About the book

After the Spike envisions, and is written to promote, an abundant future where people collaborate, give, and innovate to make lives better, longer, healthier, safer, and happier than they otherwise would be. It is concerned both with the wellbeing of the global poor today and with the long-term flourishing of humanity.

For decades, many have claimed that fewer people would be better—better for the planet, better for the people who remain. This book challenges the old tropes that still influence the public discourse, and invites a broad audience to consider the possibility that a key challenge for humanity’s future is not too many people on a crowded planet but too few to sustain the progress that has lifted billions out of poverty and reduced social inequality.

In the book, we make the case that depopulation is a global priority area. We do so through ethical arguments and by examining social scientific data. The book is written to be accessible to a broad audience, but is full of details and arguments that are likely to be new to even expert readers who think about long-term wellbeing.

Our publisher says we can’t post excerpts from the book at this time, but below we preview the Table of Contents for the first time, and we include comments from friends and colleagues who reviewed an advance draft.

If you would like to help

What we hope for the book is that many people find it, read it, and discuss it. Making people aware that the book exists is the hardest part. Presales ahead of the publication date will help with that goal in two ways: (1) Exposure via bestseller lists and (2) affecting how many copies are ordered by retailers and printed by the publisher.

Pre-sales count as first-week sales for bestseller lists, so will improve the book’s chances to land on bestseller lists in its publication week. Bestseller lists create awareness of the book among a wider audience who may otherwise never be exposed.

Pre-sales also send a clear market signal to retailers about how many copies they should order and how they should stock their shelves. That signal feeds back to the publisher, affecting how many copies are printed. In this way, early pre-sales can help avoid a situation in which retailers run out of books. The early signal is especially important when publishers aren’t sure whether to expect a book to connect to a wide audience–like the case of a nonfiction book that discusses the long-term future, ethics, population statistics, the history of innovation and economic growth, and the lives of the global poor! If you are likely to read the book at some point anyway, it’s extra helpful if you order it now.

What some friends and colleagues have said about the book:

“After the Spike is a remarkable blend of empirical research and philosophical argument that has challenged, and changed, my thinking about population.  I expect it will do the same for you.” —Peter Singer

“Spears and Geruso take us by the hand to understand the most dramatic period of human history—how a global population of millions became billions—but, importantly, what happens next. The insights and rigour—which come thick and fast—are matched by human and empathetic narrative.” — Hannah Ritchie

“What an eye-opener: Spears and Geruso masterfully weave together demographic data, economic theory, and vital moral insights into a gripping tale of loss to come. They explain where humanity is headed if we don't change course soon, and why it matters so much that we find a better path." —Richard Y. Chappell

“So few books can combine a big-picture vision for humanity’s future with such rigour, insight, and compassion.” —Toby Ord

“This is popular economics at its finest. Dean and Mike meticulously take apart all the myths and confusion surrounding the incoming demographic changes for our species, while making clear the enormous stakes for freedom, equal rights, and human prosperity. Rarely has such an explosive topic been treated with such a combination of urgency and patient explanation. I had my mind blown over and over and over, and you will too.”—Zach Weinersmith

"A fascinating introduction to one of the most important policy questions of our time. This engaging, informative book will make you question what you have heard about population. With depth and nuance, this book shows how parenting can be reclaimed as a progressive cause." –Maya Eden

“Breaking apart from the familiar natalism and anti-natalism debates, Geruso and Spears make a rousing case for population stabilization that is as stirring as it is thoughtful, rigorous and morally uncompromising. Pushing against the alleged self-evidence of the benefits of a declining population—to the environment, to women—After the Spike shows why a stable population is not just compatible with climate action, gender equality and a higher, equitably-distributed standard of living, but why it may just be their necessary condition.” –Anastasia Berg

“After the Spike is an important book. Demography is destiny; Spears and Geruso tell a surprising story and show us how to shape that destiny for a sustainable, flourishing world.“ 
—Anne-Marie Slaughter
