The graph illustrates the percentage of households owning cars in Britain from 1971 to 2007, with data presented in four-year intervals.
Overall, it is clear that almost all car ownership experienced an increase over the period of 36 years, except for households without cars. The percentage of one-car owners remained almost the same throughout the period, while the two-car and three or more-cars households experienced the most significant growth in car numbers.
Focusing on higher percentage of car ownerships, in 1971, there were approximately 7% of households having two cars, this number rose steadily before reaching around 25% by 2007. It was not popular for households to have three or more cars in 1971. It started around 1% in 1971, increasing gradually over the years before ending at around 6% by 2007.

The single-car households started at around 44% in 1971, it fluctuated slightly but stayed close to this figure throughout the years, ending at approximately 43% in 2007
