San Francisco • Twitter is acknowledging that it has been hiring too many white and Asian men to fill high-paying technology jobs, just like several other major companies in Silicon Valley.

The lack of diversity in Twitter's workforce of roughly 3,000 people was spelled out in data released Wednesday by the San Francisco company.

The breakdown revealed that 70 percent of Twitter's worldwide workforce is composed of men. In the U.S., nearly 90 percent of Twitter's workers are either white or Asian. Racial data wasn't provided for the global workforce.

Twitter's small number of women, black and Latino workers mirrors similar situations at Google Inc., Facebook Inc., Yahoo Inc. and LinkedIn Corp.

All of those companies have released their diversity data since late May.

Twitter Inc. is vowing to change its ways.
