You'll have to add Portland and Seattle to that list as well as any city with a large university. If there is a large community of cyclists, there will be bike thieves working hard to separate them from their bikes.

I will grant you by virtue of there being more people in California and New York City, there will be more of everything. But for there to be $350,000,000 US worth of bicycles stolen every year (estimate is old) the problem is more common than you might think. https://priceonomics.com/post/30393216796/what-happens-to-st...

I'm in a suburb and had the seat stolen off a department store bike.
