A nicely executed interactive map of total annual passenger entries into the Paris Metro system. “Entries” are simply defined as a ticket validation at the relevant station.

Even in my static screenshot, the enormous quantities of people that enter the Metro at the main railway stations of Paris – the Gare du Nord, Saint-Lazare, Gare de Lyon and Montparnasse-Bienvenue – can be clearly seen. There’s a staggering 48 million entries each year at the Gare du Nord alone!

I definitely recommend clicking through to view the full interactive experience: there’s full information for each line and station of the Paris Metro – fascinating stuff!
