Biopower vs Biopolitics in Foucault: What's the Difference?

The short answer

Biopower is Foucault’s term for modern forms of power that take human life itself—both individual bodies and populations—as an object to be managed, regulated, and optimized. In The History of Sexuality, Vol. 1 (1976), Foucault contrasts this with the older sovereign power expressed through the right to “take life or let live.” From the seventeenth century onward, he describes the emergence of a form of power increasingly concerned with fostering life, administering health, regulating bodies, and managing the conditions in which populations live. He describes biopower as having two interconnected poles: an anatomo-politics of the human body, which disciplines and trains individual bodies, and a biopolitics of the population, which regulates collective processes such as birth rates, mortality, health, longevity, and living conditions.

Biopolitics therefore refers specifically to the population-oriented pole of this broader power over life. However, Foucault’s terminology is not always used as a rigid technical distinction, and later scholars sometimes use biopolitics and biopower in different or overlapping ways. The central point is that modern power does not operate only by threatening or taking life; it also works through institutions, knowledge, public-health measures, statistical practices, norms, and forms of administration that seek to organize and regulate living individuals and populations. For broader context, see our main Foucault guide.

Two poles of biopower

The first pole is covered in our Discipline and Punish summary.

From sovereign power to biopower

Foucault describes the emergence of biopower as a shift from sovereign power, centered on the right to “make die and let live,” toward modern forms of power concerned with “make live and let die.” In his account in The History of Sexuality, Vol. 1 (1976), the distinction does not mean that sovereign power simply disappeared or that modern states stopped using coercion or violence; rather, it identifies a change in the dominant way power increasingly operates. Sovereign power was traditionally expressed through the authority of a ruler over subjects, including the power to punish, take life, or permit life to continue, whereas modern power increasingly takes the biological and social processes of life as objects of administration. From the seventeenth century onward, Foucault identifies two interconnected developments: disciplinary power directed toward individual bodies, and regulatory mechanisms directed toward populations. Individual bodies could be trained, examined, classified, and made more useful through institutions such as schools, barracks, hospitals, workshops, and prisons, while populations could be studied and regulated through knowledge and practices concerning birthrates, mortality, disease, health, life expectancy, reproduction, housing, and other conditions of collective life. In this sense, the population becomes something that can be observed through statistics, measured through demographic and medical knowledge, and acted upon through administrative and regulatory interventions. The state and other institutions therefore increasingly exercise power not only by prohibiting or punishing but also by attempting to foster, regulate, optimize, and normalize life. At the same time, “let die” points to the unequal distribution of protection and exposure to risk within populations: a system oriented toward fostering the life of a population can also determine which groups receive greater protection, resources, or intervention and which may be left more exposed to illness, poverty, or death. Foucault’s point is therefore not that modern power is simply more benevolent than sovereign power, but that its mechanisms and objects have changed: power increasingly works through the administration and regulation of living bodies and populations, while sovereign forms of authority and coercion continue to exist alongside these newer mechanisms.

