The US has almost as many Jews as Israel. Some significant concentrations are in Manhattan, Miami, and various other urban areas.

Buddhism has also had an interesting history in China and should not be as strong a presence as the map indicates. http://buddhism.about.com/od/through...inahistory.htm
