The graph shows the actual and predicted percentage of car ownership in one country. Actual numbers come from 1955, 2005, and 2015, while predictions for the year 2025 are shown.
It can be seen that over the period, the greatest percentage of car ownership is that of people that have one car. Greatly surpassing other categories in 2015. However, that number is predicted to drop at 2025 from more than 40% to less than 30% of the population. In the next category, the number of people who have no car has been steadily decreasing from 1995 to 2015. Differing until more than 15% to the population of people owning one car, but this situation I predicted to change in 2025, with the population of people owning no car rising to slightly more than 30%, while the other drops to slightly less than 3%.
In contrast to the steadily declining percentage of people with no car from 1995-2015, the percentage of people with two or more cars are steadily rising and even predicted to rise until 40% of the population, replacing the population of people with one car as the greatest category or car ownership in a country.
Therefore, it can be concluded that something happened between the year 2015 and 2025, that caused the number of people without a car and the ones with two or more cars to rise by around 10%, with the people owning one car to drop by more than 10%.
