A collective behaviour can be described as “a collection of unwritten rules and norms followed by a group of people who share common beliefs, values, and interests, with the goal of inter-stimulation”. An example of a group that falls under this category are gangs. Gangs are kind of like a small organized group of offenders. People may join a gang because they feel accepted in that group, their friends are in it (or peer pressured them to also join), they enjoy being rebellious, they are curious to what people in gangs might do, or they are bored and are looking for something interesting to do. The gang might also run in that person’s family or neighbourhood, and they might be forced to join. A person might also join a gang to get access to things, such as drugs and alcohol. In a gang, I believe there are a set of unwritten rules that the members kind of have to follow. These rules are probably put in place by the member who has the most power or whoever is the leader. I also think that the rules are probably different for each gang. I would imagine that the rules are probably very strict. After I did some research, I found that there are approximately 7,000 youth gang members in Canada. Saskatchewan has the second highest gang population with 28 youth gangs and 1,315 members. The facts I stated earlier were from 2002, and in 2002 Canada’s population was roughly 35 million. So therefor, approximately .023% of people living in Canada are apart of a youth gang, which is also 1 in every 5,000 youths. And I feel like that’s not too bad, it could be much worse. Furthermore, gangs portray certain behaviors. These behaviors may be committing crimes (stealing vehicles, doing/dealing drugs, own guns illegally), arrogant and defiant attitude, trying to be intimidating, respecting the people in your gang (especially the leader), retaliation, helping their fellow gang members, and being loyal to your gang.
