The line graph illustrates data about car ownership in the UK over the course of 30 years, from 1975 to 2005.
Overall, it is evident that the share of people who owned two cars increased markedly, while the percentage of people who did not possess a car halved. Notably, people who owned a car remained the largest group over the given period. Additionally, despite a fourfold increase, people who possessed three cars made up the smallest proportion throughout.
Starting at approximately 7%, people who had two cars then increased consistently to nearly 15%. Following this, they continued their upward trend, albeit at a less pronounced rate. By contrast, the reverse was true for people who did not have a car. They stood at virtually 45% in the initial year. Subsequently, they dropped sharply to 25% in 1985. They then decreased gradually and slowly to just over 20%.
Regarding those who did not change their ranks, people who owned a car decreased considerably to roughly 38% from 45%. They then increased and recovered, however, they could not surpass their initial level. Conversely, people who owned a car accounted for the smallest share. They started at 3% and subsequently recorded a steady growth to nearly 9% at the end of the timeframe.
