Global Aging Adds New Wrinkle to Population Problem

There are more old people alive today than ever before, putting new strains on social security and raising questions about the value of longevity itself.

Start Date: 2/25/99

The cover story of the March 1, 1999 edition of the respected weekly magazine U.S. News and World Report is titled "The Global Aging Crisis." The story reveals that in the year 2000, for the first time ever, the developed countries of the world will have more people aged 60 and up than youths aged 14 and under. For the world as a whole, the same will be true by the year 2043.

The implications of a human population that is both growing and aging are numerous and worrying. In traditional societies the world over, as well as in modern societies served by social security systems, a fundamental assumption has been that young people will substantially outnumber the elderly and will provide, directly or indirectly, for the welfare of those who are past their productive working years. However, in a world where the elderly are becoming more numerous than the young, the bedrock assumptions of social security are in serious trouble.

The shift in age distribution is driven by two major forces. First, birthrates are declining in most parts of the world, but especially in the industrialized nations. And second, life expectancy is increasing almost everywhere.

Paradoxically, although total global population is expected to climb dramatically to more than 9 million people in the year 2050, population will actually decrease in many major nations during that period. Among those with negative population growth will be Russia, Japan, and most of the nations of Central and Western Europe. Population growth will also slow almost to replacement level (2.1 children per family, or "zero population growth") in the United States and Canada, Australia and New Zealand, France, Thailand, North and South Korea, and China. In all of these countries, by the year 2050, the number of people over the age of 60 will likely outnumber those aged 14 or less by a margin of two to one.

The question is, how will human society adjust to a population that is nearly one-third senior citizens? How will social security systems manage the transition? And how will seniors themselves rethink their options and deal with their vulnerabilities in a world that no longer offers a "golden parachute"?

In terms of conventional wisdom, the most-often heard suggestion is that employed people will be forced to pay ever-higher taxes to support the growing ranks of retirees. Past a certain point -- a point not many years away -- that option reduces to absurdity. The real long-term answers are harder to contemplate, but must be faced. These include raising the average retirement age, changing and diversifying the nature of social security funding, and focusing on maximizing the quality of life for the elderly, rather than simply increasing longevity.

Advances in medical science, nutrition and fitness, and even bio-engineering point to the day when many human beings will have the option of living well past the age of 100. But will that longevity greatly aggravate the young-old divide without substantially elevating the quality of senior life? If so, individuals and society as a whole will have to ponder whether longevity itself is a worthy goal. The answers will not be easy to come by.




Excelsior, Michael Lindemann's new novel (written under the pen name Michael Paul), depicts a wholly plausible near future in which human cloning is both widespread and widely abused; terrorists have access to target-specific biological weapons; recreational space travel is commonplace; and mounting pressures of global climate change, environmental decline, population growth and civil unrest inspire radical new approaches to urban security.
