The US government asked Google for user information 4,287 times during the first six months of 2010.
During the same timeframe the UK government put in over 1,000 such requests.
This is just two snippets from Google’s new Transparency Report, a set of tools designed to show censorship levels around the globe.
Civil liberty groups welcomed the tool but called on Google to provide even more detail about the requests.
Earlier this year, Google released details about how often countries around the world ask it to hand over user data or to censor information.
The new map and tools follows on from that and allows users to click an individual country to see how many removal requests were fully or partially complied with, as well as which Google services were affected.
