In high-income nations, fertility fell below replacement in the 1970s, and took a leg down during the pandemic. It’s dropping in developing countries, too. India surpassed China as the most populous country last year, yet its fertility is now below replacement.

“The demographic winter is coming,” said Jesús Fernández-Villaverde, an economist specializing in demographics at the University of Pennsylvania. …

Some demographers think the world’s population could start shrinking within four decades—one of the few times it’s happened in history. …

Demographic surprise

In 2017, when the global fertility rate—a snapshot of how many babies a woman is expected to have over her lifetime—was 2.5, the United Nations thought it would slip to 2.4 in the late 2020s. Yet by 2021, the U.N. concluded, it was already down to 2.3—close to what demographers consider the global replacement rate of about 2.2. The replacement rate, which keeps population stable over time, is 2.1 in rich countries, and slightly higher in developing countries, where fewer girls than boys are born and more mothers die during their childbearing years.

While the U.N. has yet to publish estimated fertility rates for 2022 and 2023, Fernández-Villaverde has produced his own estimate by supplementing U.N. projections with actual data for those years covering roughly half the world’s population. He has found that national birth registries are typically reporting births 10% to 20% below what the U.N. projected.

China reported 9 million births last year, 16% less than projected in the U.N.’s central scenario. In the U.S., 3.59 million babies were born last year, 4% less than the U.N. projected. In other countries, the undershoot is even larger: Egypt reported 17% fewer births last year. In 2022, Kenya reported 18% fewer.

Fernández-Villaverde estimates global fertility fell to between 2.1 and 2.2 last year, which he said would be below global replacement for the first time in human history. Dean Spears, a population economist at the University of Texas at Austin, said while the data isn’t good enough to know precisely when or if fertility has fallen below replacement, “we have enough evidence to be quite confident about…the crossing point not being far off.” …

A second demographic transition?

Historians refer to the decline in fertility that began in the 18th century in industrializing countries as the demographic transition. As lifespans lengthened and more children survived to adulthood, the impetus for bearing more children declined. As women became better educated and joined the workforce, they delayed marriage and childbirth, resulting in fewer children.

Now, said Spears, “the big-picture fact is that birthrates are low or are falling in many diverse societies and economies.”

Some demographers see this as part of a “second demographic transition,” a societywide reorientation toward individualism that puts less emphasis on marriage and parenthood, and makes fewer or no children more acceptable. …

In research published in 2021, the University of Maryland’s [Melissa] Kearney and two co-authors looked for possible explanations for the continued drop. They found that state-level differences in parental abortion notification laws, unemployment, Medicaid availability, housing costs, contraceptive usage, religiosity, child-care costs and student debt could explain almost none of the decline. “We suspect that this shift reflects broad societal changes that are hard to measure or quantify,” they conclude.

Kearney said while raising children is no more expensive than before, parents’ preferences and perceived constraints have changed: “If people have a preference for spending time building a career, on leisure, relationships outside the home, that’s more likely to come in conflict with childbearing.” …

‘Plugged into the global culture’

Fertility is below replacement in India even though the country is still poor and many women don’t work—factors that usually sustain fertility.

Urbanization and the internet have given even women in traditional male-dominated villages a glimpse of societies where fewer children and a higher quality of life are the norm. “People are plugged into the global culture,” said Richard Jackson, president of the Global Aging Institute, a nonprofit research and education group. …

Once a low fertility cycle kicks in, it effectively resets a society’s norms and is thus hard to break, said Jackson. “The fewer children you see your colleagues and peers and neighbors having, it changes the whole social climate,” he said. …

New policies

Governments have tried to reverse the fall in fertility with pronatalist policies.

Perhaps no country has been trying longer than Japan. After fertility fell to 1.5 in the early 1990s, the government rolled out a succession of plans that included parental leave and subsidized child care. Fertility kept falling.

In 2005, Kuniko Inoguchi was appointed the country’s first minister responsible for gender equality and birthrate. The main obstacle, she declared, was money: People couldn’t afford to get married or have children. Japan made hospital maternity care free and introduced a stipend paid upon birth of the child.

Japan’s fertility rate climbed from 1.26 in 2005 to 1.45 in 2015. But then it started declining again, and in 2022 was back to 1.26. …

Hungarian Prime Minister Viktor Orban has pushed one of Europe’s most ambitious natality agendas. Last year he expanded tax benefits for mothers so that women under the age of 30 who have a child are exempt from paying personal income tax for life. That’s on top of housing and child-care subsidies as well as generous maternity leaves. …

In the U.S., while state and federal legislators have pushed to expand child-care subsidies and parental leave, they have generally not set a higher birthrate as an explicit goal. Some Republicans, though, are leaning in that direction. Last year, Trump said he backed paying out “baby bonuses” to prop up U.S. births, and GOP Arizona Senate candidate Kari Lake recently endorsed the idea. …

Economic pressure

With no reversal in birthrates in sight, the attendant economic pressures are intensifying. Since the pandemic, labor shortages have become endemic throughout developed countries. That will only worsen in coming years as the postcrisis fall in birthrates yields an ever-shrinking inflow of young workers, placing more strain on healthcare and retirement systems.

Neil Howe, a demographer at Hedgeye Risk Management, has pointed to a recent World Bank report suggesting that worsening demographics could make this a second consecutive “lost decade” for global economic growth.

The usual prescription in advanced countries is more immigration, but that has two problems. As more countries confront stagnant population, immigration between them is a zero-sum game. Historically, host countries have sought skilled migrants who enter through formal, legal channels, but recent inflows have been predominantly unskilled migrants often entering illegally and claiming asylum.

High levels of immigration have also historically aroused political resistance, often over concerns about cultural and demographic change. …

As birthrates fall, more regions and communities experience depopulation, with consequences ranging from closed schools to stagnant property values. …
