[Marvel] Are all major cities full of superheroes or New York an exception?

New York City is the home to Spider-Man, Daredevil, the Fantastic Four, Dr. Strange, and countless others. Do cities like Los Angeles, Chicago, London or Paris boast a high number of super powered individuals or heroes?

You're not wrong in your perception that New York is unusually superhero-dense. Even characters in-universe note how odd that is. But to be fair, New York is generally pretty trendy. 

There have been a few teams based on the West Coast, such as the Champions of Los Angeles. Both Daredevil and Iron Man briefly moved to San Francisco in the Marvel NOW era, the former while sort-of under witness protection. 

The Avengers also opened up branch teams for both the West Coast and for the Great Lakes region (we don't talk about those guys). Also, Kaine, the v~~illainous~~ um... "conflicted and confused" clone of Spider-Man, once set up shop in Houston after noticing there were no other heroes there. 

And following the SHRA, government oversight established the Fifty-State Initiative, so that each of the United States would have its own super-team. This was basically going too far in the other direction (how many supervillain attacks do you think Rhode Island gets, realistically?), and a lot of these teams have basically faded into obscurity. And the one in Florida got eaten by zombies. Yeowch. 

But this became a real plot point in Secret Empire, when all the heroes in New York and outer space were taken by surprise and weren't able to stop the bad guys from taking Washington DC.
