The Economic Crisis of Greying World: 30 Countries have more Elderly than Children

By Joseph Chamie | (Inter Press Service) | – –

NEW YORK (IPS) – It first happened in Italy in 1995. Five years later it happened in six additional countries, Bulgaria, Germany, Greece, Japan, Portugal and Spain. Today the total number of countries where it has occurred stands at 30, including most members of the European Union. In fifteen years that number is expected to nearly double and include Australia, Canada, China, Russia, South Korea and the United States (Table 1).

What happened to those countries – and will continue to occur to virtually every country’s population worldwide – is the Historic Reversal or the demographic turning point when children in a population become fewer than its elderly. This noteworthy milestone reflects the significant and far-reaching aging transformation of human populations taking place largely during the 21st century.

Throughout human history children were substantially more numerous than the elderly. Even a half century ago, the world’s population of 3.3 billion had on average more than seven children under 15 years of age for each elderly person aged 65 and over. Africa’s population in 1965 topped other major regions with more than 14 children per elderly person, followed by Asia and Latin America with more than 11 children per elderly person and Europe and Northern America at around 3 children per elderly person (Table 2).

Today the global ratio for the world’s 7.4 billion people has been halved to about three children per elderly person. While Africa’s population continues to have the highest ratio with nearly 12 children per elderly person, the ratios for Asia and Latin America are close to the current world average. In contrast, the population of Europe, which just recently experienced the Historical Reversal, has slightly less than one child per elderly person.

By 2075 the world’s projected population of 10.7 billion is expected to pass through the Historical Reversal with elderly persons becoming increasingly more numerous than children (Figure 1). The only major region that will not experience the Historical Reversal during the 21st century is Africa, which is projected to have 1.5 children per elderly person in 2100 with some countries, such as Niger, Nigeria and Somalia, having more than twice as many children as elderly. At that time, all the other major regions of the world are expected to have about twice as many elderly persons as children.

The two key factors bringing about the Historic Reversal of population age structures are declining fertility rates and rising life expectancies. In every corner of the world, women are bearing fewer children than in the past. Whereas the average global fertility rate in 1965 was five births per woman, today it has fallen to half that level, with 75 countries or close to half the world’s population experiencing rates below the replacement level of about two births per woman.

In addition to rising life expectancies at birth, people are living longer than ever before as mortality rates among the elderly are declining. Over the past five decades the world’s life expectancy at age 65 has increased by nearly five years, with some countries, such as China, Japan, Singapore and South Korea, making gains of seven or more years. As a consequence, since 1950 the proportion aged 80 and older among the world’s elderly increased from one in ten to one in five. In addition, since the start of the 21st century, the number of centenarians, those aged 100 years or older, has tripled compared to a 20 percent increase in world population.

Moreover, while world population is projected to increase by 40 percent by 2065, the number of elderly aged 65 years or older is expected to more than triple. By that year, some countries, such as China, Germany, Greece, Japan, Italy, Poland, Singapore, South Korea and Spain, are expected to have elderly persons account for one-third or more of their population (Figure 2).

Among the world’s children aged 0 to 14 years, boys are a slight majority at 52 percent. However, due to the higher mortality rates of males, women make up majority among the elderly. Women represent 55 percent of persons aged 65 and older and more than 60 percent of the elderly above 80 years old.

While population age structures worldwide are becoming older, developing countries are going through the aging process at a substantially faster pace than took place in developed countries. For example, France took more than a century and the United States close to three-quarters of a century for their elderly populations aged 65 and over to increase from 7 to 14 percent. In contrast, developing countries, such as Brazil, China, Indonesia, Iran and Thailand, are making that aging transformation in a quarter century or less.

The Historic Reversal and population aging certainly constitute a noteworthy demographic achievement. However, this achievement also comes with significant economic, social and political consequences needing societal attention, policy changes and program adjustments. Although gradual, the effects of population aging on a nation are pervasive and considerable, impacting all major spheres of human activity, including consumption, employment, voting, defense, foreign policy, recreation, health care, entertainment, family, immigration and taxation.

