Edgemont is in theory part of the town of Greenburgh but is really part of the Scarsdale ecosystem. Edgemont was a clone of core Scarsdale when I moved here in 2007 but there has been a massive surge of Chinese since then and the school numbers shows. In Scarsdale and Northern Eastchester the Asians tend to be more Japanese expatriates. During elementary school my son's classes were 1/4 Japanese and if you add in the Chinese (including my son) the Orientals often come close to forming a majority in some of the classes. My son actually goes to Edgemont HS on the weekend for Chinese school. Not a surprise that the weekend Chinese school in his region is in Edgemont HS given the surge of the Chinese in that region.
Out of curiosity - where do Indians/South Asians live in Westchester?
