Level of analysis in the context of "Modern humans"

Humans, scientifically known as Homo sapiens, are primates that belong to the biological family of great apes and are characterized by hairlessness, bipedality, and high intelligence. Humans have large brains compared to body size, enabling more advanced cognitive skills that facilitate successful adaptation to varied environments, development of sophisticated tools, and formation of complex social structures and civilizations.

Humans are highly social, with individual humans tending to belong to a multi-layered network of distinct social groups – from families and peer groups to corporations and political states. As such, social interactions between humans have established a wide variety of values, social norms, languages, and traditions (collectively termed institutions), each of which bolsters human society. Humans are also highly curious: the desire to understand and influence phenomena has motivated humanity's development of science, technology, philosophy, mythology, religion, and other frameworks of knowledge; humans also study themselves through such domains as anthropology, social science, history, psychology, and medicine. As of 2025, there are estimated to be more than 8 billion living humans.

A community is a social unit (a group of people) with a shared socially-significant characteristic(s), being place, set of norms, culture, religion, values, customs, or identity. Communities may share a sense of place situated in a given geographical area (e.g. a country, village, town, or neighborhood) or in virtual space through communication platforms. Durable good relations that extend beyond immediate genealogical ties also define a sense of community, important to people's identity, practice, and roles in social institutions such as family, home, work, government, society, or humanity at large. Although communities are usually small relative to personal social ties, "community" may also refer to large-group affiliations such as national communities, international communities, and virtual communities.

In terms of sociological categories, a community can seem like a sub-set of a social collectivity.In developmental views, a community can emerge out of a collectivity.

Audience theory offers explanations of how people encounter media, how they use it, and how it affects them. Although the concept of an audience predates modern media, most audience theory is concerned with people’s relationship to various forms of media. There is no single theory of audience, but a range of explanatory frameworks. These can be rooted in the social sciences, rhetoric, literary theory, cultural studies, communication studies and network science depending on the phenomena they seek to explain. Audience theories can also be pitched at different levels of analysis ranging from individuals to large masses or networks of people.

James Webster suggested that audience studies could be organized into three overlapping areas of interest. One conceives of audiences as the site of various outcomes. This runs the gamut from a large literature on media influence to various forms of rhetorical and literary theory. A second conceptualizes audiences as agents who act upon media. This includes the literature on selective processes, media use and some aspects of cultural studies. The third see the audiences as a mass with its own dynamics apart from the individuals who constitute the mass. This perspective is often rooted in economics, marketing, and some traditions in sociology. Each approach to audience theory is discussed below.

Health politics or politics of health is an interdisciplinary field of study concerned with the analysis of social and political power over the health status of individuals.

Health politics, incorporating broad perspectives from medical sociology to international relations, is interested not only in the understanding of politics as government or governance, but also politics as civil society and as a process of power contestation. It views this wider understanding of politics to take place throughout levels of society — from the individual to the global level. As such, the politics of health is not constrained to a particular area of society, such as state government, but rather is a dynamic, ongoing social process that takes place ubiquitously throughout our levels of society.
