Steve Bannon, Donald Trump’s chief strategist, said last year that people from Asia or South Asia are heavily represented in CEOs in Silicon Valley:
When asked if he agreed, Bannon responded: “When two-thirds or three-quarters of the CEOs in Silicon Valley are from South Asia or from Asia, I think . . . ” he didn’t finish his sentence. “A country is more than an economy. We’re a civic society.”
The Huffington post cites a study an organisation called the Ascend Foundation to say that the number is much smaller. However, I haven't been able to find any independent studies corroborating with this. The introductory section of the study cites another study that Asians are under-represented, but it's also by the Ascend Foundation.
It should go without saying that whether Bannon's comment is true is separate from whether it's relevant, but are two thirds of CEOs in Silicon Valley from South Asia or from Asia?
