What are the ten priciest neighborhoods in the world?

Here is the list:

1. Kensington Gardens, London (by the way, few of the homes here are owned by Brits)

2. Jupiter Island, Florida

3. Belle Haven, Greenwich, Connecticut

4. Pacific Heights, San Francisco

5. Victoria Peak, Hong Kong

6. Sea Island, Georgia (apparently the wealthy live here, I never would have guessed)

7. Shibuya, Tokyo

8. Tribeca, in Manhattan

9. La Jolla (California, near San Diego)

10. The Seventh Arrondissement in Paris, which contains both Invalides and the Eiffel Tower.

You will notice that careful definition of a neighborhood is important.  Furthermore it is easy to have the riff-raff keep down your average.  Who would have thought that Tribeca would beat out the Upper East Side?

Thanks to Newmarks' Door for the pointer.  #1, 7, 8 and 10 appeal to me; I wouldn't live on #2 or #6 for any price.
