US Cities Ranked by Black Population - Least Black to Most Black

Just had a cat lady across the street in Santa Cruz buy the house of one of the gay guys. Met her at Christmas gig for the park. She teaches English as a foreign language and came to Santa Cruz after living in Portland OR. Guess she decided to leave the fire and jump into the pan (Santa Cruz). Maybe she's some kind of lezzie, looks like a Sierra Club curdled feminist skinny anorexic vegan type. She's a walking cat lady feminist caricature. Doesn't seem nice at all, all those traffic jammed eggs, like a mean old nun. I'm glad she isn't next door to us.

The subtle data point spread for facial recognition it seems occurs at some stage of childhood and becomes more fixed and inflexible during aging i.e. you recognize many subtle distinguishing variations in the races you were raised around, but not so much the races you weren't raised around.

It's why people think that unfamiliar racial groups 'all look alike' whereas they probably don't look alike at all to each other.
