The bar chart compares sales of four music genres (pop, rock, jazz and classical) in the USA in 2010 across five age groups, measured in millions.
Overall, rock dominated sales among most age groups from 23 to 57, whereas pop was most popular only among the youngest group (16-22). By contrast, classical sales rose markedly with age and reached a peak among people aged 58 and over, while jazz showed the most stable pattern.
In detail, pop started at 4.8 million in the 16-22 group, then fell sharply to 2.5 million for those aged 23-31 and dropped further to 1.5 million in both the 32-45 and 46-57 groups, before recovering to 3.0 million among the oldest group. Rock followed a different trend: after a relatively low figure of 2.5 million in the youngest band, it climbed to 4.2 million in the 23-31 group and remained high at around 3.2-3.8 million until 57, ending at 3.1 million.
Jazz increased slightly from 2.0 to 2.9 million between the first three age groups, then edged down to 2.7 million and 2.0 million in the two oldest bands. In contrast, classical rose steadily from 1.8 million to 2.3 million up to age 57, before surging to 4.5 million in the 58+ group.
