Band 9: The table below shows information about metro systems in six different cities. Summarise the information by selecting and reporting the main features and make comparisons where relevant.

The table provides data on metro systems in six cities, comparing their network size, passenger volume, and ticket costs.

Overall, metro systems with larger networks do not necessarily have higher passenger numbers or fares. Notably, Beijing and Tokyo have the busiest systems, while London has the most expensive tickets despite a smaller network.

New York has the largest metro system, with 24 lines spanning 659 miles, yet its annual ridership (1.65 billion) is significantly lower than Tokyo (3.1 billion) and Beijing (3.6 billion), despite those cities having shorter networks. London, with only 11 lines and 249 miles of track, charges $7.30 per ticket, making it the most expensive system.

In contrast, Mexico City has the cheapest fare ($0.23) but still accommodates 1.6 billion annual journeys, surpassing London. Paris has the shortest network (127 miles) yet records 1.5 billion trips annually.

This data suggests a loose correlation between affordability and ridership, with Asian metros handling the most passengers at lower fares, while Western systems tend to have higher costs and fewer passengers.
