I don't think it's reasonable to expect anyone to match the demographics of the entire US unless they have a uniform presence across the entire US, such as one might find with Wal-Mart. It's a big country, and the people tend to aggregate into clumps.

Alphabet keeps about 1/4 of its people in Mountain View. In terms of the demographics of San Francisco metropolitan area, those diversity report numbers likely only slightly overrepresent whites and Asians. Statistically, it is unlikely that Alphabet/Google has a racial bias in hiring, but it certainly has a geographical bias for California.

I might bet a dollar--other than my bottom one--that the offices outside of California all feel like a small town in Silicon Valley.

But what demographics were used to target 50% females?

>Google is 54.4% white, 39.8% asian

it correlates well with what population looks like if you look at the percentiles of 750 Math SAT - 3% of whites, 20% of asian and 1% of the rest of race/ethnicity categories (like African American and Hispanic) make it there:

Multiplying by their representation in the overall population, 61% white, 6% asian and 33% for the rest , we can see that the representation at Google is a very close correlate : (3 x 61) / (20 x 6) / (1 x 33) = 183 / 120 / 33 vs. (54.4 / 39.8 / the rest about 6%)

The problem with your stats is that not very long ago, the term "white" essentially referred to a Protestant European. Didn't actually apply to Italians, Greeks, Jews, etc. So if history tells us something is that this will also change.

Also Google's CEO is noticeably anything but white.
