The line graph gives information about the number of car owners, in four distinctive categories, including: who had 3, 2, 1, and no cars, in the UK between 1975 and 2005.
Overall, it can be observed that the number of individuals who had 1 car dominated among others over time, while 3 car owners were the smallest number. Meanwhile, the number of all the mentioned groups increased over 30 years, except for individuals who had no car.
In 1975, the number of 1 car owners stood at 45, experiencing a steady decrease to under 40 in 1985, then increased gradually, reaching its initial number over a 20-year period. In contrast, the number of people who had 3 cars was the smallest compared to others. It began at approximately 3 in 1975, increasing steadily to around 9 by 30 years.
Furthermore, the number of 2-car owners started at around 7, rising to under 15 in 1985, increasing gradually to around 15 in 1995, then it increased sharply to approximately 18 in 2005.
By contrast, in 1975, the majority of people, around 43, had no cars, which their number decreased notably to around 25 over 10 years. After that, it remained almost unchanged until around 1990, and then decreased gradually to approximately 23 in 2005.
