Though I agree with your point, New Delhi and Delhi are not the same. New Delhi is a less dense area within Delhi that has many parks, government buildings, monuments and large suburban houses. There are areas of Delhi that are very dense. With any urban comparison, where you draw the border lines is essential and often difficult to do consistently.

An interesting thing to notice from your link, Union City, Guttenburg, and West New York (all in New Jersey) make the list while New York City does not. This is only because of how the lines are drawn.
