This blog has published many posts about the U.S. currently experiencing a declining and aging population and seeing one solution in encouraging immigration from other countries that have increasing and younger populations.[1]
This perspective is complicated by some population experts seeing a future peak in world population and a subsequent shrinkage in same without reaching a plateau and stable population.[2]
Dean Spears’ Opinion
Dean Spears (an economist at the Population Research Center at the University of Texas, Austin) asserts that various experts agree that world population soon will peak and then shrink. Here are those experts’ opinions on the timing of such a peak: U.N. demographers, 2080s; Wittgenstein Center for Demography and Global Human Capital, 2070s; Institute for Health Metrics and Evaluation at the University of Washington, 2060s.
The common element in these projections is families having smaller family sizes. The main reason, Spears claims, is “people want smaller families than people did in the past. Humanity is building a better, freer world with more opportunities for everyone, especially for women. That progress deserves everyone’s continued efforts. That progress also means that, for many of us, the desire to build a family can clash with other important goals, including having a career, pursuing projects and maintaining relationships.”
These competing interests could lead to “backsliding on reproductive freedom—by limiting abortion rights, for example. But Spears says, “low birthrates are no reason to reverse progress toward a more free, diverse and equal world.”
Spears concludes this analysis with the following statement: “Humanity needs a compassionate, factual and fair conversation about how to respond to depopulation and how to share the burdens of creating each future generation. The way to have that conversation is to start paying attention now.” (Emphasis added.)
Wall Street Journal’s Perspective
The Wall Street Journal begins its article, “The world is at a startling demographic milestone. Sometime soon, the global fertility rate will drop below the point needed to keep population constant. It may have already happened. Fertility is falling almost everywhere, for women across all levels of income, education and labor-force participation. The falling birthrates come with huge implications for the way people live, how economies grow and the standings of the world’s superpowers.” (Emphasis added.)
“Many government leaders see this as a matter of national urgency. They worry about shrinking workforces, slowing economic growth and underfunded pensions; and the vitality of a society with ever-fewer children. Smaller populations come with diminished global clout, raising questions in the U.S., China and Russia about their long-term standings as superpowers.” (Emphasis added.)
“Some demographers see this as part of a ‘second demographic transition,’ a society wide reorientation toward individualism that puts less emphasis on marriage and parenthood, and makes fewer or no children more acceptable.”
According to Professor Melissa Kearney of the University of Maryland, “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. . . . 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. Meanwhile, time-use data show that mothers and fathers, especially those that are highly educated, spend more time with their children than in the past. The intensity of parenting is a constraint.”
“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 past crisis fall in birthrates yields an ever-shrinking inflow of young workers, placing more strain on healthcare and retirement systems.” (Emphasis added.)
Conclusion
These articles were the first that this blogger had heard of a projected decline in world population which if and when it happened would have a major impact on many countries and national and international economics and politics. Comments by others on this topic are encouraged.
