Bonding Networks vs Bridging Networks
"Those who study community life talk about two kinds of social network:
bonding and bridging. Bonding networks are those created within
homogeneous groups. While they can overcome social isolation, they can
also foster suspicion and prejudice, while limiting opportunities for change.
Bridging networks bring people from different groups together. Research
suggests that they can reduce crime and unemployment and, by enhancing
community voices, improve the quality of government."
