The bar chart gives information about the proportion of residences with automobiles in a European country at 10-year intervals from 1971 to 2001.
Overall, car ownership exhibited a sharp decline in percentage of household without car, while this figure in possession of one or two cars saw a general increase. By the end of the surveyed period, the number of families with a single car had taken up the highest proportion.
As can be observed from the chart, in 1971, approximately a half of households did not own a car, making it by far the largest car ownership category. Meanwhile, around 35% of the total owned one, while the figure in two-car possession made up the lowest, registering a quarter of the whole.
In the following decades, the figure in carless families fell steadily and reached the bottom of roughly 30% in 2001, which nearly halved from 1971. In contrast, the proportion of one or two-car ownership recorded substantial increases in 1981 compared to that of 1971, with single-car possession becoming the highest. During the period from 1991 to 2001, these two figures rocketed and reached the peak in 2001, at over 50% and nearly 40% respectively.
