Fair enough. I didn't find a ready source on average camera densities by country, but comparing cities at the link below can give a sense of the difference. London has 399 cameras per square kilometer. Beijing has 278. NYC has 26, so not quite as Orwellian, in terms of cameras at least.

Approximate Populations, per wikipedia, for reference:

  London:   9 million  
  Beijing: 21 million  
  NYC:      9 million
