The provided pie charts depict the proportion of books sold across five different genres(adult fiction, children’s fiction, biography, travel and others) by a particular bookseller in three separate years: 1972, 1992, and 2012.
Overall, adult fiction became the dominate genre by 2012, whereas the share of ‘others’ and biography categories fell considerably over the period. Children’s fiction and travel, meanwhile, remained relatively stable throughout fourty year span.
Adult fiction saw the most significant growth, rising from 20% contribution in 1972 to huge 45% by 2012, thereby becoming the best-selling genre by the final year. Children fiction also grew steadily, increasing from 20% sales share to 25% over the same period.
By contrast, the proportion of ‘others’ book sales nearly halved, dropping from 25% to 12%, while biography fell from 20% to just 8%. Travel shows a rise in percentage share from 15% to 18% between year 1972 to 1992 but could not sustain the growth and fell to 10% by 2012.
