Read the following case study and answer the questions that follow for this section: South African students spent 15% more than the average consumer, according to the Student Spending Report, released in Johannesburg this year. Whereas households contributed R1.86-trillion to consumer spending, students have increased their share from R33-billion to R39.5-million in a year. A large portion of the students' money (78%) came from parents and other relatives. About a quarter of their income was earned from part-time work and 18% came from bursaries and sponsors. The Student Village study in May and June was based on the responses of 681 students aged between 18 and 24. Student Village CEO Ronen Aires said the survey would help companies improve their marketing to students. "Clothing, retailing and fashion are high value drivers for students and with this knowledge marketers can target their efforts correctly," Aires said. About 30% of students' money is spent on rent, followed by food and groceries, which at R556 a month, is about 16% of their R3510 monthly expenditure. At least R254 is spent on entertainment and R250 on alcohol. Students spent about R128 a month on contraceptives. Black students spent more on toiletries and cosmetics, take-away meals, gadgets and extra tuition; White students spent more on food, groceries, holiday travel, entertainment and alcohol; and Coloured students spent more on cigarettes, bling, magazines, clothing and footwear.
