A support network is the group of people, organisations and relationships that provide or can provide practical, emotional, informational or social assistance to an individual. It can include relatives, friends, partners, neighbours, colleagues, professionals, community organisations, peer groups and online communities. A support network is therefore broader than a single helper and can contain different relationships serving different purposes. One person might provide emotional encouragement, another transport, another specialist advice and another emergency assistance.
Networks vary in size, strength, accessibility and reliability. A large network is not necessarily a strong network because relationships can be superficial, conflictual or unavailable. Conversely, a relatively small network can provide substantial support when its members are trusted, responsive and able to meet relevant needs.
Support networks contain different types of ties. Strong ties often involve close family members, partners or longstanding friends and may provide emotional intimacy and substantial practical help. Weak ties, such as acquaintances, colleagues or community contacts, may provide less emotional support but can provide information, opportunities and connections to resources that are not available within a close circle. Social network theory examines characteristics such as network size, density, centrality, reciprocity and the distribution of ties. These concepts help explain why two people with the same number of contacts can have very different access to support. A network can also change over time as relationships develop, weaken, end or become more important because circumstances change.
Support networks can provide emotional support through listening, companionship, reassurance and encouragement. They can provide instrumental support through transport, meals, childcare, household assistance, financial help or help navigating daily tasks. They can provide informational support by sharing knowledge about services, employment, education, healthcare or practical problems. Networks can also provide advocacy when someone needs another person to communicate with institutions or help them understand their rights and options.
Different needs require different network capacities, which is why network assessment should not focus only on whether a person has someone to contact. The relevant question is whether the network can provide appropriate support at the required time and in a form the individual finds acceptable.
Support networks are particularly important during transitions and crises. Moving home, starting education, becoming a parent, experiencing unemployment, managing disability, recovering from illness, experiencing bereavement or entering older age can alter existing relationships and create new support requirements. A person may temporarily require more intensive support than their network normally provides. Networks can also become weaker through geographic relocation, relationship breakdown, retirement or social isolation. Building connections before a crisis can therefore increase resilience, although people should not be blamed when circumstances leave them without adequate support. Formal organisations can sometimes help expand a network by connecting individuals with peer groups, community activities, professional services and other sources of assistance.
A support network can include formal and informal relationships. Informal networks are based primarily on personal relationships and may include family and friends, while formal networks include professionals, voluntary organisations, support groups and public services. Informal relationships often offer trust and continuity, whereas formal services can provide specialist knowledge, safeguarding and structured assistance. The two systems can complement one another. For example, a person may receive emotional support from friends while relying on a professional for specialist advice and a community organisation for practical assistance. Effective support planning therefore considers the whole network rather than assuming that either family or professional services alone can meet every need.
Networks can contain unequal power and obligations. A person providing substantial care may experience stress, financial pressure or reduced time for other activities, while a recipient may worry about becoming dependent. Healthy networks therefore require communication about boundaries, consent and realistic expectations. Support should not automatically mean taking control of another person's decisions. Where someone is capable of making their own choices, good support generally helps them exercise autonomy rather than replacing it. Safeguarding considerations become especially important where there is vulnerability, coercion, abuse or significant dependency. Network strength must therefore be assessed alongside relationship quality and safety.
Digital technology has expanded the possible geographical reach of support networks. Messaging services, video calls, online groups and social platforms can allow people to maintain relationships across cities or countries and can connect people with others who share particular experiences. Online networks can be especially useful where local communities are small or where a person has difficulty travelling. However, digital support may not provide physical assistance, and online interactions can also involve misinformation, harassment or unreliable relationships. The most effective network may therefore combine digital and face to face relationships according to the person's circumstances and preferences.
A support network should be understood as a living social system rather than a fixed list of contacts. Its usefulness depends on who is connected, what resources they possess, how willing they are to help, how accessible they are, how relationships interact and whether the network can adapt when circumstances change. Mapping a support network can help identify strong relationships, gaps, duplicated responsibilities and potential sources of assistance. It can also reveal that someone has many contacts but lacks a trusted person for a particular need. Understanding networks in this way helps explain how social relationships translate into practical resources, emotional security, information and opportunities for participation.