Where Foucault develops the terms

• The History of Sexuality, Vol. 1 (1976): Foucault gives his most widely cited formulation of biopower in the final chapter, “Right of Death and Power over Life.” He contrasts the sovereign right to “make die and let live” with a modern power concerned with “make live and let die,” and explains how power increasingly takes the biological processes of individual bodies and populations as objects of regulation. He identifies two connected poles: an anatomo-politics of the human body, concerned with disciplining and training individual bodies, and a biopolitics of the population, concerned with collective processes such as births, mortality, health, reproduction, life expectancy, and living conditions.
• Society Must Be Defended (1975–76 lectures): These lectures, delivered at the Collège de France, develop Foucault’s account of biopolitics as a technology of power directed toward populations and connect it to the emergence of modern state practices. Foucault discusses how political power comes to operate on populations through regulatory mechanisms concerned with biological processes such as health, birthrates, mortality, and reproduction. He also examines state racism, arguing that racism can function within biopolitical forms of power by dividing a population into groups and presenting the biological or political survival of one group in relation to the exposure or death of another. This provides an important bridge between his analysis of biopolitics and his later discussion of racism and the state.
• Security, Territory, Population (1977–78 lectures): Foucault shifts attention toward governmentality and the mechanisms through which governments seek to manage populations rather than simply impose laws upon individual subjects. His discussion of security examines practices that work with probabilities, circulation, risks, epidemics, urban conditions, food supply, and other processes affecting populations. Rather than attempting to eliminate every undesirable event through direct prohibition, security mechanisms seek to regulate the conditions and probabilities within which events occur. The lectures therefore help explain how biopolitical power operates through administrative knowledge, statistics, expertise, and techniques of governing.
• The Birth of Biopolitics (1978–79 lectures): Despite its title, this course is not primarily a systematic definition of biopower or biopolitics. Instead, Foucault develops his analysis of liberalism and neoliberalism as forms of political rationality and examines how governments are shaped by particular ideas about the proper limits and functions of government. He discusses German ordoliberalism and American neoliberalism, including the ways economic principles become connected to the practice of governing. The course is nevertheless important for understanding the broader development of Foucault’s analysis of governmentality, showing how his investigation moves from disciplinary and biopolitical mechanisms toward the rationalities through which modern subjects, markets, and populations are governed.
• Related Collège de France lectures: Foucault’s treatment of these ideas is not confined to the four works above. His lectures at the Collège de France form a broader development of his changing vocabulary of power, discipline, governmentality, security, population, and biopolitics. In particular, the transition from Society Must Be Defended to Security, Territory, Population shows how his analysis develops from the relationship between sovereign, disciplinary, and regulatory power toward the study of governmentality and the techniques used to govern populations. These texts should therefore be read as parts of an evolving argument rather than as isolated books in which Foucault gives one fixed definition of biopower.

Examples

• Censuses and demographic statistics: Governments can collect and analyze information about population size, age, fertility, mortality, migration, life expectancy, and other demographic patterns. For Foucault, such statistical knowledge is important because the population becomes an object that can be measured, compared, monitored, and acted upon through policies designed to influence collective conditions rather than simply command individual subjects.
• Public health, sanitation, and vaccination: Measures aimed at controlling disease and improving population health illustrate how political and administrative institutions can intervene in biological processes affecting large groups. Sanitation systems, disease surveillance, vaccination programs, health regulations, and campaigns promoting particular health practices can involve forms of knowledge and regulation directed toward reducing mortality and managing risks across a population. Their inclusion in a Foucauldian analysis does not mean that such measures are inherently oppressive; the concept concerns how life, health, risk, and populations become objects of organized intervention.
• Family planning, reproduction, and birth-rate policies: Reproduction provides another important example because fertility and birthrates can become matters of demographic and governmental concern. Family-planning programs, incentives or restrictions concerning reproduction, and policies designed to influence population growth can therefore be studied in relation to biopolitics. The history of eugenics provides an especially coercive example of attempts to manage reproduction according to supposedly biological criteria, including policies involving compulsory sterilization and selective reproduction in some historical states.
• Health insurance, actuarial practices, and risk management: Insurance and related administrative systems can classify individuals and populations according to risks such as illness, disability, mortality, or life expectancy. Statistical and actuarial techniques make it possible to calculate probabilities and organize resources around those risks. In a Foucauldian analysis, this illustrates how modern governance can operate through measurement, probability, expertise, and management of conditions rather than relying solely on direct commands or punishment.
• Schools, workplaces, and other institutions: Biopower should not be reduced to public-health policy alone. Foucault’s broader analysis connects the regulation of populations with disciplinary practices directed at individual bodies. Schools, military institutions, factories, hospitals, and prisons can classify, observe, examine, train, and normalize individuals while also contributing to wider systems of administration and knowledge. This is why biopower is best understood as part of a broader network of modern power rather than as a single government policy or institution.

The concept has also been applied by later scholars to contemporary controversies, including responses to epidemics and pandemics. During debates over pandemic restrictions, surveillance, vaccination, emergency powers, and the regulation of movement, biopolitical language was used to analyze how states sought to manage collective health and biological risk. Philosopher Giorgio Agamben, for example, invoked related concepts in criticizing aspects of emergency measures during the COVID-19 pandemic, while other scholars disputed his interpretation and argued that protecting public health and restricting certain activities during an epidemic cannot by itself establish the broader Foucauldian claim about biopolitical domination. These later applications are therefore best treated as interpretations and extensions of Foucault’s framework rather than as examples of policies that Foucault himself discussed.

