Racial Dating trends

I've started to notice quite a few white females with non-white males. Basically 2/3 of white females I see out and about are with non-white boyfriends (asian, brown, etc).

No, these people aren't just friends, they are clearly boyfriend-girlfriend.

Other groups of females generally stay with their kind, from what I've seen.

I'm not a racist or anything like that, but I am curious to know why this is the new trend. I have my own theories, but redditors, whats going on?
