(AP) -- In a groundbreaking disclosure, Google revealed how very white and male its workforce is -- just 2 percent of its Googlers are black, 3 percent are Hispanic, and 30 percent are women.

The search giant said Wednesday that the transparency about its workforce -- the first disclosure of its kind in the largely white, male tech sector -- is an important step toward change.

"Simply put, Google is not where we want to be when it comes to diversity," Google Inc. senior vice president Laszlo Bock wrote in a blog.

The numbers were compiled as part of a report that major U.S. employers must file with the Equal Employment Opportunity Commission. Companies are not required to make the information public.

The gender divide is based on the roughly 44,000 people Google employed throughout the world at the start of this year. The company didn't factor about 4,000 workers at its Motorola Mobility division, which is being sold to China's Lenovo Group for $2.9 billion. The racial data is limited to Google's roughly 26,600 workers in the U.S as of August 2013.

Facebook chief operating officer Sheryl Sandberg recently said the social networking company is headed toward disclosure as well, but it was important to share the data internally first.

Apple Inc., Twitter, Hewlett-Packard Co. and Microsoft Corp. did not respond immediately to queries about possible plans to disclose data.
