Biopower is a form of political power that operates by managing human life itself: birth rates, death rates, health, reproduction, and the overall wellbeing of populations. The French philosopher Michel Foucault coined the term in the late 1970s to describe how modern governments shifted from ruling through threats of punishment and death to ruling through the careful administration of living bodies. In Foucault’s words, biopower is “what brought life and its mechanisms into the realm of explicit calculations and made knowledge-power an agent of transformation of human life.”
From the Sword to the Census
To understand biopower, it helps to see what came before it. For most of human history, a ruler’s power was fundamentally about death. A king could execute you, send you to war, or let you live. Foucault called this “sovereign power,” and he summarized it as “the right to take life or let live.” It was repressive and intermittent: the state mostly left you alone until it needed to punish or conscript you.
Starting in the seventeenth and eighteenth centuries, European governments began to operate differently. Rather than simply threatening death, they became interested in fostering life. They wanted healthier workers, larger armies, more productive economies. The ancient right to take life or let live was replaced, as Foucault put it, by “a power to foster life or disallow it to the point of death.” This was not a clean, overnight switch. Historians note that the emergence of biopower was a messy process of struggle and contestation within existing systems of rule, with older tools like laws and royal decrees still very much in play even as new techniques took hold.
How Populations Became Visible
The engine that made biopower possible was information. In the eighteenth century, governments began collecting data on the people living within their borders in ways they never had before. New fields like demography, statistics, and public health medicine gave states the ability to see their populations as objects with measurable properties: a birth rate, a mortality rate, an age curve, a life expectancy, a state of health.
Foucault described this new way of seeing clearly: “What does population mean? It does not simply mean a numerous group of humans, but living beings, traversed, commanded, ruled by processes and biological laws. A population has a birth rate, a rate of mortality, a population has an age curve, a generation pyramid, a life-expectancy, a state of health. A population can perish or, on the contrary, grow.” Individual variation disappeared into averages and distributions, creating what one scholar has called a “statistical artefact.” And once you can measure something like life expectancy, you can design policies to change it.
Population counts become biopolitical when they start informing government programs that try to affect the size, composition, or life chances of a group of people. A concrete modern example: concerns about low fertility rates in European countries have prompted EU policymakers to reshape gender equality policies into tools designed to simultaneously increase women’s fertility and their participation in the workforce. The data doesn’t just describe the population. It becomes a reason to intervene in it.
Two Poles of Biopower
Foucault identified two connected strategies through which biopower operates. The first targets individual bodies: disciplining them, optimizing their capacities, making them more useful and productive. Think of standardized schooling, military training, or workplace routines that shape how people use their bodies every day.
The second targets the population as a whole. This is where public health campaigns, census-taking, urban planning, and reproductive policies come in. These interventions don’t focus on any single person. They aim to shift statistical trends across an entire group, nudging birth rates up, pushing mortality rates down, extending average lifespans. Together, these two poles created what Foucault called “an explosion of numerous and diverse techniques for achieving the subjugation of bodies and the control of populations.”
Biopower in Public Health
Public health is one of the clearest arenas where biopower plays out. Foucault himself used the history of epidemic response to illustrate different modes of power. Leprosy colonies represented sovereign power: identify the sick, banish them, draw a hard line between the healthy and the condemned. Plague quarantines represented disciplinary power: lock down a city, monitor every household, enforce strict behavioral rules. But the response to smallpox introduced something new. Instead of simply isolating or punishing, governments began studying the epidemic itself, counting the infected, recording their ages, tracking medical outcomes and death rates. Vaccination emerged as a flagship tool, not through force alone, but through understanding the disease statistically and promoting prevention.
The COVID-19 pandemic offered a vivid real-time illustration of all three modes layered on top of each other. In Zimbabwe, researchers identified how the pandemic response moved through distinct phases. Early on, mandatory quarantine at government-run facilities targeted inbound travelers, treating the virus as an external threat to be physically contained. As surveillance data showed local transmission overtaking imported cases, the response shifted to population-wide norms: mask mandates, physical distancing requirements, bans on gatherings, hand-washing campaigns, and temperature checks. The introduction of COVID-19 testing shifted things further. Proof of a negative test became a requirement for travelers and workers returning to their jobs. Throughout, statistical data was used to justify each change in policy, with epidemiological trends guiding when restrictions tightened or loosened.
Digital Tracking and the Quantified Self
Biopower doesn’t require a government ministry or a public health decree. In the twenty-first century, it increasingly operates through the devices people carry in their pockets and wear on their wrists. Wearable fitness trackers, health apps, and digital platforms like mHealth and eHealth have created new models of healthcare that rely on constant data collection about individual bodies: steps walked, calories consumed, heart rate, sleep patterns.
Scholars describe this as a “biopolitics of the self,” where the body is made manageable through agreed-upon fitness norms. Walking 10,000 steps a day, eating five servings of fruits and vegetables, hitting a target heart rate zone: these are not laws, but they function as standards against which people measure and regulate themselves. At the core of self-tracking culture is a desire for control. You change a behavior, you see the numbers shift, and the feedback loop keeps you disciplining your own body without anyone telling you to.
The larger significance is what happens when all that individual data scales up. Personal health metrics, aggregated across millions of users, become population-level datasets. Researchers describe this as a shift from the “Quantified Self” to the “Quantified Us,” where individual tracking data feeds prediction models, risk analyses, and policy decisions at the macro level. Your fitness tracker isn’t just helping you sleep better. It’s contributing to a data infrastructure that makes populations legible and governable in ways Foucault could only have imagined.
Necropolitics and the Limits of Biopower
Not everyone finds Foucault’s framework sufficient. The Cameroonian philosopher Achille Mbembe introduced the concept of “necropolitics” as a corrective, arguing that biopower cannot fully explain the contemporary politics of death, particularly in colonized and racialized contexts. Where biopower is about managing and optimizing life, necropolitics focuses on how sovereignty is exercised through the power to dictate who must die. Mbembe describes the creation of “death-worlds,” spaces where entire populations are reduced to what he calls “the living dead,” stripped of political status and exposed to conditions designed to destroy them.
The relationship between the two concepts is debated. Some scholars argue that necropower is best understood as the convergence of biological racism and sovereign power, both of which Foucault himself addressed under the terms “state racism” and “thanatopolitics.” On this reading, necropolitics doesn’t describe a genuinely new form of power so much as it sharpens attention on the deadly applications of categories Foucault had already sketched. Others maintain that Mbembe’s framework captures realities, particularly in the Global South, that Foucault’s European-centered analysis left underexplored.
Why the Concept Still Matters
Biopower is useful because it reframes how you think about political control. It shifts the focus away from dramatic acts of repression, armies in the streets, political prisoners, public executions, and toward the quieter, more pervasive ways that power operates through the management of everyday life. Vaccination campaigns, fertility policies, health data platforms, insurance algorithms, pandemic lockdowns: none of these look like traditional domination, but all of them shape who lives, how long, and under what conditions. Understanding biopower means recognizing that the most effective forms of control often don’t feel like control at all. They feel like public health, personal wellness, or just common sense.
