This picture was presented by Elizabeth Churchill, Principal Research Scientist at Yahoo at a meeting I am attending today. It shows the privacy settings of a sample of a million Flickr users from 2005. Red spots note users who have photo sharing turned off (private), green shows users who have photo sharing turned on (public).
The results are fascinating. The US is widely public except for users who seem to be hovering around Utah, and varies by state. Europe, by contrast, is largely private, and more so as you move north. The Middle East is wide open. South East Asia is mixed. India is private.
