What causes crime? Why are some people rich and others struggling for money? Are men and women really equal in society today? Why have youth cultures developed since the 1950s? Sociologists study these kinds of questions in order to understand and potentially change the world we live in. The most important reason for studying sociology today is that it is the best way of making sense of the complex and rapidly changing world. It will change your way of thinking and develop your understanding of yourself and the forces that shape your behaviour. It will allow you to question and challenge how we live and help you to understand social situations and human behaviour.
