Early Twentieth-century France confronted an existential menace: Its residents weren’t having sufficient infants. In 1900, the common French lady gave beginning to a few youngsters all through her lifetime whereas over the border in Germany ladies had been averaging 5. For many years, France’s inhabitants had hovered stubbornly at round 40 million whereas that of its European rivals grew bigger. “It’s the most vital truth in French life. In no different nation on this planet is the beginning fee so low,” wrote American journalist Walter Weyl in 1912.

French society swung into motion to avert the disaster. Pronatalist organizations sprung up, and by 1916 half of all French parliamentarians had been a part of a lobbying group that pushed insurance policies aimed toward elevating beginning charges. An annual prize was inaugurated, awarding 25,000 francs to 90 French dad and mom who had raised 9 or extra youngsters. Legal guidelines limiting abortion and contraceptives had been handed, and moms of enormous households had been honored with medals based on what number of youngsters that they had raised.

None of this shifted the trajectory of France’s falling beginning charges. “Forty-one million Frenchmen face 67 million Germans and 43 million Italians,” lamented former minister Paul Reynaud in January 1937. “So far as numbers are involved, we’re overwhelmed.” Reynaud was proper, in fact, however just for so lengthy. Within the many years after World Warfare II, the French inhabitants swelled—bolstered by a child growth and powerful immigration. This postwar growth has lengthy since worn off, however France nonetheless has the very best fertility fee of any EU nation: The much-feared inhabitants collapse by no means got here to cross.

Nervousness about falling populations, nevertheless, by no means went away. Now essentially the most distinguished public worrier is Elon Musk, for whom stagnating beginning charges don’t simply symbolize a disaster for particular international locations, however an existential menace to the complete planet. “Assuming there’s a benevolent future with AI, I believe the most important downside the world will face in 20 years is inhabitants collapse,” Musk stated at an AI convention in August 2019. The problem is clearly enjoying on his thoughts. “Inhabitants collapse attributable to low beginning charges is a a lot larger danger to civilization than international warming,” he tweeted in 2022. “Mark these phrases.”

Demographers have marked Musk’s phrases—however they don’t agree together with his dire predictions. “With 8 billion individuals and relying on the earth, we don’t see a collapse taking place at current time, and it’s not even projected,” says Tomas Sobotka on the Vienna Institute of Demography. Even essentially the most pessimistic projections put the world inhabitants in 2100 at round 8.8 billion. That is far under the UN’s extra broadly agreed upon estimate of 10.4 billion, nevertheless it’s nonetheless about 800 million extra individuals than are on the planet as we speak. Most projections agree that the world’s inhabitants goes to peak in some unspecified time in the future within the second half of the twenty first century after which plateau or regularly drop. Framing this as a collapse “might be too dramatic,” says Patrick Gerland, chief of the United Nations’ Inhabitants Estimates and Projections Part.

In accordance with the UN, the one area that may see an total decline between 2022 and 2050 is japanese and southeastern Asia. Different areas inform a very completely different story. The inhabitants in sub-Saharan Africa will virtually double from 1.2 billion in 2022 to simply underneath 2.1 billion in 2050. In the identical interval, India’s inhabitants will develop by over 250 million to overhaul China’s as the biggest on this planet. For many of the world, inhabitants decline simply isn’t one thing to fret about—“both now or within the foreseeable future,” Gerland says.

However what in regards to the very distant future? Japan’s inhabitants is already declining, and the nation has one of many lowest whole fertility charges on this planet—Japanese ladies common 1.3 youngsters throughout their lifetime. For a inhabitants to remain fixed, this quantity would have to be 2.1, assuming there’s no migration and that life expectancy stays roughly fixed. If the fertility fee stays under 2.1 for lengthy sufficient, the inhabitants quantity will begin to fall. In Japan, we are able to see this taking place—having peaked at 128.1 million in 2010, the nation’s inhabitants slowly fell to 125.8 million over the next decade.
