The line graph delineates data on how car ownership in households in Britain during a period of 56 years starting from 1951. In general, the percentage of households without a car experienced a dramatical downward trend over the period, while the opposite was true for that of a gradual increase was seen in the figure for families with two and three cars or more. Notably, over the period recorded in a sharp rise in the first 15 years before remaining stable until the end of the period. It is evident that cars had become popular in households before 1975; the no-car trend was the highest trend at that time. From 1975 onwards, however, families possessing one car accounted for the largest choice.
In respect of the proportion of no car in households, it started at 85 percent and declined steeply to approximately 45 percent in 1975. After that, it went down further, ending at over a fifth.
As for those having one car, the proportion of these households began at just over one in ten, and then from 1951 to 1967 witnessed a considerable rise, with figures made up about 45 percent, nearly half of families in the UK in 1967. From this point onwards, the percentage of one-car families remained relatively stable at around 45 percent until the last year under research.
Concerning the ownership rates of families with two cars and at least three cars, they were both negligible at the beginning of the period. Thereafter, the fomer increased reemarkbly and reached a striking at 20 percent in the year 2007. If forecastion is correct, the use two cars in households will continue rising in the future. Menwhile, the latter also rose, after 8 years without fluctuation, but the rise is much slower, finishing at just under 10 percent.
