This article from Business Insider (via The Real Deal) is fascinating: it shows the most common languages in New York City beyond English and Spanish, in each Community District, which contain 200,000 to 300,000 people. Brooklyn has significant numbers of Chinese, French Creole, Yiddish, and Russian speakers.
Another map shows that Chinese, French Creole, and Yiddish actually outpace Spanish (the most common language other than English) in five Brooklyn Community Districts.
