The ancient Greeks have exerted tremendous influence on western thought and culture, including in the realm of ethics. Yet few today realize that the founders of western political philosophy advocated a steady-state economy and limits to human numbers. by Theodore P. Lianos In the fifth century B.C., the Athenian philosopher Socrates (470-399) changed the course…
The world population has hit 8 billion, a milestone which has been widely discussed in the media. In this article originally published by The Hill, William Ryerson of the Population Media Center and Kathleen Mogelgaard of the Population Institute reflect on the economic and environmental effects of this milestone. By William Ryerson and Kathleen Mogelgaard…
Sub-Saharan Africa (SSA) is the only world region projected to continue population growth in the second half of this century, and even beyond 2100. In SSA, religion and religiosity are major factors contributing to the persistent high birth rates. A new publication by TOP co-workers is reviewing the relationship between human fertility and religions in…
That’s the title of a paper just published in Biological Conservation in response to TOP’s recent paper on population and biodiversity loss in that journal. Are its authors right? by The Overpopulation Project In one sense, Alice Hughes and company clearly are correct. Efforts to protect wild nature are ongoing throughout the world, and for…
Human population growth has exploded during the last century, decimating wildlife and devastating ecosystems. Without honest conversations about overpopulation, continued growth will likely condemn most wild animals to extinction and leave us with a much poorer planet By Brad Meiklejohn “Fewer people, more wild animals. Right now that feels like coming back from a time…
Excessive and growing human numbers are a leading cause of decreasing biodiversity in many parts of the world. In researching a paper on this topic last year, we became aware of the large amount of good scientific work recently published on it. In an effort to spur more such work, we are publishing an annotated…

In his article originally published at Overpopulation News, Jon Austen explores how the media ignores the benefits of such a decline and finds agreement among commenters. By Jon Austen China has had its first fall in population in 61 years. The media…
Many politicians, the public, and some scientists still think that economic development is a major cause of reduced birth rates in developing countries. We tested this belief empirically in a recently published long-term study of many countries (1970-2014). We found no relationships between fertility and economic growth, but a strong association with modern contraception: birth rates…
At the end of 2022, the Wittgenstein Centre for Demography and Human Capital held a conference titled Population and Climate Change: The Defining Relationship of the 21st Century. Yet as one participant noted, in this presentation from the conference, the desire to downplay population’s importance is hard to avoid, even among those who should know…
According to the United Nations Population Fund, reaching a global human population of 8 billion is an achievement to be celebrated. In “a world of infinite possibilities,” they state, “imagine the boundless paths 8 billion can take.” Rather than taking refuge in irresponsible fantasies, it’s time our bloated societies reckoned honesty with demographic reality.
