High Global Population Growth Fears Debunked

Since the 1970s, and earlier with Malthus and eugenics movement, we have been presented with the threat of catastrophic population growth due to fertility rates in the less developed world, then due to 'immigration' from the less developed world when in fact we are facing population decline from mid century; contrary to UN Population Division data which inflates future headline growth?

This 'misunderstanding' has been highlighted by science journalist Fred Pearce in 'The Coming Population Crash: and Our Planet's Surprising Future'; Hans Rosling in 'Don't panic the truth about population'; Prof. Wolfgang Lutz of Vienna's IIASA and Sanjeev Sanyal demographer at Deutsche Bank.


Most assume the world is experiencing exponential population growth due to high fertility but are wrong.

'Book review: 'Empty Planet' explores the world's next biggest population threat

Humanity is facing an imminent catastrophe, Darrell Bricker and John Ibbitson assert in their new book

The central assertion Darrell Bricker and John Ibbitson make in Empty Planet is one that readers of the daily news or regular government reports will find deeply counter intuitive. According to all that received wisdom, there is a worldwide population crisis, with humans reproducing at ever-increasing rates, rapidly eating up all the world’s resources and driving the engines of runaway climate change.

Stripped of modern trappings such as greenhouse gases and industrial meat farming, this is fairly close to the old vision of 18th-century scholar and theorist Thomas Malthus. He declared back in 1798 that in conditions of economic and cultural stability, the human population would continue to increase, even to the point where it chokes resources and overburdens the Earth itself.

Such a view has been the standard for centuries, and some of its proponents have made quite tidy sums writing books about the doom it foretells, most notably Paul Ehrlich. His 1968 bestseller The Population Bomb warned of imminent, widespread famines as the result of human overpopulation.

Bricker and Ibbitson say such books and the thinking behind them are “completely and utterly wrong”. They agree with Malthus, Ehrlich and company that humanity is indeed facing an imminent population catastrophe – but the problem won’t be overpopulation. “The great defining event of the 21st century – one of the great defining events in human history – will occur in three decades, give or take, when the global population begins to decline,” they write. “Once that decline begins, it will never end.”

The authors know they’re working against not only popular perception, but also raw numbers. They point out that the United Nations predicts the human population to hit 11 billion in the 21st century, up from the nearly eight billion on Earth today, an increase from five billion since 1950.

But Bricker and Ibbitson say that population growth rates have declined slightly in the 21st century, particularly in what they refer to as the richest places on the planet. Japan, Korea, Spain, Italy, much of Europe – all such places are facing long-term reproduction rates that won’t come close to sustaining their current population levels. And they claim this same levelling and then downward trend will be seen in places such as China, Brazil, Indonesia and even such fertility hot zones as India and Sub-Saharan Africa.

The main reason Bricker and Ibbitson cite for their certainty about all this is that the floor of the world’s basic prosperity is steadily rising. Two things happen as a result: an increasing number of women in developing countries are gaining more education and more control over reproduction, and an increasing number of couples are therefore either postponing having children of their own or having far fewer children than their ancestors did.

Empty Planet makes the case that this change is not only inevitable but already well under way, and that it will be permanent: humanity will simply go into terminal decline, no asteroid or other global catastrophe required. As mentioned, readers have heard such alarming claims before – Ehrlich, for instance, was certain the human population would reach its breaking point in the 1970s.'

Population Growth or Decline?

Many believe that local, national and global population growth is exponential leading to calls to avoid immigration or cut, need for population control etc., but is it true?  No, according to experts, outside of the UN Population Division, population will peak mid century then decline while ageing further.

What does this mean for the world and nation state economies?  Competition for people whether immigration and temporary workers to fill gaps and support budgets.

From The Lowy Institute:

'Harnessing demographic destiny

GRANT WYETH

Competition for the world’s best and brightest will intensify as global population growth slows. Is Australia ready?

Once confident predictions that the world’s population will reach billion by the end of this century are beginning to be debunked. It is now appears more likely that the global population will hit a ceiling before reaching nine billion by mid-century, and then begin to decline.

This tapering of world population growth is being driven by two key revolutions. One is increasing urbanisation, with more and more people living in cities, which makes children less of an essential resource for families then they would be in rural areas. The other is female education and empowerment, with women deciding – when given the choice – that they desire no more than two children.

Such global trends have significant implications for individual countries, both in national capabilities and geostrategic calculations. This is particularly the case for Australia. Countries that are able to both retain and attract people will find themselves at a distinct advantage.

Currently there is a low-intensity competition for human capital between mostly Western states. These countries have recognised a basic demographic problem; that their birth rates are too low to replace their populations, and without immigration they will end up with elderly societies without the workers to sustain their living standards. Alongside this, attracting highly skilled migrants also boosts productivity.

Yet the population strategies of most of these countries are under threat by parochial narratives that place the political sustainability of their immigration programs at risk.

