SAN FRANCISCO (MarketWatch) — Google Inc. disclosed on Monday that it complied with 94% of government requests for data about users of its services in the U.S. in the second half of last year, shedding some light on the Internet search firm’s behind-the-scenes interaction with law enforcement.

Google GOOG, +0.01% made the disclosure as part of its “Transparency Report,” an updated website detailing the scope of its interaction with government authorities.

When the transparency tool was unveiled last year, Google said it would provide updates to the information in six-month increments.

Google’s compliance with 94% of the roughly 4,600 government requests for user data in the U.S. compared to 72% compliance with 1,162 requests made in the U.K., for example, 76% compliance with 1,804 requests in Brazil, and 90% compliance with 72 requests made in Japan.

“The number of requests we receive for user account information as part of criminal investigations has increased year after year,” Google said in a statement. “The increase isn’t surprising, since each year we offer more products and services, and we have a larger number of users.”

Google noted that the data reflect requests received at Google and YouTube, the company’s online video service.

Google said its compliance rate reflects times where it produced “at least some” information, adding, “We review each request to make sure that it complies with both the spirit and the letter of the law, and we may refuse to produce information or try to narrow the request in some cases.”

Google did not disclose information about requests from the Chinese government for user data during the second half of last year — which followed the company’s decision to start routing traffic from mainland China through servers located in Hong Kong, in the wake of a censorship dispute.

Google operates the most popular search engine in the U.S. and many overseas markets, and offers a number of other services including email, documents tools and instant messaging.

According to data published recently by comScore, in May Google became the first web property to pass 1 billion unique visitors globally per month.
