The bar chart illustrates the sales distribution of a pharmaceutical company in four different regions, namely Asia, Europe and Africa, North America, and South America, between 2002 and 2006.
Overall, while the sales markets in Europe and Africa were consistently the highest among the four regions throughout the period surveyed, the opposite was the case for South America. Another striking feature is that an increase in the proportion of total revenues can only be observed in Asia.
44% of the sales volume in 2002 was Europe and Africa, the highest level for the drug company compared to other regions, after which it reached a peak of 48% of total sales in 2004. In the final two years, it witnessed a significant drop in sales distribution, ending with 40%. However, South America sales remained the lowest and fluctuated in the period surveyed, punctuated a slight dip in the middle of the period, at 6%.
Asia was the only region witnessing a remarkable increase in the percentage of the drug company’s total sales, with merely 12% of this company’s sales in 2002, before steadily increasing to peak at 28% by the end. This was mirrored by the figure for North America, which recorded a gradual decrease from 33% initially to 21% in 2006, overshadowed by the sales in Asia.
