The line graph illustrates the percentage of households in Britain that owned different numbers of cars (no car, one car, two cars, or three or more cars) between 1971 and 2007.
Overall, households with no car declined steadily over the period, while the proportion of families with two cars increased significantly. One-car households remained the most common throughout, and ownership of three or more cars stayed low but gradually rose.
In 1971, around 48% of British households owned no car, making it the most common category. However, this figure decreased continuously, falling to just under 25% by 2007. In contrast, the percentage of two-car households rose from about 8% to roughly 26%, overtaking the no-car group by the mid-1990s.
Ownership of one car stayed relatively stable, starting at around 44% and fluctuating slightly over the years but remaining the dominant category. Meanwhile, the proportion of households with three or more cars remained low throughout the period, increasing only slightly from under 5% to about 8% by 2007.
In summary, car ownership in Britain increased overall during the period, with a noticeable shift from no-car households to two-car households, while single-car ownership stayed consistently high.
