2015年のAmerican Community Surveyのデーターを使う機会があったので、ついでにニューヨークの日本語話者（家庭で日本語を使用しているという人の数）を調べてみました。
ニューヨーク市の5区では、日本語を話す人たちの数は2015年時点で21,469人でした。NY総領事館の推定邦人数がニューヨーク州は52,688人とのことなので、ニューヨーク市以外に住んでいる人や、日本人でも家庭で日本語を話さない環境にある人などを考えるとこのくらいかなぁと感じます。
ニューヨーク市で日本語を家庭で話す人の数が最も多い地域は、ManhattanのMurry Hill, Grammy & Stuyvesant Townで、2,074人が住んでいるそうです。数が多い順に10地域をリストにしてみました。
