The given line graph indicates the percentages of households that possessed cars in the UK over a 36-year period.
Overall, it is obvious that the number of cars per household in Britain increased between 1971 to 2007. A redeeming feature is that the number of households with two cars rose significantly, while the number of households without cars decreased substantially.
In the year 1971, nearly half of total British households did not possess any car. Moreover, about 44% of households had one car, while only 8% had two cars. It was uncommon to have three or more cars, with almost 0% of households falling into this category at the beginning of the given period.
From the 1970s onwards, it was fairly common for each household to own one car, although there was little change in the figure for this category. The biggest change was recorded in the number of households with no cars, which fell dramatically during the timeframe to about 25% in the year 2007. Conversely, the figure for two cars witnessed a gradual rise of approximately 17% over a 36-year period, reaching a peak of 25% in 2007. In addition, the data for three or more cars remained unchanged in the first 6 years before growing steadily from 1979 to the end of the timeframe.
