Preface

I am not a demographer. I trained as a mechanical engineer, then in quantitative communication studies, with detours through political science and business. I now work as a computational social scientist in the discipline of misfit toys known as information science. Statistical modeling and data science methods remain central to my professional identity. I am most at home when studying the digital traces of social behavior from online communities like Wikipedia, Reddit, or Twitter. Readers looking for a jeremiad about the limits of numbers or settling internecine debates between “quantitative” and “qualitative” epistemologies will be disappointed.

What this book does do is to reclaim quantitative methods from reactionary political projects that have, for decades, abused data to advance unjust and cruel visions for the world. Collecting, analyzing, and interpreting numerical data has never been neutral and this tradition has much to answer for. Quantitative data and methods will play a crucial role in the contemporary polycrisis of metastasizing democratic backsliding, accelerating climate crisis, and compounding technological disruptions. A more reflexive post-positivism that grapples with the social construction and political economies of data will not rescue us from this polycrisis, but it could help clarify the consequences of data analysis choices and to inoculate ourselves from uncritical appeals to numbers.

There is one key bit I omitted from my biography: my exposure to science and technology studies (STS) as an undergraduate student transformed my educational and professional trajectories. STS as a discipline has a geneaology that coalesced alongside the Cold War history of demography that later chapters trace. STS scholars study how the construction, circulation, and consequences of scientific methods and technological tools within and between social groups. This project is therefore a homecoming to my STS roots after almost two decades in the theories and methods of other disciplines. As a STS project, it combines historical, rhetorical

I do not claim the authority of the professional demographer who can evaluate Bartlett’s models from inside the discipline he was inverting. What I can evaluate is the rhetorical and organizational structure of how those models traveled: from the lecture hall to the policy document, from the physics classroom to the advisory board of an immigration-restriction organization, from the pedagogy of exponential arithmetic to the production of moral permission for coercive governance.

Three additional motivations converge in this project. The first is professional. Since 2018, access to the social data that quantitative researchers rely on for scholarship, journalism, and civic accountability has retreated behind rationales of privacy, monetization, and artificial intelligence training. This retreat is not neutral: it selectively forecloses the kinds of empirical inquiry that might contest quantitative claims made by institutions with privileged data access. The second motivation is political. The post-2016 national landscape has made legible a pattern that was already present in the archival record: demographic projections, environmental scarcity arguments, and immigration restriction claims recycled across generations within a durable organizational infrastructure. The third motivation is the one the archive supplied: the recognition that the infrastructure consecrating Bartlett’s authority continues to confer legitimacy on the arguments he developed with it, long after his death and long after demographic science has moved on.

The word that names what this book analyzes is ecofascism, and this book uses it deliberately and early, before establishing the analytical scaffolding that will eventually support it with more precision. The choice is deliberate because the concept has a history of appearing belatedly in scholarship that circles the phenomenon without naming it, treating it as a fringe inflection of mainstream environmentalism or a rhetorical excess to be distinguished, carefully, from the legitimate environmental concern it resembles. This book declines that evasion. The fusion of ecological emergency with racialized demographic hierarchy, the mobilization of environmental scarcity arguments to justify coercive governance of populations defined by race and national origin, the inscription of exclusionary political projects in the language of natural limits and arithmetic necessity: these are not deviations from respectable environmentalism that require only careful taxonomic separation. They are a coherent and historically durable political formation that requires a name, a mechanism, and a genealogy.

The name is not a verdict on individuals. Calling someone an ecofascist is a prosecutorial act that this book does not perform. What the book does instead is trace ecofascist imaginaries: the ensemble of future narratives, organizational practices, and rhetorical repertoires through which ecological emergency is converted into demographic hierarchy and coercive governance is presented as reluctant but responsible management of natural limits. Bartlett’s archive does not establish that he held ecofascist beliefs. It establishes that his institutional authority was recruited by and lent to organizations that operated through ecofascist imaginaries, and that he did not resist that recruitment. The distinction matters analytically. An imaginary is not an individual’s conviction: it is a collective structure that makes certain actions seem necessary, certain populations seem threatening, and certain policies seem like responsible concessions to reality. Individuals enter and exit these structures; the structures persist.

The other name this book requires is quantitative chauvinism: a style of reasoning that elevates a privileged metric into jurisdiction over political judgment, collapses heterogeneous social complexity into a single aggregated trajectory, and then inscribes the result in portable artifacts that travel as if they were neutral facts. Quantitative chauvinism is not numeracy’s shadow. It is something more specific: the use of quantitative form to close political questions before they can be opened, to present simplifications as comprehensiveness, and to frame dissent as a failure to understand the data. Bartlett’s lecture was its clearest pedagogical expression: a small set of graphs, a doubling-time calculation, and a rhetorical performance that transformed arithmetic demonstration into moral mandate. The lecture’s portability—more than 1,700 performances across four decades—was not incidental but structural. The form taught the content. Students who left the lecture knowing how to calculate a doubling time also left knowing how to treat that calculation as a sufficient basis for urgent policy demands.

The two concepts are analytically inseparable, and their interaction is the book’s central argument. Quantitative chauvinism provides the epistemic infrastructure that ecofascist imaginaries require: without simplified models that suppress feedback and alternative trajectories, naturalizing demographic hierarchy loses its causal warrant; without expertise that confers authority on simplification, hierarchizing populations loses its scientific alibi; without the foreclosure of alternatives that quantitative inevitability performs, instrumentalizing coercive governance loses its claim to reluctant necessity. The chapters that follow trace this interaction across four historical eras and one projected future. The goal is not to discredit quantification but to show what happens when quantitative form is separated from the epistemic commitments—uncertainty, validation, democratic contestation—that give it legitimate authority.

