"The Demographic Conundrum - An Existential Threat"
The photo was taken on Tuesday. While snow can be a nuisance when driving or walking (at my age), it is also beautiful, and when the sun emerged the sky was a delight!

“The Demographic Conundrum – An Existential Threat”
February 27, 2026
“If we are unable to address our fertility crisis, the U.S. will face an
existential economic crisis driven by a steep decline in fertility rates...”

The term “existential” is used with abandon. Many threats, from global warming to offending transgenders, are deemed existential. They are legitimate concerns but pale to the economic consequences that stem from a decline in birthrates, and an aging population with its attendant healthcare costs.
The scale of the threat is larger than most appreciate. The global total fertility rate (TFR)[1] has roughly halved over the past seventy-five years, from five in 1950 to an estimated 2.4 in 2025, according to the International Monetary Fund. In the U.S., the number is expected to be 1.6 for 2025 versus 3.1 in 1950. Europe’s TFR has fallen to 1.43 from 2.7 in 1950. Israel is the only member state of the 38-member OECD (Organization for Economic Co-operation and Development) with a TFR above replacement. Over the next few decades, populations are set to decline in most of the developed world. It is in sub-Saharan Africa and in Middle East nations like Afghanistan, Iraq and Syria where birthrates remain above replacement.
As to the causes behind the decline, there are many but two worth mentioning. One reflects progress – improvements in birth control, particularly the oral contraceptive pill first approved by the FDA in June 1960, which allowed women to enjoy sex without the worry of pregnancy. As well, in January 1973, with the Supreme Court decision in Roe v. Wade, abortion moved out of the shadows and into legal healthcare. The second cause reflects cultural changes, which include everything from women’s desire to find fulfilling careers, to decisions about family size. As well, in 1968 Paul Ehrlich published The Population Bomb. His popular book warned of a 1970s global crisis driven by over-population. He predicted mass starvation. Instead, as we now know, world population growth peaked five years earlier, and annual global deaths from starvation declined from over a million in 1970 to about 40,000 today.
Demographics is a subject I have written on in the past, most recently two years ago. Fewer children and an aging population suggest changes for Social Security and Medicare. In that essay I wrote: “But there is no way to avoid an aging population with ever-higher costs of healthcare for the elderly. Robots and computers do not pay taxes. People do.” According to data from the Mercatus Center, in 1950 there were 16.5 workers for every one person receiving Social Security. Today that ratio is 2.8 to one. In April 1970, Apollo 13 may have had a problem, but today we have a problem, one largely ignored by politicians from both parties. The astronauts on that Apollo flight resolved their problem. Will we solve ours?
A few days ago, in a talk about CCRCs (continuing care retirement communities), we were informed that Connecticut’s population ranks as the 7th oldest in the union, with 19.1% of population over sixty-five. That number, expected to grow by 57% between 2010 and 2040, implies that over 30% of Connecticut’s population will be over 65 in fourteen years. While the numbers suggest increased demand for CCRCs, those numbers scared the hell out of me. Will Social Security recipients equal the numbers of people paying into the system? What do those numbers say about the viability of Social Security and Medicare? Who will support a growing number of senior citizens?
There are no clear answers as to how to halt declining birth rates. Pronatalism does not receive wide-spread support. Greece, Poland, Japan, Russia, Germany, Italy, France and China are among more than fifty countries whose populations are expected to decline in 2026. As populations shrink, the median age rises. In China, for example, the median age is double what it was fifty years ago. In the U.S., while our population is still growing, the median age has risen from 30 in 1950 to 39 today.
Those trends, both here and abroad, are likely to persist for the next several years. People my age are unlikely to be affected by a declining workplace and a surging retiree base. But unless something drastic is done to address Social Security and Medicare our children and grandchildren will face an existential problem. Starting in 2033, Social Security will not be able to make full retirement payments unless Congress intervenes. Tough choices confront us: raise the age of eligibility, increase taxes, or reduce payments. None are attractive alternatives. As former Chairman of the Council of Economic Advisors Herb Stein famously said: “If something cannot go on forever, it will stop.” Increases in legal immigration may provide a short-term solution – one that should be pursued, in my opinion – but with world population growth slowing, it is not a long-term answer.
Nevertheless, a response to these concerns might well emerge from left field. At the risk of sounding Panglossian, I took comfort in a recent op-ed in The Wall Street Journal by columnist Holman Jenkins. He wrote about some of the foolishness associated with “green” politics. He ended: “A paradox of our time is a media with hair on fire about everything, yet democratic societies so complex, weighty and built on the emergent order of millions of people acting on their own information and initiative...tend to right themselves. They find a sensible course...” His words could apply to this population challenge – that we and the West will find our way out of this demographic maze before it becomes an existential crisis. I pray that we do.
