Given are two pie charts which illustrate changes in the proportion of students who researched four different disciplines in an unnamed university from 1990 to 2010.
Overall, finance and linguistics became more prevalent, while art and mathematics Idque lost their preference among students. Notably, the biggest difference belonged to the percentage of people who studied languages over the period.
Regarding the only category that rose, 20% was the rate of finance researchers in 1990, four times as high as that of those studying linguistics which constituted 5%. Two decades later, there was a ten-percent increase in the former, while the latter also grew, but more dramatically, by 35%.
Concerning the categories with a downswing, mathematics students were the largest group with 60% at the beginning, significantly higher than that of those who learnt about painting at 15%. After twenty years, a three-fold decline could be observed in the first figure, while the second one also experienced a fall, but more slowly, of 5%.
