What is Social Network Analysis (SNA)?
Social Network Analysis (SNA) is a method for mapping and measuring relationships between people, groups or organisations to reveal how information, influence and support flow through a community. It turns connections into visual maps and simple metrics that help you find key connectors, clusters and communication gaps.
Social Network Analysis looks at who is connected to whom and how strongly. In SNA, individuals or organisations are represented as nodes, and the relationships between them (friendship, communication, referrals, membership) are represented as ties. By analysing the pattern of ties you can identify central people who reach many others, tightly connected subgroups, bridges between communities, and isolated people or groups who may be missing from outreach. SNA works with different data sources: survey responses naming contacts, attendance lists, referral logs, or digital interactions — and it is useful whether you’re studying online networks or in-person community relationships.
Usage example
A local council runs a consultation and includes a short question asking residents to name community groups or neighbours they rely on for information. Using SNA on those responses, the council discovers a small number of community leaders who connect otherwise separate language groups. The council sends targeted outreach and translated materials through those connectors to improve participation among underrepresented language communities.
Practical application
SNA matters because it helps you reach the right people, not just more people. Practical uses include: identifying trusted messengers who can boost survey spread across language communities; discovering clusters where a single translation or tailored message could reach many people; spotting isolated groups who need direct outreach; evaluating whether outreach channels are actually connecting different language communities; and measuring whether interventions increase cross‑community connections over time. For teams with limited translation budgets, SNA helps prioritise where translations and localised outreach will have the greatest impact on inclusive participation.
FAQ
What data do I need to do Social Network Analysis?
You need information about connections: who interacts with or trusts whom. That can come from survey questions that ask respondents to name contacts or organisations, event attendance lists, referral records, or digital interaction logs. Even a single well‑designed question (e.g. “Who do you ask for local information?”) can produce useful SNA insights.
Is SNA just social media analysis?
No. SNA is a technique that applies to any network of relationships, online or offline. While social media data is one source, SNA is equally useful with in‑person networks — neighbours, community groups, service referrals — which are often more relevant for public consultations and multilingual outreach.
How can SNA improve multilingual engagement and survey response rates?
SNA helps you find community connectors who can share translated surveys or explain them in person, shows which language groups are connected or isolated, and indicates where a small number of targeted translations or trusted messengers will increase reach. That makes limited translation resources more effective and helps close participation gaps across languages.
Are there privacy or ethical concerns with SNA?
Yes. Network data can be sensitive because it reveals relationships and may identify individuals as connectors or isolated. Collect only what you need, explain why you’re asking for contact or connection information, obtain consent, anonymise or aggregate results where appropriate, and follow data‑protection rules relevant to your organisation and participants.
