When I saw on Census Data, most of the Asians over in Shrewsbury/Westborough are Indian/South Asian. I am curious since my cousin, his wife, and his son are Vietnamese, where should they live? It is very hard to find a town with good public schools with many Vietnamese in Massachusetts as Cambridge, Brookline, Belmont, Newton, Lexington, Natick, Weston, Wellesley all have relatively few Vietnamese, but these towns have a high Chinese population by the way. I came across this map and this map might be helpful.
