In the second half of 2009, U.S.-based data requests numbered 3,580. By the first half of this year, that number had risen to 10,918 — a 205 percent increase. That pattern is also reflected globally, though to a lesser extent. Over the same period, international data requests on Google users roughly doubled.
For the first time, Google has also offered a detailed breakdown of the kinds of requests it receives. Previous reports simply divided the requests up into subpoenas, search warrants and an amorphous category called "Other." Now, the company distinguishes among wiretaps, pen registers and disclosures made in connection with life-threatening emergencies.
