Unnamed critics state things "can" do things, while the following sentence shows there is no evidence. Then there is a follow up statement that the racial demographics show that HOAs tend to be richer (A major point of HOAs is to improve and maintain neighborhood values), and less diverse. The second part on its face might seem upsetting but, you'll find largely suburban communities ARE overall less diverse. It would maybe be relevant if they found and stated "HOAs in the same zip codes as non-HOA neighbrhoods of equal value are less diverse", that might show some racial differences, but then not even necessarily bias.

In short, bloomberg is a rag and should be used to pickup your favorite pets droppings with.
