According to the data Omnicom does disclose, women make up 54 percent of U.S. managers in 2015. Multicultural professionals make up 18 percent of managers. And overall, 28 percent of Omnicom's talent base is multicultural. Much of that is to the credit of Tiffany R. Warren, who has been doing diversity and inclusion work for the company for six years as its chief diversity officer. Warren said this has been "a great year" for diversity both in commercials and in the industry. She said her priority is to solve the issue as an industry, something she says the technology world actually doesn't do.
