The line graph illustrates sales of five different vehicle types in country A over three decades since 1990 with future predictions to 2020. In general, cars are more popular than vans and motorbikes, and sales of large cars and station wagons have dropped while those of smaller cars have dramatically increased.
In 1990, large cars over 1. 8 litres were the most popular vehicles sold, of about 2. 7 million. Sale of both these cars and station wagons followed the same pattern to a steady decrease, to a low of around million units in 2010. This falling in sales will continue to 2020. In contrast, smaller cars were less popular in 1990, by about 1. 8 million sold, but sales increased significantly in the decades from 2000 to 2010, to a peak of 3. 7 million. A smaller increase will expected in the next ten years.
Sales of both motorbikes and vans are remained steady at around 0. 5 million per year and will continue to do so over the period.
