What is the social environment?

Social Environment Definition and Examples

The social environment includes the relationships, institutions, cultural practices, and material conditions in which people live. It extends beyond the people nearby to employment, services, inequality, and power relations.

Relationships: family, friends, colleagues, and the expectations present in everyday interactions.
Institutions: schools, workplaces, public services, and the rules that organize access to them.
Culture: shared values, customs, and practices in a group or community.
Material conditions: housing, transport, and access to resources, which connect the social environment with the physical environment.

Some everyday examples:

A new employee wants to walk at lunch and joins colleagues who already do so. Their shared routine makes it easier to take part.
Two students have similar ability and motivation. One has family members who can help with college applications; the other must find that help elsewhere.
A neighborhood has a well-used community center with evening classes. Residents have more places to meet people and learn skills.
A workplace praises careful documentation but promotes the people who close work fastest. The spoken norm and the reward system point in different directions.

These examples are illustrations, not study findings.

Different levels

Barnett and Casper describe social environments as changing systems shaped by history. They can be studied at several connected levels: households, networks, neighborhoods, regions, and larger economic structures.

Social and physical conditions overlap. Housing and transport, for example, reflect decisions about policy and investment.

The socioecological model organizes these levels for public health work, from individuals and relationships to organizations, communities and policy.

What the research shows

Two lines of research show what the concept adds: outcomes can differ with the people and places around someone, not only with that person's own traits.

Social relationships and survival: a meta-analysis of 148 studies with 308,849 participants found that people with stronger social relationships had higher odds of survival during follow-up (odds ratio 1.50) (Holt-Lunstad, Smith and Layton, 2010). The studies were observational. They show a strong association, not proof that relationships caused the difference.
Neighborhoods as an experiment: in the Moving to Opportunity study, families living in high-poverty public housing were randomly assigned to one of three groups: an offer of a housing voucher usable only in a low-poverty neighborhood, an offer of a standard voucher, or no offer. In follow-up surveys in 2008–2010, women in the restricted-voucher group had lower rates of extreme obesity and diabetes than the control group (Ludwig and colleagues, 2011). Children in that group who were young when their families moved later had higher college attendance and earnings, and the gains declined with the child's age at the move (Chetty, Hendren and Katz, 2016).

Moving to Opportunity did not have one uniform effect. Results differed by outcome and by participants' age. The study found substantial long-term benefits for younger children whose families were offered restricted housing vouchers; results for adolescents were less favorable and often inconclusive. Moving changed several conditions at once, so the study cannot identify which specific neighborhood features produced the results.

In the Behavioral State Model, a framework developed by Jason Hreha for diagnosing possible constraints on a specific behavior, the Social Environment is one of two context components, alongside the Physical Environment. It includes other people, relationships, norms, observed behavior, support, sanctions and the coordination structures around the behavior. The model's components are prompts for inquiry; the model is a developing practitioner framework, not a validated psychological test.

Why it matters

“The environment matters” is a starting point, not a complete explanation. Identify which features matter for the behavior you are studying and how they affect the people involved. Individual characteristics and circumstances still need attention.

In applied behavioral science, ask concrete questions: Does a work schedule allow the intended activity? Do group expectations support it? Can people reach the service? These questions turn a broad description of the social setting into features that a design team can investigate.

The same behavior can be easy in one social setting and hard in another, which is one reason person–environment fit matters. Changing who is around and how people interact can itself make a behavior easier: see restructuring the social environment and social norms.

A design change may help with a particular task without solving the larger conditions that constrain it.