These narratives are born out of a paradox within the nation-state, where elements within these countries believe that the strategies of the state are undermining the nation. Such sentiment seems uninterested in economic imperatives, or indeed foreign policy concerns about their country’s capabilities in relation to others. Yet these issues are vital to a national interest, and therefore need to be aligned to how a country sees itself….

….. However, it would not be prudent for Australia to rely on this possibility.  By seeking to enhance its own capabilities, Australia can help to escape the influence of external forces. Which means in a world of declining birth rates, Australia’s immigration program should be seen as the country’s principal strategic asset. This indicates that Australia may need to develop something it currently lacks – a prominent positive public narrative around its highly successful immigration story.

A recent speech from Canada’s Conservative Party leader Andrew Scheer offers a good example of the way Australia can develop a positive public narrative around immigration. Scheer highlighted the bravery of migration, the honour Canada feels at being chosen by migrants, and the prosperity that has developed in Canada as a consequence of these migrant flows. It is a speech that no politician in Australia could seemingly deliver (bar its requisite politicking) but is a sentiment that is embraced by all Canadian political parties (with the exception of the Quebec nationalist parties).

As a competitor to Australia for skilled labour, the message Scheer conveyed helps to reinforce support for Canada’s immigration program. And if national competition for people intensifies as global population declines, it will provide Canada with a distinct advantage that Australia currently cannot match.’

Global Population - Fertility Decline

Don’t Panic – Hans Rosling Showing the Facts About Population

The world might not be as bad as you might believe!

“Don’t Panic” is a one-hour long documentary produced by Wingspan Productions and broadcasted on BBC on the 7th of November 2013.

‘With the world’s population at 7 billion and still growing we often look at the future with dread. In Don’t Panic - The Truth About Population, world famous Swedish statistical showman Professor Hans Rosling presents a different view…

… We face huge challenges in terms of food, resources and climate change but at the heart of Rosling’s statistical tour-de-force is the message that the world of tomorrow is a much better place than we might imagine.

Global population growth is set to follow declines in fertility downwards.

Professor Rosling reveals that the global challenge of rapid population growth, the so-called population explosion, has already been overcome. In just 50 years the average number of children born per woman has plummeted from 5 to just 2.5 and is still falling fast. This means that in a few generations’ time, world population growth will level off completely. And in what Rosling calls his ‘Great British Ignorance Survey’ he discovers that people’s perceptions of the world often seem decades out of date.

Highlights from Ignorance survey in the UK

Highlights from the first UK survey re ignorance of global trends. A preliminary summary by Hans Rosling, Gapminder Foundation, 3 Nov, 2013

Gapminder’s mission is to fight devastating ignorance about the world with a fact-based worldview that everyone can understand. We started the Ignorance Project to measure what people know and don´t know about major global trends.

The results indicate that the UK population severely underestimates the progress in education, health and fertility reduction in the world as a whole and in countries like Bangladesh, whereas they severely overestimate how much the richest countries have changed to renewable energy. It is noteworthy that the results from those with university degrees are not better than the average results, if anything they are worse. The results from UK are similar to those obtained by a 2013 survey in Sweden.

The aim of these surveys is to understand how deep and how widespread the public ignorance of major global development trends is in different countries. We are investigating the knowledge about the order of magnitude and speed of change of the most important aspects of the life conditions of the total world population. The first survey covered some major trends in demography, health, education and energy.
  1. In the year 2000 the total number of children (age 0-14) in the world reached 2 billion. How many do UN experts estimate there will be by the year 2100?
  2. What % of adults in the world today are literate, i.e. can read and write?
  3. What is the life expectancy in the world as a whole today?
  4. In the last 30 years the proportion of the World population living in extreme poverty has…
  5. What % of total world energy generated comes from solar and wind power? Is it approximately
  6. What is the life expectancy in Bangladesh today?
  7. How many babies do women have on average in Bangladesh?

Conclusions

Question 1: The answers reveal very deep ignorance about population growth. Only 7% know that the total number of children (below age 15) already has stopped increasing. Almost half of the respondents think there will be twice as many children in the world by the end of the century compared to the forecast of the UN experts.

Questions 2 and 3: Answers show that the respondents think the literacy rate and the life expectancy of the world population is around 50% and 60 years (median values), respectively. But these figures correspond to the how the world was more than 30 years ago.

Question 4: The results show that just 10% are aware of that the United Nations’ first Millennium Development Goal, to halve the world poverty rate, has already been met, even before the target year 2015. More than half think the poverty rate has increased. It is important to understand that random guessing would have yielded 33% correct answers. The result is therefore not due to lack of knowledge, rather it must be due to preconceived ideas. The results strongly indicate that the UK public has failed to be informed about the progress towards the first of the UN´s Millennium Development Goals.

Question 5: Two thirds of the respondents severely overestimate the present role of new renewable sources of energy in world energy production. The present proportion is close to 1%.

Questions 6 and 7: The respondents reveal a deep ignorance about the progress of Bangladesh during the last two to three decades. Only about one in ten know that life expectancy in Bangladesh today is 70 years and that women on average have 2.5 babies.
