The graph given illustrates some data about the consumption of public transportation in a country by various ranges of age in different locations of citizens in 2016.
Overall, it is evident that individuals in megacities utilized public transportation significantly more than those in smaller cities throughout all age groups.
In megacities, around 40% of children aged 15 or younger used buses or other forms of public transport. This percentage increased dramatically for people aged 16-45, peaking at over 60%. However, public transport usage dropped sharply among adults aged 46-75, reaching a low of approximately 10%. On the other hand, the elderly population, aged 76 and above, showed a slight recovery in usage, with about 15% relying on public transport.
In contrast, in smaller cities, public transportation was much less popular. Fewer than 10% of children aged under 15 used public transport. The highest usage, at 20%, was established among those aged 16-30. For all other age groups, the proportion remained relatively stable, fluctuating around 10%.
