The three diagrams illustrate the types of music albums purchased by people in Britain such as rock, classical and pop music, according to age and gender of people.
Bar charts describe the males, females and different age groups such as 16-24, 25-34, 35-44, 45+, and how many albums they bought in percentages. Actually, pop music and rock music have minimal differences between them, for instance, the age group of 45 plus people are more interesting in pop music than in rock, because 10% of them buy pop music albums and only 8% buy rock music ones.
Meanwhile, classical music has much more interested in 20% of 45+ age people and 16% of 25-34 age group, in contrast, other types of people who do not buy classical music albums such as teenagers and 35-44 old people, are less than 5%
Overall, the general tendency of purchasing albums is that in all 3 diagrams the number of males is higher than the number of females, and 25-34 and 45+ age groups are buying much more classical music albums than other age groups.
