least $12 a person a year to provide basic healthcare; but 16 African countries (including Niger, Uganda, Zaire, Tanzania, Mozambique and Liberia) plus Bangladesh, India, Pakistan, Nepal and Vietnam were spending much less than that. In comparison, Britain was spending the equivalent of $1039 (£723). In fact Zaire was spending only 40c per head a year, while Tanzania managed 70c. This meant that simple immunization against easily preventable diseases was not being carried out in these countries. Widespread epidemics could be expected before the end of the century, and a rise in the child mortality rate. When the AIDS epidemic spread, around the turn of the century, it was clear that Africa in particular would be in dire crisis. Another disturbing fact was that almost all these states were spending vastly more per head on defence than on healthcare.

  28.3 ATTEMPTS AT POPULATION CONTROL

  For many years people had been giving serious thought to the question of controlling the population before the world became too overcrowded and impossible to live in. Soon after the First World War, scientists in a number of countries first began to be concerned at the population growth and felt that it was a problem that should be studied at international level. The first World Population Congress was held in Geneva in 1925, and the following year an International Union for the Scientific Study of Population was set up in Paris. As well as scientists, the organization also included statisticians and social scientists who were concerned about the probable economic and social effects if the world’s population continued to grow. They did valuable work collecting statistics and encouraging governments to improve their data systems, so that accurate information about population trends could be collected.

  (a) The United Nations Population Commission

  When the United Nations Organization was set up in 1945, a Population Commission was included among its many agencies. When the Third World population began to ‘explode’ during the 1950s, it was the UN which took the lead in encouraging governments to introduce birth-control programmes. India and Pakistan set up family-planning clinics to advise people about the various methods of birth control available, and to provide them with cheap contraceptives. Huge publicity campaigns were launched with government posters recommending a maximum of three children per family (see Illus. 28.1). Many African governments recommended a maximum of three children, while the Chinese government went further and fixed the legal maximum at two children per family. But progress was very slow: ancient practices and attitudes were difficult to change, especially in countries like India and Pakistan. In the Roman Catholic countries of South America, the Church continued to forbid artificial birth control.

  (b) How successful were the campaigns?

  The best that can be said is that in parts of Asia the population growth rate was beginning to fall slightly during the 1980s; but in many African and Latin American countries it was still rising. Table 28.2 shows what could be achieved with the spread of birth control.

  Table 28.3 shows the 1986 populations and growth rates of various regions, compared with the 1950–9 growth rates. The most rapid growth rate in 1986 was in Africa, where some countries had rates of over 3 per cent per year. The table also reveals how serious the problem of overcrowding was in some areas where there were on average over a hundred people to every square kilometre. This was not so serious in the developed nations of Europe, which had the prosperity and resources to support their populations; but in the poorer nations of Asia, it meant grinding poverty. Bangladesh was probably the world’s most crowded country with an average of 700 people to every square kilometre. The population growth rates of Bangladesh and Britain provide a startling comparison: at the present growth rates, Bangladesh will double its population of 125 million in less than 30 years, but Britain’s population of 58.6 million will take 385 years to double in size. The Population Institute predicted (December 1995) that, with effective birth control, the global population could stabilize by 2015 at about 8 billion. However, without effective promotion of family planning, the total could well have reached 14 billion by 2050. With the population of Europe and North America growing so slowly, it meant that an ever-increasing proportion of the world’s population would be poor.

  On the other hand, some historians feel that the fears about the population explosion have been exaggerated. Paul Johnson, for example, believes that there is no need to panic; once Asia, Latin America and Africa become more successfully industrialized, living standards will rise, and this economic betterment, along with more effective use of contraception, will slow down the birth rate. According to Johnson, the example of China is most encouraging: ‘The most important news during the 1980s, perhaps, was that the population of China appeared virtually to have stabilised.’

  However, the case of China raises another issue: how far should a government go in its efforts to control population? In 1978 a group of scientists calculated that unless Chinese women were limited to one child each, China would face disaster – the country’s resources would simply not be sufficient to feed the population. Conversely, if the one woman one-child limit could be achieved, then the Chinese would become prosperous and assume their rightful place among the world’s leading nations. In 1980 the government duly announced the one-child policy. Historian Matthew Connelly describes what happened next:

  This was the most coercive phase in the whole history of China’s one-child policy. … All women with one child were to be inserted with a stainless steel, tamper-resistant IUD [intra-uterine device], all parents with two or more children were to be sterilized, and all unauthorized pregnancies terminated. There was not even a pro forma injunction to avoid coercion. … In 1983 more than 16 million women and more than 4 million men were sterilized in China, nearly 18 million women were inserted with IUDs, and over 14 million underwent abortions.

  There was widespread criticism of this policy in China itself. The All-China Women’s Federation demanded an end to ‘infanticide and the abuse of women’. There was outrage among Roman Catholics and pro-life supporters around the world, especially in the USA. Eventually the Chinese government softened the policy, but claimed that it had been successful, and was therefore justified. Now that China’s population has stabilized and the birth rate is even falling, this means that there are fewer people to share the available resources; therefore standards of living should rise and poverty should be reduced. However, some observers point out that although this in itself is a great achievement, it does not solve the problems facing the ecosystem. Matthew Connelly explains why, using as an example some Asian countries which adopted population control policies:

  If Asians have only 2.1 children, but also air conditioning and automobiles, they will have a greater impact on the global ecosystem than a billion more subsistence farmers … [because] they tend to consume more of everything per capita, whether fuel, or water, or wide open spaces.


  This was borne out in a joint report by a group of scientists from 105 institutions published shortly before the Earth Summit Conference of July 2012. This confirmed that one of the main causes of the rapid rise in consumption was ‘the growing middle class in developed countries and the very lavish lifestyles of the very rich across the planet’. American biologist Paul Ehrlich put it this way: ‘The current redistribution of wealth from poor to rich must be halted, and overconsumption by the rich must be controlled with programs such as those that transformed consumption patterns in the United States when it entered World War II.’ Former World Bank economist Aklog Birara suggested that

  the world can no longer afford to follow the same economic and social model of insatiable demand and concentration of consumption and wealth in a few hands. I cannot imagine that the rest of the world would tolerate continuation of 20 per cent of humanity consuming 80 per cent of the world’s goods and services, while one-fifth of the poorest consume only 1.3 per cent. Is this not what triggered the Arab Spring and is likely to trigger Springs in the rest of the poorest and most repressed countries?

  This last point was taken up by Paul Liotta and James Miskel, who highlight another worrying aspect of the still growing population; the growth of huge cities with populations of over 10 million. They calculate that by 2025 there will be at least 27 of these mega-cities around the globe. In Africa, Asia, the Middle East and South America these massive concentrations of people inevitably include a large proportion of poverty-stricken have-nots. In the authors’ words: ‘Crowded masses within these unaccommodating spaces will have literally nowhere else to go; if left to their own devices by inept or uncaring governments, collective rage, despair and hunger will inevitably erupt.’ They argue that mega-cities are attracting terrorists and various types of criminal gangs; unless governments meet this challenge by taking effective counter-measures, some of them will present a serious security threat to the rest of the world.
