The line chart illustrates how the data about the proportion of families who used cars for daily usage in the UK changed over a 36-year period, commencing in 1971.
Overall, it can be seen that the ownership of 2 cars and 3 or more cars increased, whereas those who had no car and one car decreased. Further, the owner of one car minimally fell.
Looking at the chart in more detail, the number of households that used two cars stood at around 7.5% in 1971. By 2007, it had risen to about 26%, which was the highest increase in the chart. The ownership of 3 and more cares
climbed from approximately 1.5% in 1971 to about 7% in 2007, which is the lowest value in the graph.
Turning to the remaining date, it is seen that the use of no cars by families was more or less 47.5%, which was the climax value on the chart, and this figure declined to around 25% in 2007. Furthermore, family use of one car showed fluctuation, but it was slightly reduced from approximately 44% in 1971 to about 43% in 2007.
