The pie charts illustrate the proportion of three types of vehicles: cars, trucks and SUVs in the years 1980, 1990, 2000 and 2010.
Overall, cars accounted for the largest share throughout the period, although their dominance declined significantly over time. In contrast, SUVs experienced a dramatic increase, becoming a substantial segment by 1980 and 1990, while the percentage of trucks fluctuated moderately.
In 1980, cars overwhelmingly dominated the industry, representing 95% of all vehicles, whereas trucks made up only 5%, and SUVs were not present at all. By 1990, the proportion of cars had fallen considerably to 79%. During the same year, trucks rose sharply to 15%, and SUVs appeared for the first time, accounting for 6%.
In 2000, the proportion of cars dropped to 54%. Meanwhile, SUVs saw a significant surge to 30%, overtaking trucks, which increased by only 1%. By 2010, the cars experienced a slight recovery to 58%, while SUVs decreased marginally to 28%. On the contrary, trucks declined to 14% on a small scale.
In conclusion, the data show a clear shift from the vast dominance of cars towards a more balanced distribution among vehicle types over the 30-year period.
