The graph illustrates the percentage of households in Great Britain with different levels of car ownership between 1971 and 2007.
Overall, the proportion of households with no car decreased steadily over the period, while ownership of two or more cars increased. The percentage of households with one car remained the highest throughout the period, although it slightly declined in the final years.
In 1971, around 48% of households did not own a car, which was the highest among all categories. However, this figure gradually fell over the years, reaching just above 25% by 2007. In contrast, the percentage of families with two cars rose significantly from about 8% in 1971 to approximately 26% in 2007, overtaking the “no car” category by the end of the period.
Households owning one car remained relatively stable, fluctuating between 42% and 45% across the period. Meanwhile, those owning three or more cars showed a slow but steady increase, starting at about 2% in 1971 and reaching just under 7% by 2007.
In summary, the data reveals a clear trend of increasing car ownership, especially in households with two or more cars, while the number of households without a car declined significantly.
