For example, Intel is #47 and in mid-2017 they were only 801 employees away from full representation.
From their report:
> Full representation means that Intel will be at market availability or higher by 2020 for every employee job category that we track; both technical and non-technical, for women, African Americans, Hispanics, and Native Americans.
At the same time, they state that white males and Asians comprise >90% of mid to senior technical roles.
So I take these two facts together to mean that the number of under-represented folks on the market is quite small. Of course you're at 50-75% Asian employee population, because that's representative of the pool you're drawing from.
