The bar chart illustrates the proportion of families who owned cars in a European nation from 1971 to 2001.
Overall, it is evident that the percentage of households with no car significantly reduced, while other categories fluctuated in the thirty-year period.
From 1971 to 1981, the proportion of families with no car slightly decreased, from less than 50% to approximately 40%, respectively. In contrast, the owner of one car accounted for more than 30% in 1971, then gradually grew to higher than 40% in 1981. Similarly, there was a slight rise in households with more than 2 cars, from around 25% to 30% in the same period, respectively.
In 1991, all categories experienced a decline, accounting for just over 30% for no car, under 40% for owners of one car, and approximately 25% for more than 2 cars. The proportion of no car owners remarkably declined to around 25% in 2001. In contrast, families with one car witnessed a significant growth to just under 50%. Likewise, families with more than 2 cars increased to nearly 40% in 2001.
