A glance at the bar chart provided delineates the car possesion by households during the timescale of three decades, starting from 1971.
Overall, the data on households that didn’t have any cars triggered a downward trend while the two remaining families fluctuated to varying extents.It is clear that two cars ownership rate maintained the least position over the most period, except in 2001, when no car took the least.
Standing at roughly 50%, the proportion of one-car owners in 1991 was the highest, which was double that rate of car-less households in the same year, followed by the figure for two cars with more or less 21%, taking the smallest portion of this year. Furthermore, the year 2001 recorded a similar percentage in no-car owners and dual-car owners, which were approximately 30%, whereas households with just once car, again, occupied the top rank with virtually 45%.
In 1971 and 1981, no car held the highest percentage among the households, at roughly 49% and 42%, respectively. At the same time, the families which had a single car and dual cars accounted for approximately 34% and 18%, respectively, in 1971, after which the former dropped slightly to about 2% and the latter climbed substantially by 10%.
