Nationwide across the US, transit ridership is only at about 70% of where it was in 2019 before the pandemic. But this is not the case in all cities around the world. According to this recent Bloomberg article, Madrid, Hong Kong, and Paris are all above their 2019 ridership levels. Seoul and Shanghai are also close at just over 90%, and London is at 85%.

So this problem of fewer people riding transit seems to be a North and South American phenomenon. Rio de Janeiro is at 73%, Mexico City is at 70%, and San Francisco is somewhere near or at the bottom at 44%. The obvious explanations for this are that Europe and Asia are generally denser and less car-oriented, their return-to-office patterns have been much stronger (less WFH), and their governments probably care more about transit (and spend more money on it).

Broadly speaking, I think this is all true, but I'd love to know more precisely what's driving these differences. Because it's not exactly obvious. Consider, for example, Paris and London. Paris is at 103% of its 2019 levels, whereas London is only at 85%. Why is that? Both cities share a lot of similarities. They have a river that weaves through the middle, they're dense, they have lots of trains, and both are alpha global cities.

So why the delta? What exactly is Paris doing that is encouraging more transit usage?