In particular, population aging presents a major challenge to government old age pension systems with more elderly beneficiaries and relatively fewer workers contributing to support them. To sustain pension programs for the elderly, countries have a number of options at their disposal.

Governments may choose to increase taxes, redirect government revenue, reduce benefits or privatize old age pension schemes. Understandably, those options are not met with enthusiasm by the general public, especially the elderly.

Other options include raising below replacement fertility levels and increasing the immigration of workers. However, even if fertility rates were to rise, which seem unlikely in the near term, it would take a couple of decades before the additional children could join the work force.

Adding immigrant workers, in contrast, would immediately expand the labor force. But eventually those workers also age, join the elderly population and rely on government pension programs. Over time this would in turn require even more immigrant workers to support the growing numbers of elderly persons.

Perhaps the least objectionable option to sustain pension programs is to raise the official retirement age. Increases in retirement ages are typically gradual and take effect in the distant future. Nevertheless, proposed increases in the statutory age of retirement, especially when linked to rising life expectancies, are frequently met with protests and demonstrations.

Insofar as none of the options to sustain old age pension programs are popular among voters and most elected officials, the needed policy changes are often postponed coupled with nebulous pledges to “save” old age pension systems. While this may be politically expedient and temporarily calm public anxiety, postponements make needed changes and adjustments even more pressing, difficult and costly in the future.

As a result of low birth rates, improved chances of survival and longer life, the Historic Reversal appears certain to happen in most countries during the 21st century. What remains uncertain, and appears somewhat worrisome at this point in time, is whether governments and the general public will respond effectively, responsibly and in a timely manner to the Historic Reversal and the many challenges being brought about by population ageing.

  1. The author is sincere, and his data seems to be soundly based.

    But sorry, I’m not making, or trusting, any projections out to 2075 based solely on current trends. The many many factors of unexpectedness, possible advanced technology, probable and likely climate-change-related extreme weather events, the question of whether human beings are more intelligent than rats — will we seek to escape an environment that we’re poisoning with our own waste products? — all these things will interfere to ensure that 2075 is not just an extrapolation of current trends.

    • I never understand this style of armchair argument.
      The article lays out the best projections thus providing a first initial guess that is valuable for formulating options and plans.
      No one expects this situation to remain static.
      So what if you don’t trust these projections out to 2075, no one expects plans made now to be immutable. The by line wasn’t Moses.

      This position of yours is similar to those who deny climate change by stating something like ‘we cant know everything about climate’ and concluding that therefore we know nothing and so should do nothing.

      Do you really think that the author of the article is unaware of the issues you point out? But until these eventuate the situation as presented by the author is a solid best guess.
      When or if your conjectures arise, the situation would be reappraised.

  2. One way to counteract the aging of a population is through immigration, as immigrants tend to be younger than the average age of the residents in Western countries. But they might not be the most desirable race or religion for many conservatives.

  3. Immigration simply postpones the problem – and not for long either. Barring catastrophes, we are simply going to have to work or way through this. But I am surprised that no mention is made of the transfer from looking after children to looking after the aged, nor consideration to the fact that, as the societies affected are mostly much richer than in the past, they can easily support extended retirement. And pensions often support manual workers, whose life expectancy is not rising.

  4. Yeah, immigration is a band aid but works for politicians and businesses with short-term sight/planning/goals.

    Really need to reform the labour laws too. The western countries have fallen into a mindset need two people to afford all the good things in life (insert personal definition here) and also economic troubles have influenced people to put off having kids. Not enough has been done in most western countries to make it easier to be a working mom or to keep essential costs down. Education costs more than a house for example – I’m talking about college. Daycare alone eats a huge chunk of income, at the other end of the spectrum. Then factor in food, utilities, all that keeps rising fast and jobs are not being created or pay like they used to

  5. Do you remember the movie “Soylent Green”? The Singularity in which AI melds with the flesh could change everything. There is a real possibility the human race is essentially gone at 2075.
    I guess this means reruns of Lawrence Welk will be playing for a while more.
