The provided bar chart illustrates the changes in the percentage of households with cars in a European country over three decades from 1971 to 2001.
Overall, there was a notable decrease in households without cars, a significant increase in those owning one car, and a moderate rise in households with two or more cars during the period under consideration.
In 1971, a substantial proportion of households, exceeding 45%, did not possess any vehicles. Conversely, ownership of more than two cars was limited to around 15%. The percentage of households without cars witnessed a steady decline, with a 5% decrease by 1981, followed by further reductions of over 10% in the subsequent two decades.
On the other hand, the ownership of at least one car began to rise in 1981, starting at 32% and peaking at 46% in 1991. However, this percentage experienced a slight downturn by 2001. The ownership of two or more cars fluctuated slightly over the years, without any substantial changes compared to other categories. Notably, single-car ownership experienced the most significant increase, reaching over 40% by 2001.
