Social networks — Sociology, 11–13 years
How connections between people shape the way information, help and opportunities move. Sociology, 11–13 years.
What a social network is
A social network is the web of connections around people, not just a website or app. Your family, classmates, neighbours and online contacts can all be part of it. Some links are close, while others are occasional.
Why sociologists study connections
People do not receive news, advice or help completely alone. Sociologists study networks to ask why one person hears about an opportunity quickly while another does not. The problem is that looking only at individuals can hide the connections that make a difference.
Following a message
Imagine Ana tells Ben about a free coding club. Ben tells two friends, and one tells Chloe. First, mark Ana–Ben; then mark Ben–the two friends; finally mark the link to Chloe. Chloe is three steps from Ana, so the network shows how news can travel through links.
A network is not a popularity score
It is tempting to say that the person with the most contacts is the most important. That is a reasonable mistake because counting is easy to see. But a network also depends on who is connected to whom, how close the links are and what moves along them.
Where networks appear
Networks matter when a school shares a lost-property notice, when neighbours organise a food collection or when friends recommend a club. Online platforms make links easier to see, but the idea also applies to face-to-face life. A connection can help information travel without guaranteeing that it is true.
