This theory was recently explained to me. I was hoping some more learned DYers could explain it to me.

Basically it goes that Jewish groups slowly moved out of downtown NW eventually out into Oakland County. Black folks followed this Jewish "wedge" into what were white communities. It started with Dexter Davison, then Oak Park, then Southfield, now West Bloomfield.

Why were Jews and Blacks so apt to live in the same neighborhoods? Anyone seen this in action? What was the reaction of white groups when the Jews moved in, what was the reaction of Jewish groups when Blacks followed?

I've always been curious about why my black friends and my Jewish friends seemed to have such geographical and social connections to eachother.
