From here:

(RNS) Alix Jules is an atheist, but for years he felt uncomfortable at gatherings of nonbelievers. The reason: he’s black.

“I got really tired of going back and forth to free thought events and being the only black person there,” said Jules, 36, who lives in Dallas. “It was not necessarily inviting. I just felt like an outcast … No one was reaching out to me.”

Last year, Jules helped launch a local initiative to address what atheists regard as an international problem for their movement: a lack of racial and gender diversity.

From the smallest local meetings to the largest conferences, the vast majority of speakers and attendees are almost always white men. Leading figures of the atheist movement — Richard Dawkins, Sam Harris, Christopher Hitchens and Daniel Dennett — are all white men.

The obvious conclusion is that most women and non-white men have too much sense to believe in the non-existence of God. Good for them.
