Saw this article in the newspaper, thought I’d share.

Since then, the subway added 10 billion more passengers every seven years, reaching 20 billion in 2000 and 30 billion in 2007. As of 2010, 1.48 billion passengers used lines 1 through 4 each year, which boils down to 4.04 million users a day.

The number of people using the Paris Métro, which started operating in 1900, stood at 1.15 billion in 2010, while the London Underground, which began running in 1863, has 868 million people using it every year. The New York Subway has 490 stations, four times more than the Seoul metro system, but has only 1.13 billion users per year.

Yep, it’s always full when I take subway in Korea for one year. I remember reading somewhere that it was 3 million riders a day but really it’s 4 million riders.
