Physician networks in 2 California communities in 2011 with low (A) vs. high (B) concentration of blacks.

<p>(A) Hospital serving fewer black residents in HSA, % black = 0.00, clustering coefficient = 0.39, external ties = 7. (B) Hospital serving more black residents in HSA, % black = 0.13, clustering coefficient = 0.82, external ties = 3.</p
