Math fail

"disclosing that the majority of those workers are white males" - article

I would really like to see the math behind getting that from the data released. You can not meaningfully combine the 2 graphs to make a claim since they are about different sets of people. Is there some additional data that leads The Verge to think Yahoo employees are 80% white world wide even though they are only 50% white in the US?

The same mistake was made in the Google diversity article.
