The line graph illustrates the trends in car ownership amongst British households from 1971 to 2007, categorized by the number of cars per household.
Overall, the graph reveals a significant increase in car ownership in Britain over the period presented, with a notable rise in the number of households owning two cars and a corresponding decline in those without cars.
In 1971, car ownership was relatively low, with nearly half (48%) of British households having no car at all. Conversely, 42% possessed just one car, and only a small percentage (7%) owned two cars. Households possessing three or more cars were even less common, making up only 3% of the total.
Over the subsequent decades, car ownership witnessed a substantial transformation. The proportion of households with no car declined steadily, reaching approximately 25% in 2007. Concurrently, the percentage of households with two cars rose consistently, reaching nearly 22% in 2007. Although the proportion of one-car households remained relatively stable throughout the period, reaching a peak around 1980, the number of families owning three or more cars also increased considerably, reaching around 5% in 2007.
