The provided graph shows the percentage of households owning different numbers of cars in Britain between 1975 and 2005.
Overall, households with 2 and 3 cars adhered to upward trends, with the former witnessing the most pronounced growth, whereas households without any cars were the only category that followed a steady downward trajectory. Notably, despite a temporary dip, the proportion of one-car households remained the highest throughout the period, eventually returning to its starting level.
Focusing first on the rising scenarios, somewhat similar trajectories can be observed. Starting off at just below 5%, the proportion of households with 3 cars rose slightly to about 6% in 1995 when the increase accelerated, ending the period at a high of close to 10% in the final year. The figure for families with 2 cars, on the other hand, began at approximately 7%, after which this figure doubled in the initial decade, followed by a period of stability until the year 1995. In the last decade, this figure increased negligibly, settling at around 18% by the end of the period.
Turning to the remaining figures, they followed identical downward trends in the first decade, albeit to varying degrees. Those without a car started at around 42%, a figure which then experienced a dramatic dip to exactly 25% in 1985, while the figure for households owning only one car decreased from 45% in 1975 to roughly 37% in 1985. From this point onwards, however, both figures followed distinctive patterns. The latter group increased steadily and bounced back to its starting point, hitting a peak of 45% in the last year. By contrast, the former persisted its drop further to just above 20% in 2005.
