The bar chart illustrates the percentage distribution of a pharmaceutical company’s total sales across four regions – Asia, Europe and Africa, North America, and South America – between 2002 and 2006.
Overall, Europe and Africa accounted for the largest proportion of sales throughout the period, although their share declined slightly towards the end. In contrast, Asia experienced significant growth, whereas North America’s contribution decreased steadily. South America consistently represented the smallest share of total sales.
Europe and Africa generated 44% of total sales in 2002 and remained the dominant market, peaking at 45% in both 2003 and 2004. Thereafter, the figure slipped marginally to 44% in 2005 before falling to 40% in 2006. By comparison, North America’s share declined continuously from 33% at the beginning of the period to 21% by the final year.
Asia showed the opposite trend, with its proportion rising markedly from 12% in 2002 to 24% in 2005, before easing slightly to 22% in 2006. Meanwhile, South America contributed the smallest percentage throughout the period, dropping from 11% in 2002 to a low of 6% in 2004, before recovering to 12% by 2006.
