Facebook has released its first ever Transparency Report, listing all the national governments that have requested access to information on its members. The report includes how many requests were made, how many users the requests affected, and how many resulted in data being handed over. US has by far the biggest number of Facebook users, with over 160 million at the end of 2012, more than half the total population of the country. US is the only country not to provide precise counts, so it is listed as having 11,000-12,000 requests about 20,000 US-based users.”]
