The given line graph demonstrates the percentage of people who owned one to three cars, and those who did not own any car in the UK over a period of 30 years starting in 1975.
Looking at the chart, it is readily apparent that over the mentioned time span, owning two to three cars gained popularity, while owning no car and one car respectively experienced a nosedive in popularity and stayed the same. Another noteworthy feature is that despite the abovementioned fluctuations, there was no change in the ranks of the four categories throughout the period.
A closer look at the graph reveals that the proportion of one-car owners constantly took up the majority. Starting at 45% in 1975, it decreased and reached the lowest point of about 37% before recovering to the initial figure by 2005. Sharing the same trend at the beginning of the period was the figure for those who possessed no car, almost halving, from approximately 42% to 25%. However, it then continued to witness a decrease, though much less significant, from 25% to about 22% by the end of the period.
An opposite progression was recorded in the proportion of two-car and three-car owners, moderately increasing from 7% and 3% in 1975, to about 14% and shy of 5% by 2005, an almost twofold increase. However, by the end of the period, these were still the two lowest figures out of the four categories given.
