The bar chart provides information about the proportion of a car manufacturer’s total revenue in different areas between 2006 and 2010.

It is clear that while the sales of cars in Asias increased significantly, that of Europe and South America generally decreased. In addition, despite some fluctuations, the percentage of car sales in South America remained the same level.

In 2006, starting as the third biggest market, Asia contributed only a quarter of the total revenue. However, the figure for Asia sharply rose and doubled itself in the course of 4 years, reaching 50% by 2010. In contrast, that of North America, despite ranking second at the start of the surveyed timeframe with 30%, gradually reduced to 9% by the end of the period.

From 2006 to 2008, while the percentage of car sales in Europe grew by 4%, that of South America dwindled by 6%. Car revenue in Europe then decreased to 34% by 2009, no longer being the biggest market for the car company as this percentage was lower than that of Asia, with 42%. By the same year, the car revenue of South America continued to dip to 5% before recovering to the original level at 11%.
