What social capital means
Social capital is not simply being friendly. It describes the relationships, trust, norms, and networks that help people coordinate, exchange support, and respond to pressure.
When a neighbourhood helps people find shelter after a disaster, when colleagues share information across an organisation, or when residents trust a local institution enough to participate, relationships are doing practical work. Social capital is a way to describe that work.
Two kinds of connection
Bonding ties connect people who already share an identity, place, family, profession, or experience. They can provide care, confidence, and rapid mutual aid. Bridging ties connect people across those boundaries. They can carry new information, introduce opportunities, and make cooperation possible between groups that do not usually meet.
Neither is automatically good. A tightly bonded group can protect its members while excluding outsiders. A bridge can connect communities, but it may be weak if it is not supported by trust or fair institutions.
Trust is useful but not enough
Trust is one part of social capital, not its complete definition. People also need repeated interaction, shared expectations, channels for communication, and some confidence that cooperation will not be punished. A community can be sociable and still lack access to decision-makers, public services, or material resources.
This is why social capital should not be used to blame communities for problems created by unequal housing, work, transport, or public investment. Relationships can help people navigate a difficult system; they cannot substitute for functioning institutions.
Why disasters reveal the system
During a crisis, formal organisations and informal networks interact. Neighbours may identify needs before a database does. Local groups may translate instructions, check on people living alone, or connect supplies to households. But recovery also depends on infrastructure, public coordination, funding, and the ability to include people who are isolated or newly arrived.
Measuring these connections is difficult. Counting memberships or volunteer hours captures activity but not necessarily trust, reach, or unequal access. Asking people about support captures experience but can miss those who are least connected. Good research therefore uses several indicators and explains what each one leaves out.
Social capital is most useful as a question about capacity: who can coordinate with whom, through which institutions, under what conditions, and with whose interests represented.