This book addresses four scholarly communities whose debates converge on the problem it analyzes. For scholars in science and technology studies, the manuscript contributes a case study in how quantitative authority is constructed, made portable, and recruited for political ends—a story that extends Porter’s account of mechanical objectivity as a technology of trust into the specific domain of demographic pedagogy and its organizational afterlives. For scholars in critical and historical demography, it contributes a genealogy of the population concern community’s institutional entanglement with exclusionary politics, tracing how the post-World War II convergence of demographic science and environmental advocacy produced the rhetorical and organizational infrastructure that would later channel those arguments toward immigration restriction and replacement anxiety. For scholars in environmental sociology and political ecology, it contributes an account of how the greening of nativist politics operates through quantitative form: how scarcity arguments, carrying-capacity frameworks, and environmental impact metrics become portability engines for racial and national hierarchy. And for scholars in extremism studies and the sociology of far-right movements, it contributes a mechanism for understanding how mainstream scientific and institutional authority is recruited by extremist organizational networks without those networks having to capture the institutions outright—how a physicist’s lecture becomes usable by a hate group without the physicist ever joining one.

The urgency of addressing these four communities simultaneously is the book’s methodological premise. The ecofascist imaginaries this book analyzes are not legible from inside any single disciplinary framework. They require the tools of STS to trace how quantitative authority is built and made portable; the tools of critical demography to situate those authority claims within the history of population knowledge as governance knowledge; the tools of environmental sociology to explain how ecological emergency becomes a warrant for demographic hierarchy; and the tools of extremism studies to analyze the organizational forms through which those warrants travel from scientific institutions to political movements. No single framework is sufficient, and the chapters that follow move across these fields deliberately, treating their intersection as the analytical territory the book maps.

A final motivation is inoculation—a term I use in a limited, pragmatic sense. Inoculation names a practice of anticipatory recognition: learning the recurring rhetorical and technical moves by which numerical claims are converted into moral permission structures, then rehearsing how to identify and interrupt those moves before panic hardens into policy. Quantitative chauvinism rarely announces itself as domination. It presents itself as responsibility: a small set of numbers, a graph, a trajectory too steep to ignore. Ecofascist imaginaries intensify the effect by binding those projections to narratives of ecological emergency, scarcity, invasion, and triage. The chapters return to this coupling repeatedly—across eras, instruments, and organizational formations—so that its signature becomes recognizable.

A Politically Direct Closing

The organizations this book analyzes are not historical curiosities. The Federation for American Immigration Reform, the Center for Immigration Studies, NumbersUSA, and the network of affiliated outlets and advocacy organizations that John Tanton assembled from the late 1970s onward remain active, well-funded, and institutionally connected to federal immigration enforcement policy. The arguments they deploy—demographic projections, environmental carrying-capacity frameworks, fiscal impact assessments—continue to circulate through media environments that treat numerical form as evidence of seriousness. Under the second Trump administration, those arguments have moved from the advocacy fringe into direct governance: immigration enforcement has expanded dramatically, public demographic data has come under selective pressure, and the language of environmental and demographic emergency has been applied to populations that established immigration law defines as eligible for protection. The Tanton network did not create these conditions, but it built the infrastructure—the policy papers, the think-tank credibility, the congressional testimony, the lexicon of environmental necessity—through which they could be rationalized and institutionalized.

This book is not a neutral account of these developments. It is a diagnostic project with a political stake in its own conclusions. The distinction this book makes—between the legitimate practice of quantitative inquiry and the organized project of converting quantitative claims into coercive governance—is itself a political act, and the book makes no apology for it. What I refuse is the choice that quantitative chauvinism always tries to impose: between accepting its simplified projections as mandates and being dismissed as innumerate. That is a false choice, and naming it as such is the book’s first task.

The book’s constructive proposal is quantitative egalitarianism, grounded in three commitments. First: treat models as conditional representations, not moral verdicts. Require explicit assumptions, uncertainty quantification, and validation. Make visible what the model suppresses. Second: treat data as civic infrastructure. Protect access, provenance, and accountability through governance that serves democratic publics rather than private enclosure or institutional self-interest. Third: treat measurement as an arena of democratic contestation. Make categories, metrics, and trade-offs available for challenge, especially when they govern mobility, belonging, and differential exposure to harm. These commitments do not produce a blueprint for a better demographic model. They produce a set of institutional demands: that the assumptions behind every projection be available for scrutiny, that the populations governed by those projections have standing to contest them, and that the numerical claims made in the name of environmental necessity be answerable to the pluralistic democratic life they claim to protect.

This book opens and closes in Boulder, Colorado. Boulder is useful not because it is exceptional but because its trajectory is legible: a nominally progressive community where the slide from conservation into exclusion has been accomplished gradually enough that each step looked, from the inside, like responsible stewardship. Its hazards expose the limits of control. Its planning culture exposes the temptations of quantitative chauvinism. Its environmental self-image exposes how easily conservation slides into coercion when the categories used to define the community worth conserving are treated as natural rather than political. Yet Boulder’s institutional history also contains the resources for a different kind of quantitative governance: one that treats the city’s environmental future as a question that belongs to everyone who lives within its projected boundaries, not only to those who already own a place in it.

The measure of a livable future will not be the precision of our forecasts. It will be the equity of our arrangements for bearing risk, sharing space, stewarding ecosystems, and contesting the numbers that shape whose lives those arrangements protect. That measure is harder to calculate and harder to inscribe in a portable artifact, which is exactly the point.
