The presented line graph illustrates the proportions of British citizens categorised by the number of private automobiles they possess over a period between 1971 and 2007.
Overall, what stands out from the graph is that the percentage of people having no car declined significantly over the period in question, while those who own two cars exhibited an opposite upward trend. Another interesting point is that the portion of single car owners only fluctuated mildly.
Looking at the details, in 1971, people with no car, by far, registered the highest percentage of around the half of people, which was slightly higher than those owning one car that recorded approximately 44%. In contrast, both of those having two cars or three cars onwards made up less notable proportions of around 7 % for the latter and a mere 1 % for the former. Over the next two decades, citizens having no car dropped considerably to a one-third, while those with two cars or more soared consistently, with a slight increase for those having three or more vehicles.
In 2007, no car owners stood only at a quarter, whereas those having two cars overtook this number by recording slightly above the quarter. The other categories had either remained stable or increased minimally by the end of the period.
