This book was published in the autumn of 2014. In this dynamic subject that means that some of the statistics shown in the chapter could well be out of date by the time you read them.

a. Go online to see if there are any more up-to-date statistics.

b. Discuss your fi ndings. If there are no signifi cant changes, why is that the case? If there are changes, what are they and what has caused them?

c. Check the statistics against responses in your classroom for the same research. If you repeated the exercise with your friends or family are the results the same as with your classmates?
