The bar chart illustrates the proportion of families who owned cars in a European nation from 1971 to 2001.
Overall, the percentage of households that did not own any cars decreased significantly over the 30-year period. By contrast, the figures for families with one car and those with two or more cars both experienced an upward trend despite some fluctuations.
In the first decade (from 1971 to 1981), the proportion of households without a car decreased slightly, while the figure for families owning two or more cars rose quickly from nearly 16% to 27%. Meanwhile, the percentage of one-car households stayed relatively stable, dropping only by roughly 3% during this period.
Between 1981 and 1991, families who owned one car saw rapid growth, rising from 32% to 42%. In contrast, the no-car category declined quickly by about 12% and continued to drop until 2001. From 1991 to 2001, the percentage of households with two or more cars increased further, eventually reaching a point where it balanced out with the other categories.
