The bar charts give information about the proportions of car owners in a European country from 1971 to 2001. Overall, while more households own one or two cars, there is a decrease in the number of people who did not have car over a period of 30 years.
In 1971, those who bought no car had a disproportion compared to two other groups, at 50%. The figure markedly decreased to over 40% in the next 10 years and continues to decline by 11% to 30% in 1991. It stayed unchanged until 2001.
Among three groups, the one of households with one car experienced the biggest increase over the given period of time. The figure was just 35% in 1971 and saw a slight decline of about 3% in 1981. However, it gained a peak of 50% in 1991 and then decreased to over 40% in the next 10 years, higher than the percentage of owners without cars.
Those who purchased two cars in 1971 made the most modest contribution with only 18%, but it achieved a considerable growth to stand at proximately 29% in 1981. The percentage then contracted by roughly 7% in 1991 and regained the highest point of 30% which was equal to the group of non-car owners at the end of the period.
