“It is not in the stars to hold our destiny but in ourselves.” – William Shakespeare
Can you imagine a world in which population growth is flat? How about negative?
Fifty years ago such questions would have been dismissed as absurd. At the time, global population growth was increasing at a rate of 2.1% per year. Today, with that growth rate down to 1.1%, the concept seems less ridiculous but still hard to fathom.

If projections are correct, however, by 2050 population growth will move all the way down to 0.6%.
In 2050, there will likely be many, many countries with negative population growth rates. How can we forecast such a thing?
Because it is already happening. In 77 countries, the fertility rate (average number of children born to a woman over her lifetime) has fallen below 2.0, the level necessary to sustain population levels.
Of the 25 most populous nations, Japan, Germany, and Russia already have shrinking populations. Italy and France would by negative as well but not for immigration.
Where is the growth coming from? The emerging world in Africa, Latin America, Asia, and the Middle East. Europe is not far from shrinking as a continent and without immigration would already be there.
The economic, political, and social ramifications of a rapidly shrinking global population are many. Too many to delve into in just one post.
But as economic output (GDP) is dependent in part on population growth, we should probably be expecting lower growth rates in the years to come. We are already seeing this in the U.S. and globally.
Unless productivity shows a significant increase, output will slow. Does that mean that the world is going to end? No, I don’t believe so but it will mean that expectations will have to be reset lower. The hopes and dreams of getting back to 4% GDP growth may not be achievable for the time being. That would be acceptable, though, as long as the standard of living continued to increase.
The problem is that the last 20 years in the U.S. has seen slower growth and a declining standard of living (as measured by median real household income). That’s a toxic combination with no simple solutions. It is also the proximate cause for much of the dissatisfaction we have in the U.S. in spite of all-time highs in stock prices and seven years of economic expansion.
In Europe and Japan, one “solution” to slower growth has been negative interest rates. You’ll notice in the table below that every country with a negative interest rate has a fertility rate below replacement levels. This is hardly a coincidence.
Will negative interest rates solve their growth problems? Not unless it can magically lead to higher fertility or productivity. There is scant evidence of that happening and some speculation that it may have the opposite effect. I say speculation because we are in uncharted territory here. No one truly knows.
For thousands and thousands of years, population growth advanced at a snail’s pace (roughly 0.1% per year). The industrial and scientific revolutions changed that with a bang. Global population first hit 1 billion in 1804 and today stands at over 7 billion.

That increase is over 9x as fast as the previous 6000 years.
When viewed in that context, perhaps a decline in growth was inevitable and not entirely a bad thing. Perhaps there needs to be a period of digestion where humans can figure out how to best utilize the existing resources of this planet or invent new technologies. Perhaps a growth rate of over 2% as we saw in 1966 was unsustainable and will be viewed a thousand years from now as a historical outlier.
I don’t know the answer and I’m not sure there is one. When it comes to demographics, we are left with more questions than answers.