How later thinkers use the terms

Later thinkers use biopolitics and biopower to develop different interpretations of Foucault’s analysis of how political power becomes concerned with human life, bodies, and populations. These later approaches should not be treated as interchangeable with Foucault’s own terminology, because each author extends the concepts toward different philosophical and political questions. Giorgio Agamben connects biopolitics with the distinction between political life and bare life—life reduced to its biological existence—and argues that the camp provides a particularly important model for understanding modern political power and the production of spaces in which ordinary legal protections can be suspended. His approach therefore places greater emphasis than Foucault’s original account on sovereignty, law, the state of exception, and the relationship between political authority and exposed forms of life. Roberto Esposito, meanwhile, develops biopolitical theory through the concept of immunity. He examines how political communities seek protection from threats and how mechanisms intended to preserve collective life can simultaneously produce forms of exclusion or danger. His immunity/community framework gives biopolitics a distinctive vocabulary for examining the relationship between protection, community, and the management of life.

Michael Hardt and Antonio Negri extend the discussion of biopower into an analysis of contemporary capitalism, especially in Empire (2000) and Multitude (2004). They use biopower to describe forms of power that operate not only through institutions and states but also through social production, communication, networks, economic relations, and the production of social life itself. Their interpretation is consequently connected to their broader account of global capitalism and Empire, rather than being a simple restatement of Foucault. Thomas Lemke provides an influential overview of these different developments and emphasizes the need to distinguish Foucault’s historically specific analysis from the many later uses of biopolitics and biopower. Taken together, these interpretations show that the terms have become a broad field of debate: Agamben emphasizes bare life, sovereignty, and the state of exception; Esposito examines community and immunity; Hardt and Negri connect biopower to global capitalism and social production; and Lemke helps clarify the conceptual differences among these approaches.

Frequently asked questions

What is biopower?

A form of power that manages and fosters human life, working both on individual bodies and on whole populations.

What is biopolitics?

The population-level side of biopower: politics concerned with birth, death, health, and longevity.

Are biopower and biopolitics the same?

Foucault often uses them close together. Many scholars treat biopolitics as one pole of biopower, but usage varies.

In which Foucault text does biopower first appear?

In the final chapter of The History of Sexuality, Vol. 1 (1976), and in his 1975–76 lectures.

How does biopower work?

Biopower works by producing knowledge about bodies and populations and using that knowledge to regulate, organize, and manage aspects of life. It can operate through institutions, statistics, medical expertise, public-health practices, demographic policies, surveillance, norms, and other techniques that influence how individuals and populations are governed. Rather than relying only on direct commands or punishment, biopower often works through the regulation of conditions, risks, behaviors, and collective processes.

What are some examples of biopower?

Examples commonly examined through the concept of biopower include censuses, demographic statistics, public-health programs, disease surveillance, reproductive policies, health administration, and systems for managing population-level risks. These practices become relevant to Foucault’s analysis when human life, health, reproduction, mortality, or population processes become objects of systematic knowledge and intervention.

What is the relationship between discipline and biopower?

Disciplinary power focuses primarily on training and regulating individual bodies, while biopower also operates at the level of populations. Foucault presents these as interconnected mechanisms rather than completely separate systems. Discipline can make individual bodies more useful, efficient, and governable, while regulatory mechanisms address collective processes such as birthrates, mortality, health, and longevity. Together, they form important parts of Foucault’s account of modern power over life.

Did Foucault use biopower to say that modern governments control everything?

No. Foucault’s concept does not mean that governments exercise total control over every aspect of life. Biopower describes particular techniques and forms of power through which bodies and populations can be regulated, managed, normalized, or optimized. Foucault also emphasizes that power is relational and operates through numerous institutions, practices, forms of knowledge, and social relationships rather than existing solely in the state. His analysis therefore concerns how power operates through the management of life, not a claim that every aspect of human behavior is completely controlled.
