The bar graph illustrates the number of registered vehicles in Europe in 1996 and 2006 across five categories, along with their percentage changes over the period.
Overall, most types of vehicles experienced an increase in registration, except for motorbikes, which saw a decline, while public transport remained unchanged. Additionally, private cars had the highest number of registrations throughout the period.
Regarding the growing categories, the number of personal cars registered rose significantly from approximately 18 million in 1996 to around 24 million in 2006, marking a 26% increase. Although lorries increased less in absolute numbers (from around 1 million to nearly 2 million), they recorded the highest percentage growth at 50%. Similarly, unspecified vehicles grew by 33%, rising from about 2 million to roughly 3 million over the decade.
Concerning the remaining types, in contrast, motorbikes ranked second in 1996 with around 3 million registrations but declined by approximately one-third to 2 million in 2006. Finally, the number of registered public transport vehicles remained constant at approximately 1 million, making it the least common category throughout the period.
