People of every race live in every area of Los Angeles, that's the beauty of L.A. You take your pick of what you like in an area,i.e. hip and beachy, deserty areas, hip cosmo, Hollywood edgy, elegant and exclusive, Hollywood Hills, the subburbs, etc... and you can buy there. It just depends on YOU and what you enjoy.
I would strongly advise a trip down and a good tour of Los Angeles to make a decision! It's a great city and you will love it. There are many many New York transplants in Los Angeles.
