Overall, it can be seen that the proportion of people who had more than two cars increased gradually while the figure for those with no cars decreased sharply. Besides that, the percentage of owners had one car remained relative unchanged and was still the highest figure during 30 years, while the figure for those who had two or three cars was the lowest.
Looking at the details, as for the proportion of the population possessing a car hit the top, started at 45% in 1975. Five years later, the figure for those had a downward trend, presenting the negative change of this trend, about 37% but after that the percentage of people owning a car returned to 45%. The figure for those had no cars fell sharply from around 43% to 25% and continued to grew down slightly between 1985 and 2005, ending about 23%.
In contrast, the opposite changes can be seen from the proportion of the British people had two or three cars. Stood at about 7%, the figure for those had two cars grew up after five years, and stopped at 17% in 2005. Druing 30 years, the percentage of owners had three cars increased slightly, stood at 3% and still gradually increased over time, in 2005 the figure for those ended at about 8%.
