most facebook users per city

Further to my last post on accelerating innovation, and after reading a post on Facebook users by country I thought a bit of research was pertinent. Based on my own survey using Facebook itself, here is a list of some of the cities with the highest percentage of facebook users:

• Montreal – 35.2%
• Sydney – 28.4%
• Toronto – 24.7%
• London – 22%
• Hong Kong – 18.9%
• New York – 17.4%
• Singapore – 14.1%

I had to remove from the list other potential candidates where Facebook didn’t breakdown their user base by city; cities in northern Europe and South America among them. Any feedback or inquiries on other cities are welcome.
